Sorting in C Language (Bubble Sort)

noreply@blogger.com (Satyam Srivastava) — Wed, 5 Oct 2022 13:24:00 +0530

Sorting in C Language

Sorting is a process in which we rearrange the elements in any particular order, which can be set ready for further processing by the program logic. In C programming language, there are multiple sorting algorithms available, which can be incorporated inside the code. The various types of sorting methods possible in the C language are Bubble sort, Selection sort, Insertion sort, Quick sort, Merge sort and Heap sort.

Bubble Sort

It is the simplest sorting method in which program algorithm swap the adjacent elements if they are in the wrong order. This method is not suitable for large data sets as its average and worst-case time complexity is quite high. There are n-1 passes and cycle required. For Example we can see the diagram – (sorting in ascending order)

Source Code :

#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int arr[100], n, i, j, t;
//Taking input of arr size
printf("Enter number of elements :");
scanf("%d",&n);
//taking input of array elements
printf("Enter %d elements of array\n",n);
for(i=0;i<n;i++)
{
scanf("%d",&arr[i]);
}
//sorting (bubble)
for(i=0;i<n;i++)
{
for(j=0;j<n-i-1;j++)
{
if(arr[j]>arr[j+1]) /* For decreasing order use '<' instead of '>' */
{
//swaping
t=arr[j];
arr[j]=arr[j+1];
arr[j+1]=t;
}}}
//printing sorted element
for(i=0;i<n;i++)
{
printf("%d\n",arr[i]);
}
getch();
}

Binary to Decimal Conversion in C Language

noreply@blogger.com (Satyam Srivastava) — Sun, 25 Sep 2022 09:38:00 +0530

Binary to Decimal Conversion in C Language

In this section we discuss about Binary to Decimal conversion. A Binary number should we converted as following method :

Suppose we take a binary (1101)₂

then we need to find place value of each digits and add them, the addition of place value is equal to the decimal equivalent of binary.

finding place value :

1	1	0	1
1 X 2³=8	1 X 2²=4	0 X 2¹=0	1 X 2⁰=1

addition = 8 + 4 + 0 + 1 = 13

So (13)₁₀ is the decimal equivalent of binary (1101)₂

Method to convert binary to decimal

Ø Take a binary number as the input in variable bin.

Ø Divide the number by 10 and store the remainder into variable "r".

Ø dec = dec + r ´ b;
Initially, the "dec" is 0, and the "b" is 1, where the "r" variable stores the remainder of the number.

Ø Divide the quotient of the original number by 10.

Ø Multiply the "b" by 2.

Ø Print the decimal of the binary number.

Note : variable dec for decimal number, b for base, r for reminder and "bin" for binary.

Source Code :

#include <stdio.h>

#include <conio.h>

void main()

{

clrscr();

int n, bin, dec=0, b=1, r;

printf ("Enter a binary number \n");

scanf ("%d", &n);

bin = n;

while ( n > 0)

{

r = n % 10;

dec = dec + r * b;

n = n / 10;

b = b * 2;

}

printf("The Decimal equivalent of %d = %d", bin, dec);

getch( );

}

C Program To Convert Decimal Number To Binary Number without using array

noreply@blogger.com (Satyam Srivastava) — Sat, 24 Sep 2022 20:27:00 +0530

Method to calculate Decimal to Binary Number

Take a decimal input from the user

for example :

if user enter a decimal 12

We keep on dividing the number 12 by 2.

12 / 2 = 6, reminder 0

06 / 2 = 3, reminder 0

03 / 2 = 1, reminder 1.

01/ 2 = 1, reminder 1.

Decimal to binary

So Binary equivalent of 12 is 1100.

Write all reminders bottom to top. It’s binary equivalent of decimal (12)₁₀=(1100)₀₂

Source Code :

#include<stdio.h>

#include<conio.h>

void main()

{

clrscr();

int t, n, r=0, p=1, bin=0;

printf("Enter a number\n");

scanf("%d",&n);

t=n;

while(n>0)

{

r=n%2;

n=n/2;

bin=bin+(r*p);

p=p*10;

}

printf("Binary of decimal %d = %d",t,bin);

getch();

C Program for whether inputed number is an armstrong number or not by using while loop

noreply@blogger.com (Satyam Srivastava) — Thu, 22 Sep 2022 21:27:00 +0530

Armstrong Number

It is a magical number that is equal to the sum of cubes of its digits. For example 0, 1, 153, 370, 371 and 407 are the Armstrong numbers.

153 = (1x1x1)+(5x5x5)+(3x3x3)

where:

(1x1x1)=1

(5x5x5)=125

(3x3x3)=27

So:

1+125+27=153

C Program

//C Program to input a number and

//check whether armstrong number or not

#include<stdio.h>

#include<conio.h>

void main()

{

while(n>0)

{

r = n % 10;

sum = sum + (r*r*r);

n = n / 10;

}

if(sum == temp)

noreply@blogger.com (Satyam Srivastava) — Sun, 18 Sep 2022 19:07:00 +0530

Factorial in C

The Factorial is the product of all positive descending integers of n. Factorial of n is denoted by n!.

For example:

4! = 4 X 3 x 2 X 1 = 24

5! = 5 X 4 X 3 x 2 X 1 = 120

Example Program for factorial by using "for loop"

#include<conio.h>

#include<stdio.h>

void main()

{

clrscr();

int n, i;

long int f=1;

printf("Enter a number\n");

scanf("%d",&n);

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

{

f=f*i;

}

printf("Factorial of %d = %ld",n,f);

getch();

}

Example Program for factorial by using "Function"

#include<conio.h>

#include<stdio.h>

Looping statement in C Language

noreply@blogger.com (Satyam Srivastava) — Sat, 10 Sep 2022 13:20:00 +0530

Looping Statement in C

Loop is used to execute the block of code several times according to the given condition in loop. It means it executes the same code multiple times.

There are 3 types of loop –

01. while loop

02. do – while loop

03. for loop

1. while Loop –

While loop is also known as a pre-tested loop. In general, a while loop allows a part of the code to be executed multiple times depending upon a given condition. The while loop is mostly used in the case where the number of iterations is not known in advance.

Syntax of while loop :

while(condition)

{

statements – 1

statements – 2

statements – n

//increment / decrement operator if required (optional)

}

Flowchart of while loop :

e.g.

//Program for printing 1 to 10 number

//by using while loop

#include<stdio.h>

#include<conio.h>

void main()

{

int i=1;

while(i<=10)

{

printf("%d ",i);

i++;

}

getch();

}

2. do – while loop

It also executes the code until condition is false. In this at least once, code is executed whether condition is true or false but while loop is executed only when the condition is true.

Syntax :

{

statements – 1

statements – 2

statements – n

}

while(condition);

Flowchart of do-while loop :

e.g.

//Program for printing 1 to 10 number

//by using do-while loop

#include<stdio.h>

#include<conio.h>

void main()

{

int i=1;

{

printf("%d ",i);

i++;

}

while(i<=10);

getch();

}

3. for Loop

It also executes the code until condition is false. In this three parameters are given to it these are Initialization, Condition & Increment/Decrement operators

Syntax

for(initialization; condition; increment/decrement)

{

statements – 1

statements – 2

statements – n

}

Flowchart of for loop :

e.g.

//Program for printing 1 to 10 number

//by using for loop

#include<stdio.h>

#include<conio.h>

void main()

{

int i;

for(i=1; i<=10; i++)

{

printf("%d ",i);

}

Switch-Case Statement in C

noreply@blogger.com (Satyam Srivastava) — Sat, 10 Sep 2022 09:03:00 +0530

Switch-Case Statement in C

Switch-Case statement in C allows us to execute multiple operations for the different possible values of a single variable called switch variable. Here, We can define various statements in the multiple cases for the different values of a single variable. A switch statement allows a variable to be tested for equality against a list of values. Each value is called a case, and the variable being switched on is checked for each switch case.

Syntax :

switch (expression)

{

case value1:

{

Statements of case 1

break;

}

case value2:

{

Statements of case 2

break;

}

case value3:

{

Statements of case 3

break;

}

.....

default:

{

code to be executed if all cases are not matched;

}

} //End of switch case statement

Rules for switch statement in C language

Ø The case value must be an integer or character constant.

Ø The case value can be used only inside the switch statement.

Ø The switch expression must be of an integer or character type.

Flowchart of switch statement in C

Example Program :

//Example program of swith case statement

//satyamsrig.blogspot.in

#include<stdio.h>

#include<conio.h>

void main()

{

clrscr();

int ch;

printf("Enter the number of month\n");

scanf("%d",&ch);

switch(ch)

{

case 1:

{

printf("January");

break;

}

case 2:

{

printf("February");

break;

}

case 3:

{

printf("March");

break;

}

case 4:

{

printf("April");

break;

}

case 5:

{

printf("May");

break;

}

case 6:

{

printf("June");

break;

}

case 7:

{

printf("July");

break;

}

case 8:

{

printf("August");

break;

}

case 9:

{

printf("September");

break;

}

case 10:

{

printf("October");

break;

}

case 11:

{

printf("November");

break;

}

case 12:

{

printf("December");

break;

}

default :

{

printf("You have entered wrong keyword");

}

"goto" statement in C Language

noreply@blogger.com (Satyam Srivastava) — Sun, 4 Sep 2022 13:22:00 +0530

goto statement in C

The goto statement is a jump statement which is sometimes also referred to as unconditional jump statement. The goto statement can be used to jump from anywhere to anywhere within a function.

C Language में goto स्टेटमेंट एक जम्प स्टेटमेंट है कभी-कभी इसे अनकंडीशनल स्टेटमेंट भी कहते है। C प्रोग्राम में कही से कही भी जम्प करने के लिए goto स्टेटमेंट का प्रयोग करते है।

Syntax 1 –

label:

goto label;

Syntax 2 -

goto label;

label:

// C program to print numbers

// from 1 to 10 using goto statement

#include <stdio.h>

#include <conio.h>

void main ( )

{

int n = 1;

label:

printf("%d\n",n);

n++;

if (n <= 10)

goto label;

}

//Program to demonstrate

//goto statement in C Program

#include <stdio.h>

#include <conio.h>

void main ( )

{

int num;

clrscr ( );

printf("Enter any number");

scanf("%d",&num);

if (num % 2 == 0)

// jump to even

goto even;

else

// jump to odd

goto odd;

even:

printf("%d is even", num);

// return if even

getch();

return;

odd:

printf("%d is odd", num);

getch();

}

Disadvantages of using goto statement:

It makes the program logic very complex.

Use of goto makes the task of analyzing and verifying the correctness of programs very difficult.

Simply avoided using break and cnontinue statements.

if-else-if in C

In else – if a programmer can make decision among multiple conditions. In C "if statements" are executed from the top down approach. As soon as one of the if is true, the statement associated with if is executed, and the rest of the C else – if is bypassed. If none of the conditions are true, then the final else statement will be executed.

Syntax:

if (condition)

    statement;

else if (condition)

    statement;

C Program to understand the concept of "if-else" statement in C by Satyam Srivastava

If-else Statement

The if-else statement is used to perform two operations for a single condition. The if-else statement is an extension to the if statement using which, we can perform two different operations, i.e., one is for the true condition, and the other is for the false. Here, we must notice that if and else block cannot be executed in same time. The syntax of the if-else statement is given below.

if(condition)

{

//code to be executed if condition is true

}

else

{

//code to be executed if condition is false

noreply@blogger.com (Satyam Srivastava) — Tue, 9 Aug 2022 12:46:00 +0530

C - if statement

An if statement consists of a Boolean expression followed by one or more statements.

Syntax :

The syntax of an if statement in C programming language is −

if (condition)

{

statement(s) will execute only if the boolean expression is true

}

If the Boolean expression evaluates to true, then the block of code inside the 'if' statement will be executed. If the Boolean expression evaluates to false, then the first set of code after the end of the 'if' statement (after the closing curly brace) will be executed.

INSTALL WINDOWS XP FASTER

noreply@blogger.com (Satyam Srivastava) — Tue, 1 Sep 2015 15:43:00 +0530

In this post I will tell you about installation of win XP in minimum time period. Normally when someone tries to install windows XP on computer, it takes around 30-40 min to complete entire setup. It is too much time to install windows setup. I will tell you a method to install windows more faster. It will take approximately 15 minutes to complete windows installation. So to install win XP in short time please follow these steps.

Power on your computer and start with bootable windows XP cd

In first step window will load installation files.

Select any drive ( C: ) for installation.

Select NTFS to format the partition.

Setup will copy files on this drive and it will try to restart PC.

After restarting when you see Xp logo, press (Shift+F10).

It will open (CMD) prompt. In CMD prompt type (Taskmgr)

It will open task manager. Now go to “process” tab and find “Setup exe” Right click on setup.exe and select “Set priority”

You will see a submenu. Here priority will be normal. Select priority to (High) or above (Normal). Done.

This will complete installation process much faster than the normal original time.

Try it….......

DO NOT Computer Tip List

noreply@blogger.com (Satyam Srivastava) — Tue, 1 Sep 2015 15:32:00 +0530

Poor advice spreads as easily as good advice, and sometimes untrained instincts can lead you down the wrong circuit when it comes to a computer. So here is a DO NOT computer tip list: things you should avoid doing that could harm your machine.

Ø DO NOT defragment- your hard drive too often. Do it only if you are deleting a lot of files that are large, like photos. Defragging too much creates unnecessary stress on the hard drive and can do more harm than good; it reduces the life of the hard drive. If you aren’t deleting lots of files, defragging once every one or two months is sufficient. (Defragmenting: When you delete a lot of files, it leaves data gaps in the hard drive. This process removes those gaps so that your data can be accessed more easily and quickly.)

Ø DO NOT install Windows hardware updates. You DO NOT need the latest and greatest updates, contrary to what you may have heard from others. Windows security updates are good; but hardware updates often cause more problems than they solve. Install them at your own risk, as many cases of improperly installed updates have caused computer corruption.

Ø DO NOT click randomly and quickly in continued succession if your computer is not responding—like opening up a program or page online. Most times, the computer is doing something in the background (something of which you are unaware or don’t see visually). Let the computer do its thing. Clicking rapidly will not help it load any faster, and might, in fact, confuse the computer, causing it to freeze up or crash. Practice patience, and failing that, use CTRL + ALT + DEL for a force quit option.

Ø DO NOT open attachments from someone you don’t know or that seem suspicious. Viruses can be spread by e-mail, but only if one opens the included attachment or the web link. You won’t get the virus if you open the e-mail alone, but you very well could if you open the attachment or click a link in the e-mail. If the subject line of the e-mail is the supposed sender’s name, but all that appears in the body is a web link or attachment, mark it as spam and delete.

Ø DO NOT leave your computer connected to the Internet if you believe you’ve contracted a virus. This also applies for programs on your computer that use the Internet, like e-mail, music players, or chat programs. They may not work anyway, but the longer your computer maintains an online connection, the more a virus can infiltrate the machine. Unplug your Ethernet cord, turn off the Wi-Fi, and/or shut off the computer completely.

And the final, ABSOLUTELY-DO-NOT-super-bonus:

Ø DO NOT install more than one antivirus program. Most people wonder how in the world they contracted a computer virus; doubly so if they run TWO antivirus programs, but that’s probably where the problem lies. If you have Norton, you don’t need McAfee, or vice versa. Two can cancel each other out. Pick the one you like best and stick with it!

Abiding by these DO NOT tips could help you avoid making common mistakes that put your computer at risk. We want our customers to have a more satisfying, and certainly less frustrating, time working with their computers.

Create Wifi Hotspot on Windows 7 / Windows 8 Laptop Without Using any Software

noreply@blogger.com (Satyam Srivastava) — Thu, 14 May 2015 10:51:00 +0530

1. Open the Command prompt as Administrator (Right click and select Run as administrator).You can also open it by pressing Window Key + X and choosing Command Prompt (Admin).

2. Type the following command in the command prompt and press Enter.

"netsh wlan set hostednetwork mode=allow ssid=satyamsrig key=password"

Here ssid is the name of your hotspot and key is password of your hotspot.Choose both of these according to you.
3. Next,type the following command and hit enter.

"netsh wlan start hostednetwork"

You will get a message like The hosted network started.

4. Now go to Network and Sharing center and You can see your newly created wifi hotspot connection. But, as you can see, it has no network access. We need to fix this by enabling sharing of internet connection for your working Internet connection .In my case, it is wifi connection, but it can be Ethernet or any other working internet connection.

5. To enable sharing, Click on your default Internet connection and select Properties. Under the Sharing tab, tick the box saying – Allow other network users to connect through this computer’s Internet connection. Under the Home networking Connection, select the connection which is showing as your hotspot connection.

6. Your Wifi hotspot is created and Internet sharing is enabled. You can check in the Network and Sharing center that your wifi hotspot now has Internet Access.

7. Now Connect any wifi enabled device to this hotspot using the password you choose while typing the command.

8. In order to stop the Wifi hotspot, Just type the following command in the command prompt(as Administrator).

"netsh wlan stop hostednetwork"

It might come to your mind that remembering these commands is not easy. Also typing them again is tedious task. This also has a solution.

1. Write both the commands in notepad.

2. Select Save As and save the file as Batch type. Name the file anything you want but make its extension .bat .Also select All Files in Save as Type. Save it on the desktop.

3. Your batch file is created. Now whenever you need to start hotspot, just run this file with admin privileges.

4. Similar way, you can create a batch file to stop the hotspot.

This tutorial might feels you long because I explained in quite detail. However, It will not take more than two minutes to create wifi hotspot using this method.

Download batch file -- Click below links --

Start Hostspot

Stop Hotspot
