Coding of reverse no

i am a learner. #include <iostream.h> #include<iostream.h> using namespace std; main() { int no = 0, remainder; <pre><code>int n, reversedno = 0, remainder; cout << "Enter an integer: "; cin >> n; while(n != 0) { remainder = n%10; reversedno = reversedno*10 + remainder; n /= 10; } cout << "Reversed no is = " << reversedno; return 0; </code></pre> }
