Because, the program you are creating requires the 'types' headers?

What program are you talking about? What are you trying to accomplish.

What do you really want to know?

header files

1. That line is at the start of the program, and is used by the preprocessor
2. 'include' means to take the following header file (.h file) and insert its contents before your main code before compiling.
3. The header file contains code which sets up one or more functions. If a tutorial is asking you to write that line, it will be using a function later on that is prepared in the header file just mentioned.
