What are good comments in code?

Comments should be useful high level descriptions of what the program is doing. They should not restate something that is “obvious”. By using appropriate variable names, much of a program can be (almost) as easy to read as English.

What should be included in a file header comment?

A good file header comment should fully describe the project and purpose of the code in the file.
