Learn recursion for beginners.

Recursion is a function that call itself. It is an important concept. Recursion should must have a base condition that stop it from further calling.

General syntax of recursion.

void fun(int x)

{

// logic

}

int main()

{

fun(x);

return 0;

}

When we call the recursion then printing is done at two time;

Printing at calling time.
Printing at returning time.

Printing at calling time:

#include<stdio.h>

void fun(int x)

{

if(x>0)

{

printf("%d",x);

fun(x-1);

}

int main()

{

int x = 3;

fun(x);

return 0;

}

Printing at returning time:

#include<stdio.h>

void fun(int x)

{

if(x>0)

{

fun(x-1);

printf("%d",x);

}

int main()

{

int x = 3;

fun(x);

return 0;

}

Difference between loop and recursion:

1. Loop is repetitive statement.

2. Recursion is also repetitive statement.But loop will have ascending phase and recursion will have both ascending and descending phase.

Types of recursion:

Tail recursion
Head recursion
Tree recursion
Indirect recursion
Nested recursion

1.Tail recursion:

This is type of recursion where everything performed at calling time.Function will not do anything at returning time.

Program:

#include<stdio.h>

void fun(int x)

{

if(x>0)

{

printf("%d",x);

fun(x-1);

}

int main()

{

int x = 3;

fun(x);

return 0;

}

2.Head recursion:

This type of recursion will perform everything at returning time.This will not do anything at calling time.

If the function is performing something at returning time it can't be easily converted into loop but it can be converted.

Program that explain head recursion:

#include<stdio.h>

void fun(int x)

{

if(x>0)

{

fun(x-1);

printf("%d",x);

}

int main()

{

int x = 3;

fun(x);

return 0;

}

3. Tree recursion.

In this type of recursion a function is called multiple time.

Program that explain tree recursion:

#include<stdio.h>

void fun(int x)

{

if(x>0)

{

printf("%d",x);

fun(x-1);

}

int main()

{

int x = 3;

fun(x);

return 0;

}

4. Indirect recursion.

In indirect recursion there may be more than one function calling each other in circular fashion.So that the first function calls second one and then second function calls third one and then third function again callback first function.

Then it become a cycle so it become recursion.

5. Nested recursion.

This is basically recursion inside recursion.

#include<stdio.h>

int fun(int n)

{

if(n>100)

{

return n-10;

}

else

{

return fun(fun(n+10));

}

int main()

{

int x = 3;

int d = fun(x);

printf("%d",d);

return 0;

}

Web development for beginners.

2020-12-08T15:04:00.003+05:30

Web development for beginners.

This course will make you an expert in web development.But before moving on this advance topic you should be very well versed with your fundamentals of programming.Because it will boost your journey to become full stack web developer.

This course is designed for absolute beginner covering all aspect of web development.Here you will find all topic covering all aspect of web development.

Before knowing what is a full stack web developer or what work a full stack developer does,we should know what is frontend and backend

What is frontend?

Let's understand it with very simple example we all are aware from facebook,when we type facebook.com in our web browser it redirects us to official website of facebook.Where it wither tells us to login or signup.This is frontend part of facebook.So basically frontend part communicate with clients. The part which communicate with client is called as frontend part.

What is backend?

Let's continue with our facebook example while we enter our details like name,email,password.We must imagine where all these data goes.All these data gets stored inside a database.So that again when we logged in, facebook can authenticate a valid user and must identifies every user as independent identity.

So this part come into playing with data.This is what a backend developer does.

So know i hope you all must be aware from frontend and backend part in brief. Now come to our main topic we should now in position to know what is a full stack we developer.So a developer which can handle both frontend and backend part is called as a full stack web developer.This is what we will cover in this course.

Tools that we required to become a frontend web developer

There are very basic tools or you can say a frontend web developer should must know these tools.

These are :

HTML
CSS
JAVASCRIPT

1.HTML

This is what a web developer should must know.Without HTML

you can't consider any web page or web application.This should be known by every web developer.HTML is used to structure our web page.The page that you are seeing right now is structure using HTML.

2.CSS

This is used to give style to web page.Without CSS our web page might not looks so good and interactive as compared to when we use CSS to designed our web page.

So you can consider CSS as web styler who style our web page.

3.JAVASCRIPT

This is used to add interactivity with our web page.Have you ever seen when we click on button then modals open up or when we click on drop-down menu then it will display all element.All these things are implemented using javascript.

As i think according to today market skills every one should must know javascript.Because javascript is used every where in web application from frontend to backend.

Tools that we required to become a frontend web developer

To become backend web developer there are many popular language you can pick up any one and just learn it thoroughly.

In this course we will learn two most popular backend language:

PHP
Node.js

Question: Write a program to find whether an element is present in an array or not?

Explanation:

A[10] = {10,20,30,40,50,60},ele = 60

We have to find whether element 60 is present in our array or not.

Programs:

#include<iostream>

using namespace std;

int main()

{

int A[10] = {10,20,30,40,50,60},pos,ele,flag=0;

cout<<"Enter an element to search:"<<endl;

cin>>ele;

for(int i=0;i<6;i++)

{

if(A[i] == ele)

{

flag = 1;

break;

}

if(flag==1)

{

cout<<"Element found";

}else{

cout<<"Element not found";

}

return 0;

Before insertion: A[] = {10,20,30,40,50,60};

Insert an element = 100 at position index = 3.

After insertion: A[] = {10,20,30,100,40,50,60};

Program:

#include<iostream>

using namespace std;

int main()

{

int A[10] = {10,20,30,40,50,60},position = 3,element = 100;

for(int i=5;i>= position;i--)

{

Array.

Array is basically a contiguous memory allocation of same data type.It can't be of different data type.

It is a homogeneous continuous memory allocation.

We will learn about:

What is an Array
Declaring and initializing
Accessing array element

1.What is an array:

Array is basically a contiguous memory allocation of same data type.It can't be of different data type.

It is a homogeneous continuous memory allocation.

2.Declaring and initializing:

int A[5];

The above statement is used for declaring an array.

int A[5] = {1,2,3,4,5};

The above statement is used for initialing an array.

Program to illustrate difference between declaring and initializing:

#include<iostream>

using namespace std;

int main()

{

int A[5];

int B[5] = {1,2,3,4,5};

for(int i=0;i<5;i++)

{

cout<<"Enter element for array A";

cin>>A[i];

}

for(int i=0;i<5;i++)

{

cout<<A[i]<<" ";

}

cout<<endl;

for(int i=0;i<5;i++)

{

cout<<B[i]<<" ";

}

return 0;

}

3.Accessing array element:

We can access array element with their position index.

Program that will explain how to access array element:

#include<iostream>
using namespace std;
int main()
{
int A[5];

for(int i=0;i<5;i++)
{
cout<<"Enter element for array A";
cin>>A[i];
}

for(int i=0;i<5;i++)
{
cout<<A[i]<<" ";
}
return 0;
}

Data structure and algorithm for free

In this blog you will get to know each data structure and algorithm in details for free.This course is designed absolutely for free for beginners.Each topic is explain in depth for free for beginners.

But before moving to understand each topic in depth we should know fundamentals of programming.So prerequisite of this course would be familiar with fundamentals of programming like how to take input,outout,loops,functions.

If you don't know you can click here to learn fundamental of programming for free in depth.

But before moving to know what is data structure and algorithm we should definitely know what is programming.

Programs:

A program is set of instructions which perform some operations on data.Data is important part of program.When a program executes it operates on some data.

Data structure and algorithm:

How we organise data in main memory during execution of program this is known as data structure and algorithm.This become very important part for any program that you they are organizing their data so that it could be used very effectively.How our program is using our data.What is complexity of our program.These are very important factor when we designed an algorithm to solve our problem.

So we can say that data structure is all about how you are going to store your data in your main memory so that it could be effectively used by your programs.

Now in this course you will get to know each data structure and algorithm in depth for free.

Here we are going to use C as our fundamental language to implement our data structure.Because if you will use C++ then you have STL to do everything and similarly for java we have collection class.

If you want to learn C in depth then click here.

C is not having any built in data structure.That's why we are going to use this because it is not sufficient to know data structure.It become very important for us how to implement them also.

Types of data structure:

Physical data structure
Logical data structure

1.Physical data structure

These are type of data structure which helps in how to organise your data in main memory.

Example of physical data structure.

Arrays
Matrices
Linked list

2.Logical data structure

These are type of data structure which helps in how data can be utilized very effectively.

Example of logical data structure.

Stack
Queues
Trees
Graph
Hashing

We will discuss each of them in depth.Here is topic wise links of each data structure.

Function in C++ language.

Function is basically a block of statement which is used to perform some specific task.

In C++ language we have 4 type of function.When we declare a function then it tells the compiler about return type of function,parameter of function and it's function name.

In C++ language we divide large program into blocks and call them as and when they required.

We will discuss function in depth in this blog.

Types of function.

Function without parameter and without return type.
Function without parameter and with return type.
Function with parameter and without return type.
Function with parameter and with return type.

We will discuss each of them with very basic example:

1.Function without parameter and without return type:

#include<iostream.h>

using namespace std;

void sum()

{

int a,b,sum=0;

cout<<"Enter first number:";

cin>>a;

cout<<"Enter second number:";

cin>>b;

sum = a+b;

cout<<sum;

}

int main()

{

sum();

return 0;

}

2.Function without parameter and with return type:

#include<iostream.h>

using namespace std;

int sum()

{

int a,b,sum=0;

cout<<"Enter first number:";

cin>>a;

cout<<"Enter second number:";

cin>>b;

sum = a+b;

return sum;

}

int main()

{

int x = sum();

cout<<x;

return 0;

}

3.Function with parameter and without return type:

#include<iostream.h>

using namespace std;

void sum(int a,int b)

{

int sum = a+b;

cout<<sum;

}

int main()

{

int a,b;

cout<<"Enter first number:";

cin>>a;

cout<<"Enter second number:";

cin>>b;

sum(a,b);

return 0;

}

4.Function with parameter and with return type:

#include<iostream.h>

using namespace std;

int sum(int a,int b)

{

int sum = a+b;

return sum;

}

int main()

{

int a,b,x = 0;

cout<<"Enter first number:";

cin>>a;

cout<<"Enter second number:";

cin>>b;

x = sum(a,b);

Loops in C++.

Loops in C++

In C++ loops is basically of three types.

For loop
while loop
do while loop

We will learn all of them in depth with a question so that it becomes easy to learn and understand.

Question: Write a program in c language which will take input from user and print all number in between 1 to entered number?

1.For loop

#include<stdio.h>

int main()

{

int n,i=1;

cout<<"Enter a number";

cin>>n;

for(i=1;i<=n;i++)

{

cin>>i;

}

return 0;

}

Syntax of for loop is:

for(initialization;condition;increment/decrement)

{

//logic

}

Explanation:

According to question user will enter a number and we need to print all number between 1 to that number.So we take input from user and inside for loop we initialize our for loop to start from 1 and go till entered number.For each iteration we increment i so that when matched conditions found it terminates for loop and comes out of loop.

And for each iteration we have printed the number.

2.While loop

#include<stdio.h>

int main()

{

int n,i=1;

cout<<"Enter a number";

cin>>n;

while(i<=n)

{

cout<<i;

i++;

}

return 0;

}

While loop is also called as entry controlled loop because it first checks the conditions.If conditions found to be true then only it enters in loop otherwise it skips the loop.

So in above example we have first initialize a variable i = 1.And before entering in while loop we checked the condition since 1<=n ( suppose n=10) then it will enter into loop and print that number.

One important point that we should keep in our mind that inside our while loop we must increment our variable otherwise it will lead to infinite loop condition.

3. do-while loop

#include<stdio.h>

int main()

{

int n,i=1;

cout<<"Enter a number";

cin>>n;

{

cout<<i;

i++;

}while(i<=n);

return 0;

}

do-while loop is called as exit-controlled loop because it first executes a statement then check conditions.If our initial condition is found to be false then also it will execute for once.That's why it is known as exit-controlled loop.

}

While loop is also called as entry controlled loop because it first checks the conditions.If conditions found to be true then only it enters in loop otherwise it skips the loop.

So in above example we have first initialize a variable i = 1.And before entering in while loop we checked the condition since 1<=n ( suppose n=10) then it will enter into loop and print that number.

One important point that we should keep in our mind that inside our while loop we must increment our variable otherwise it will lead to infinite loop condition.

3. do-while loop

#include<stdio.h>

int main()

{

int n,i=1;

printf("Enter number");

scanf("%d",&n);

{

printf("%d",i);

i++;

}while(i<=n);

return 0;

}

C++ language

C++ is powerful general purpose programming language.It is an extension of c language.It is a mid level programming language.It is used to develop operating system,browsers ,games etc.C++ is very popular programming language.It was developed by Bjarne stroustrup in 1979.

Features of c++.

The most important feature it is object oriented.
It is simple language.
Structured programming language.
Powerful and fast.
Most secure and fast than C.
Platform dependent.
Memory management.

We will discuss each topic of C++ in depth.We will discuss topic wise so that you can understand each topic in depth and with clarity.

Topics:

1.Getting started with C++.

2. Loops in c++.

3.Function in C++ language.

Getting started with C++.

In this blog we will learn about fundamentals of C++.For example how to take input,how to print output etc.This is what every student who wants to learn c++ should definitely know.

So let's understand all these things with very basic example:

#include<iostream>

using namespace std;

int main()

{

int a,b,sum=0;

cout<<"Enter first number";

cin>>a;

cout<<"Enter second number";

cin>>b;

sum=a+b;

cout<<"Sum is"<<sum;

return 0;

}

Above program is used to find sum of two number in c++.Now understand each line of above code in detail.

1. #include<iostream>

In programming language we call it as header file,which includes all details required to carry out current program.Like in our case we are taking two input from user so this header file includes all functionalities required to take input from user.

2.using namespace std

Here this line is used so that we can use all standard things in c++.

For example if we don't use this line then for writing cin we have to write syntax as

std::cin>>

otherwise we write syntax as cin>>

3.int main()

This is a function don't worry we will learn it in depth here just remember it that it is simply a function.

4.cout<<"Enter first number";

This statement is used to print information on screen.Like in our case it is will print Enter first number.

5.cin>>a;

This statement is used to take input from user.In our case it will take input from user as an integer.

6.sum = a+b;

I don't think this statement needs any explanation.This is a simple arithmetic operation.It will store sum of a and b into sum variable.

7. Finally it will print sum of two number as a result.

Getting started with C language.

In this blog we will learn basic of c language like how to take input,how to print output etc.These are very basic things that every student should know before moving on.

I will explain all these thing with very basic example,which is easy to understand.

#include<stdio.h>

int main()

{

int a,b,sum=0;

printf("Enter first number");

scanf("%d",&a);

printf("Enter second number");

scanf("%d",&b);

sum=a+b;

printf("Sum of two number is %d",sum);

return 0;

}

Explanation:

This is a simple program which takes two number from user and print their sum as a result.

#include<stdio.h>

In programming language we call it as a header file.This header files includes all information required to carry out our particular program.

Like in our case it is included because we need to take input from user and print output.

2. int main()

This is a function don't worry we will learn it in depth here just remember it that it is simply a function.

3. printf();

This statement is used to print information on screen.Like in our case it is will print Enter first number.

4. scanf();

This statement is used to take input from user.In our case it will take input from user as an integer.

5. sum = a+b;

I don't think this statement needs any explanation.This is a simple arithmetic operation.It will store sum of a and b into sum variable.

6. Finally it will print sum of two number as a result.

C language

C is powerful general purpose programming language.It was developed by Dennis Ritchie in 1972.It used for many purpose like developing system software,operating system,compilers etc.It was initially used for developing system works.C language is procedural programming language using top-down approach.

In this blog you will get to learn all topics of c language in depth.Here we have divided it into topics so that it will be ease for user to learn faster.

Features of c language:

It is general purpose programming language.
Modularity.
Fast and efficient.
Mother of C++ programming language.
It is mid level programming language.
Rich in libraries and functions.
It is simple,machine independent.
Portable.

Programming.

To communicate with computer we must know a programming languae.It's just like how we human being communicate with each other likewise to communicate with computer we must know a programming language.

So basically we should know what is a programming language?

Program is basically instructions given to computer to perform a specific task.For example let's understand this with an example,suppose we want to find factorial of a given number.So we must give instructions to computer to fins factorial of a given number.

There are many programming language but in this blog we will discuss C/C++ perform our specific task.

C is basically a superset of C++.
