Rating A: Maximum penalty
Rating B: no penalty
Rating C: 0
Rating D: 0
Assigned grade: B
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(){
long long int n,cn,rev=0,d;
cin>>n;



if(n/10!=0){
cn=n;
rev=0;
while(cn>0){
d=cn%10;
rev=rev*10+d;
cn=cn/10;
//cout<<rev<<endl;
}
cout<<rev;}
else if(n/10==0){
cout<<n;}
return 0;}

Grading criterion: Is each digit of the original number correctly extracted
Rating A: Each digit is correctly extracted using modulo 10
Rating B: The digits are neither extracted correctly nor stored in the reverse fashion
Rating C: 0
Rating D: 0
Assigned grade: A
