Kruskal’s algorithm : Reference

Pritesh — Fri, 12 Apr 2013 03:36:13 +0000

Image Description AD and CE are the shortest arcs, with length 5, and AD has been arbitrarily chosen, so it is highlighted. CE is now the shortest arc that does not form a cycle, with length 5, so it is highlighted as the second arc. The next arc, DF with length 6, is highlighted using(...)

Bitwise Left Shift (

Pritesh — Sun, 24 Feb 2013 18:35:00 +0000

Bitwise Left Shift Operator in C It is denoted by << Bit Pattern of the data can be shifted by specified number of Positions to Left When Data is Shifted Left , trailing zero’s are filled with zero. Left shift Operator is Binary Operator [Bi - two] Binary means , Operator that require two arguments(...)

What is meaning of (++*ptr) in Pointer ?

Pritesh — Sat, 02 Feb 2013 21:54:03 +0000

In the previous topic we have studied Precedence of Value at and Address Operator of Pointer. In this chapter we will be looking more advance form of pointer. We are looking one step forward to learn how (++*ptr) works ? Meaning of (++*ptr) in C Programming : Consider the Following Example : int num = 20(...)

What is the size of Pointer variable in C ?

Pritesh — Sun, 20 Jan 2013 23:30:00 +0000

In the previous chapter, we have learnt about the memory organization of the pointer variable. In this chapter we are learning to compute or find the size of pointer variable. What is the size of Pointer variable in C ? How to calculate size of Pointer ? Consider the following memory map before declaring the(...)

Data Type is Storage Format that can contain a Specific Type. When computer programs store data in variables, each variable must be assigned a data type.

1-D Array – Compile Time Initializing in C Programming

Pritesh — Sat, 05 Jan 2013 18:40:00 +0000

Whenever we declare an array we can initialize array directly at compile time. Initialization of an array is called as compiler time initialization if and only if we assign certain set of values to array element before executing program. i.e at Compilation Time.

Basic Stack Operation : Data Structure

Pritesh — Sat, 05 Jan 2013 06:56:00 +0000

Primitive Basic Stack Operation in C We know that Stack can be represented using an array. Stack is open at one end and operations can be performed on single end. We can have different primitive operations on Stack Data Structure. Creating Stack Data Structure : typedef struct stack { int data[MAX]; int top; }stack; Basic(...)
