C Program to calculate the reverse of any number:
This is program shows how to find the reverse of any number which is input from user.
In which we find the reverse of number.
For Example: User input the number which is 1592. then the reverse of number is 2951.

ALGORITHM:-

step 1 : Start
step 2 : Input any number from user
step 3 : Find the % mod by 10 and add in another number which
         multiplied by 10 and stored in third variable
step 4 : Divide the number by 10
step 5 : Stop

PROGRAM CODE:-

#include<stdio.h>
#include<conio.h>

void main()
{
    int num,r,rev=0;

    printf("Enter any number : ");
    scanf("%d",&num);
 
    while(num)
    {
         r=num%10;
         rev=rev*10+r;
         num=num/10;
    }

    printf("Reversed of number: %d",rev);
    getch();
}

OUTPUT:-

Enter any number: 1589

Reversed of number : 9851
