Write C++ Program to find the Reverse of a given number

Code:

#include <iostream>
#include <math.h>

using namespace std;

//Returns the reverse of the entered number
int findReverse(int n)
{
int reverse = 0; //to store the reverse of the given number
int remainder = 0;

//logic to compute the reverse of a number
while (n != 0)
{
remainder = n % 10; //store the digit at the units place
reverse = reverse * 10 + remainder;
n /= 10;
}

return reverse;
}

int main()
{

//variable declaration
int n;
int reverse = 0;

//taking input from the command line (user)
cout << " Enter a positive integer to find the reverse of : ";
cin >> n;

//Calling a method that returns the reverse of an entered number
reverse = findReverse(n);

cout << "\n\nThe entered number is " << n << " and it's reverse is :" << reverse;

cout << "\n\n\n";

return 0;
}
