starting to get serious about programming, but hitting some bumps in the road

First let me say how good it feels to be around an online community of skilled developers. I feel like I can get some real guidance here. Long story short, I'm trying c++ again because I'm waiting for epic to release UE4. Apparently they are doing away with Unrealscript and replacing it with straight c++. It was confirmed in some article I was reading and the author goes on to say something like "Start learning some c++ and prepare yourself. Trust me, its not as hard as you think". So I decided to give it another go. And this time I'm having a little more success because im not really thinking about games. Just trying to learn it. Anywho, Im stuck on function parameters. This youtuber guy Bucky (Thenewboston) explains it ok, but I feel like he's leaving out some valuable information. So I searched around a little more and found this guy All his code worked, then when I started mixing other stuff with it like other statements and functions it still worked. The only time I was getting errors was when I screwed up and didnt realize it. QUESTION... The way I understand it function parameters are just functions that require more data to run. int FuncTwo(int G); // This is the prototype int main () { int F = 5; int result; result = FuncTwo(F); cout << "The result is " << result << endl; return 0; } int FuncTwo(int G) { G = G + 5; return G; } Am i correct on this............ result = FuncTwo(F); FuncTwo(F) is doing 3 things. First its holding a value of 5, hence variable F to take with it to the function FuncTwo. While there it calculates that with whatever equation is in that function. Then return G tells it to bring it back to main. But it would already do that anyways in c++, but since the variable "result" is in front of the function call its automatically telling that function that whatever the result will be to store it in that variable when it comes back? This stuff i getting really tricky. But I gratefully appreciate any help. thanks everybody.

Not to sound noob but whats going on with int num2 = increaseBy2(num1);
I dont think I have studied that yet. What does (num1); mean?

num1 is a integer variable created earlier, set to equal 5.

lol oh ok. I get it. Sorry. Still learning.

I feel like an idiot now.

That's a good sign, it means you're learning Stick with it, even if you don't quite understand it, it'll start to sink in with time. The best thing is, after getting a tutorial or example to work, is to modify it. Try to break it, but try to break it in a way that you can predict. Add a few more functions. Call functions from other functions. Just play around, have fun for a bit, and get comfortable with it.
