I might be able to help a little, I would like to work with reverse-engineering and I'm a really fast learner, Also, I know PHP really well and I am trying to learn C++.

#include <iostream>
using namespace std;

main()
{
const PI = 3.14159;
float circumference, radius;
cout << "What is the radius of the circle?" << endl;
cin >> radius;
circumference = 2 * PI * radius;
cout << "The circle's circumference is ";
cout << circumference << '\n';
return 0;
}
