How is QB64 written?

[RhoSigma]

So, would it be helpful to learn C in order to better understand and/or contribute to QB64PE?

I can only advise you not to start with “C” now. Both together go wrong. Since you started with Basic, you should stick with it until the basics are learned. After that you can still try "C", but not both together as a beginner. 

See an example here:  https://qb64phoenix.com/forum/showthread...586&page=2

I had already installed Code::Blocks, so I ran your code after pasting it in and it worked well. Thanks. And, ya, I am kind of stubborn this way, so I will probably start working on C at the same time as QB64PE. I got 100 pages into a C book some time ago, so it is not too confusing to me (yet). Right now I am trying to find a more modern tutorial for C, since the book I had at the time was printed in about 1992 or so.

In light of this discussion, if I were to want to learn C, can any of you recommend an online Tutorial -- or other source -- for it? Preferably without being loaded with advertising and pop-ups. Something like Terry's tutorial would be great.

https://legacy.cplusplus.com/doc/tutorial/

or

https://en.cppreference.com/w/

Something like that would be great, but for C, not C++.

BTW - C and C++ are almost similar in its basics, the complicated stuff in C++ comes with OOP using classes, templates and stuff like that.
