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>
#include<cmath>
using namespace std;
int main()
{
 unsigned int n,rev;
 rev = 0;
 cin>>n;
 //First we try to find the number  of digits of  n
 int i = 0;
 int temp = n;
 while(temp!=0)
      {
       i++;
       temp= temp/10;
      }
// Now, we just take every digit of n and multiply it by a suitable power of 10 to get the reverse number
 int j = 0;
 while(n!=0)
      {
       unsigned int k = n%10;
       int l = i - j - 1;
       unsigned int m = pow(10,l);

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>
#include<cmath>
using namespace std;

int main(){
int n,a,x,m=0,y=1;
cin>>n;
while(n/y>=10) y=y*10;
a=y;
for(int i=0;i<log(a)/log(10)+1;i=i+1)
{x=(n/y)%10;
 m=m+x*pow(10,i);
 y=y/10;
}
cout<<m;
}
