hey I need some help from someone out there that is super bored. I'm trying to help a friend with his c++ hw, but I dont know anything about c++. On top of that I cant get my visual studio to work to debug this stupid thing.

1.) anyone wanna take a look at the following code and help me tweak it to at least get it to compile without errors and output something?
2.) is there a decent free program out there that works well for compiling and running c++ programs? (like using textpad for java)
