C++ is one of the most popular programming languages in the world, and for good reason.

Ethical hacking is when a programmer has permission to use their technical skills to intentionally break into computer…

One of the best ways to learn a programming language is to take your knowledge from theoretical to practical by doing coding projects. These are projects that are easy to conceptualize, typically have one or two functions (like a random-number generator or a countdown timer), and can be completed relatively quickly.
