Study skills for programmers

Promoting these video series so that I get more interest in study skills and computer programming in general, more affluence for my blog and youtube channel. but most importantly to share.

Today I am also adding a donate button with the only intention to allow the learner to contribute monetarily so that this project is kept alive. Stop supporting huge billionaire academic corporations and start embracing Open Source Software and Documentation. It's noble, fair, and serves the people at its core.

Functions in pseudo-code

Functions are code blocks that execute where the function call is placed in the code. That could be inside the main function, inside another function that is called inside main, inside another function that is called inside another function that is called inside main, and so on.

Function prototypes serve the builder to inform a priori what types(how much allocation must be made and how must it be divided) does the function return and receive(as parameters).

Function definitions serve to specify the code to be executed, when the function call is encountered in the code.
