I'm learning to program, but I'm having trouble trying to get data into my app. I've been watching the Lynda Videos and they are very helpful. However, there are many times when its stated in an early video "we will cover that later" or "you don't need to know that for now" but its never covered... very frustrating. its like learning how to drive a car but then never being shown how to actually get it started. lol What I'm looking for is some type of user input code. I want to write a simple app that takes in some data, say 3 or for numbers does some math on them and spits back out some result.
