C program to enter value by user.

                                 While we need to enter value by the user or keyboard in c programming than we need to use scanf function. Which get the input from the user and store it in the variable. It is general input function of c programming. scanf function is used to provide the interactive feature to program which make program  user friendly. General format of scanf function as below.

Syntax:
               scanf("%d",&<variable name>); // To enter integer value by user.
               scanf("%f",&<variable name>); // To enter float value by user.
Note: 
              Here must write & before the variable in scanf(); because if you not write  &<variable name> than it store garbage value in variable. 

Source Code

#include<stdio.h>

void main()
{
        int no;
        clrscr();

        printf("Enter number::");
        scanf("%d",&no);

        printf("Number enter by you is:: %d",no);

        getch();
}
