Hello, I think I know what the difference is, but I havent been able to find a clear definition/example of each. I am posting my assignment code below which is supposed to have at least one value returning function, and one void function in it. I believe that I am using a value returning function with my functions slope() and/or slope2(). All the rest are void. Im not sure if I am right so any tips/further clarification would be greatly appreciated. My program works how it should, I am just looking for some help understanding functions from other eyes.
