Questions

I write down questions here when they're annoying enough, but I'm too lazy to check them now, so I had to save them to feel relief.

Answered#

• What does std:: mean?
  The C++ standard library lives in the std namespace.
• What does << mean?
  It sends data to the output stream.
• What is abstraction?
  Using something through a simpler interface without needing to know the implementation details. Example: I call a function and use its result without even knowing what the body does.
• What is a translation unit?
  A preprocessed .cpp file, meaning the state after expanding directives such as #include and #define.

Nothing here right now. I probably have a clear mind, or I forgot to write the question down.
