Get a sheet of paper and write "Turn me over" on both sides. Then, do what the paper says.
#include <iostream>using namespace std;void turnOver(void);int main(){ cout << "You write on a piece of paper \"Turn me over\""; cout << "\nYou then write on the other side \"Turn me over\""; cout << "\nYou then do what the paper says.\n"; turnOver(); return 0;}void turnOver(void){ cout << "The paper says \"Turn me over\""; cout << "\nYou turn it over.\n"; turnOver();}
