What is initialization ?

Hello friends, I was forget to tell you about initialization so we will cover initialization here.

Initialization:

Variable are created for use in the program hence we need a value to the variable before using the variable.There are two type initialization-

• Compile time
• Run time

Compile time:

The initial value of the variable is known before execution of the program before the execution of the program.

Dynamic (run ) initialization:

If refers to run time initialization   initial value of the variable is not known until the program is executed.

Comments:

Comments are special feature of programming it is used to provide discussion to the programmer all user. These comments are only available therefore only available the logic as well as meaning of the variable used.

Single line comment :

It is use to give description that continuous in a single line the symbol use  // 

Multiple line comment :

Multiple line comment meant for describing statement 

The symbol used 

/*----------

  -------------*/

For Ex.:


/* program for
  comment explanation */
main( )
{
printf("Hello to all");
//program ends
}

Wap  a program to input two numbers and swap the content -
#include<stdio.h>
main()
{
int n1,n2,temp;
printf("Enter value of n1 and n2:");
scanf("%d %d ",&n1,&n2);
temp=n1;
n1=n2;
n2=temp;
printf("After swap n1 and n2 is %d %d ",n,n2);
}

Thank you;
