What happens when you type ls -l *.c in the Shell?

Why use Libraries?

A great perk of using these nifty libraries is execution speed at run-time. Because the…


WHAT IN THE WORLD IS GCC?!?

Great question, GCC stands for GNU Compiler Collection. This is an optimizing compiler that supports various programming languages. One of them being, the C Language that we are currently learning at Holberton School through project based and collaborative peer learning.

Compilation

Compilation is a very heavy duty process of converting source code into object code. I like to say the compiler saves the day by doing the nitty gritty work while we sit back and watch. It always checks the source code for errors before generating object code. …
