Problem: Write a C++ program that takes a positive integer n as input from the user and prints a number m whose digits are in reverse order as compared to n. If the number ends in one or more zeroes, then those zeroes should be ignored while printing the reverse.

Student submission:
#include <iostream>

using namespace std;

int main()
{

 int n,m=0;
 cin>>n;

 int d;

 while(n>0)
 {
   d=n%10;
   m=m*10 +d;
   n=n/10;
 }

 cout<<m;
 return 0;

}

Grading criterion: Is the loop iterated correctly for updating all digits of the number to the final number
Rating A: Correct while or for loop which runs till the correct reversal happens and then terminates
Rating B: Wrong loop which runs for an incorrect number of times causing a different final number
