I've been learning c++ for some time now using learncpp.com, but looking back i've realised that I've rushed and that I need to go over certain things. I have a couple of questions:
a) In chapter 1.1 on learncpp.com, they say "However, C++ also comes with a library called the C++ standard library that provides additional functionality for your use. One of the most commonly used parts of the C++ standard library is the iostream library". I'm confused. So is iostream sort of like a sub-library in the C++ standard library?
b) what are object files specifically? (so, for example are they binary code, which the linker puts together to create an executable file?)
c) does "building" mean to both compile and link your code?
