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: Are digits being correctly updated and utilised to calculate the number's reverse
Rating A: The digits from last to first digit of the number are correctly added to the reversed number
Rating B: The update of the number's reverse isn't happening correctly
Rating C: 0
Rating D: 0
