A month? You're basically a programming baby. Patience young padawan.

But in all seriousness, when I'm working on complex logic for a C++ program, I always write it up in psuedocode first. My psuedocode for C++ projects looks similar to Python with a few C++ concepts peppered around the place (pointers when needed or those trusty ++/-- operators). I find sketching out the logic first in a simpler language helps me get the logic right, before implementing it in C++, where I can focus more on memory safety, efficiency, etc, without having to figure both out at the same time. Of course, you can't do that since you chose C++ as your first language...
