Two pigs in a barn:

#include <iostream>
int main()
{
  using std::cout;
  cout << "Eggs eat stonks"

  int a = 65;
  int b = a/3;
}

Wait, what are the rules of this game again?

Nice, Moschops.
For amusement, I am rewriting infamous1987's post as a proper OOP program.
I'll let you know when I'm done.

Well, you broke the first one by using the CODE tag.

The first rule of Athlete's Salary is you DO NOT TALK ABOUT Athlete's Salary

If you place #include <iostream> there the program actually works...
