whoops!

"int y" should be "int y=0" and "y = k * ( x%10 )" should be "y += k * (x%10)"

num = 0

for (i=0; i

Sorry the for loop goes from last to 0. And we decrement "i"

A simple code example. Here the number to be reversed is 621.

#include     
  
int main() 
{
        
  int y=0, k=1, x=621;
  int a;

  while ( x > 1 ) 
  {

    a = ( x % 10 );
    y = y *10 + a;
    x /= 10;
  }

  

  printf ("%d", y);
  return 0;

}

And the output will be 126.
