Hi, for this code are all your functions written inside the class or are they written in another file? It's hard to tell. I notice you have two .h files included and I'm curious about what's in those. I'm writing a similar code but I have a .h that includes my class, and two other files, one for functions and one for main. I wanted to play with your code and break it and fix it to see how it works to help me understand classes better. Thanks for...
