i know this is jack poop to all you expert programmers out there, but I just wanted to share my last 45 minutes.. the real reason I feel good about this code i wrote is because i did the whole thing without referencing back to a tutorial, or an example (shows I'm learning something) its definitely the longest code I've written off the top of my head (even though it is SUPER short compared to an actual useful code).
also I'd like to thank the people on the forums, because I was struggling with the concept of using functions besides main, but now I've got it.. I would gladly take any tips on improving this code or tips in general! ahhh my first REAL written program. it DOES feel good :)
I am having trouble thinking of a way for it to loop back to main after either option is finished.. (besides exit)
Code:#include <iostream>
#include <string>
using namespace std;
int calculator ();
int bottles_of_beer ();
int exit ();

double divide (double x, double y)
