C Program to reverse a given number !

#include<stdio.h>

int main() {
   int num, rem, rev = 0;

   printf("\nEnter any no to be reversed : ");
   scanf("%d", &num);

   while (num >= 1) {
      rem = num % 10;
      rev = rev * 10 + rem;
      num = num / 10;
   }

   printf("\nReversed Number : %d", rev);
   return (0);
}

#include<stdio.h>

int main() {

int num, rem, rev = 0;

printf("\nEnter any no to be reversed : ");

scanf("%d", &num);

while (num >= 1) {

rem = num % 10;

rev = rev * 10 + rem;

num = num / 10;

}

printf("\nReversed Number : %d", rev);

return (0);

}

Output :

Enter any no to be reversed : 123
Reversed Number : 321

1 2	Enter any no to be reversed : 123 Reversed Number : 321
