This is the Linux and Raspberry Pi version of the first book which uses VS Code.  All code updated plus screenshots mostly from Raspberry Pis and a new book cover!

This was compiled between 1996 and 2003 by Nick Parlante at Stanford college. It’s a 45 page PDF that summaries all the basic features of C.

It saves having to search online or through a reference book (I have the excellent O’Reilly C book as well). It has a few pitfalls to show you things to avoid and lots of short source examples.

It got very messy because I was trying to have all the moving objects (Player ship, asteroids, bullets, aliens ship) all based on a common ancestor class but then was trying to manipulate those instances of the ancestor class and downcast back from the ancestor instances and I don’t think you can in C++. Compiler errors galore!

It was the wrong approach and I wasn’t using virtual functions. So instead I’m doing it step by step, adding on new features. Much like the original C development in 13 different steps.

Here’s the slightly shorter asteroids.cpp:

// Asteroids C++ 2020 Chapter 27
#include "game.h"

int main(int argc,char * args[])
{
	Game g;
	g.InitSetup();
	g.GameLoop();
	g.FinishOff();
    return 0;
} 

There are other classes used from Game. I haven’t put everything in one “God” class!
