Write a C program to read a four digit number and display it in reverse order.

#include<stdio.h>

#include<conio.h>

void main()

  {

    int c=0,n,r,s=0;

    clrscr();

    printf("\n Enter any 4 digit number: ");

    scanf("%d",&n);

    while(n!=0)

    {

     r=n%10;

     s=s*10+r;

     n=n/10;

     c=c+1;

    }

    if(c<=4)

    printf("\n Reversed number is %d",s);

    else

    printf("\n It is not a 4 digit number");

  getch();

  }
