Grading criterion: Reading Input datatype
Rating A: Correctly Reads an integer as input
Rating B: Fails To Read Input or reads a different datatype
Rating C: 0
Rating D: 0
Assigned grade: A
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(){
unsigned int n;
cin>>n;
int z=0;
while(1){
int k=n%10;
z=z*10+k;
n/=10;
if(n==0) break;
}
cout<<z;
}
