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.

int main()
{
int n,x;
cin>>n;
while(n>0)
{
x=n%10;
n=(n-x)/10;
cout<<x;

- header (includes, using namespace, etc)
- main syntax
- variables declaration
- overall syntax"
Rating B: Problems are present in the code(eg: printing unnecessary strings, missing semicolons & braces, wrong/missing declarations, wrong header files)
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(){

int n;
cin>>n;
int m=0;
while(n){
m=10*m+n%10;
n=n/10;
}
cout<<m<<endl;
return 0;
}
