Comments are in the source code for humans to read, not for computers to execute..
What is the use of comments?
Comments are text notes added to the program to provide explanatory information about the source code. They are used in a programming language to document the program and remind programmers of what tricky things they just did with the code and also helps the later generation for understanding and maintenance of code.
Should code have comments?
A handy rule of thumb is: a comment should only be added to answer a question that the code can’t. If you aren’t confused by what a piece of code is doing, but rather why it’s doing it at that moment, then a comment should be added.
