I'm a student in college taking intro to c++ online.

There are online tutorials you might want to look at and learn from. Structured for a beginner to learn the basics and more.

There's a tutorial here at CPlusPlus, though it is outdated. Mostly C++11, a little C++14. NO C++17 or later:

Another tutorial that covers c++11/14/17 and is updated regularly:
https://www.learncpp.com/

Learn C++ is the site I recommend.
