First of all, you're going to need a windows computer. Also, you're going to need a compiler. The best compiler(in my opinon), is Dev-C++.
The download link is here (sourceforge)
Go ahead and install it
Just leave all the options as-is, unless you know what you're doing
Install it onto C:\ like it says, it makes everything easier
It might give you a message asking about code completion function. Don't bother with it, you don't need it yet
If you get this, you're good to go!
