Separate Compilation

When your code gets large or you work in a team, you will want to split your code into separate source files.
- Saves time: instead of recompiling the entire program, only recompile files that have been changed.
- Group work: separate programmers work on separate files.
The header file (e.g. Product.h) contains:
- definitions of constants
- definitions of classes
- declarations of nonmember functions
- declarations of global variables
The source file (e.g. Product.cpp) contains
- definitions of member functions
- definitions of nonmember functions
- definitions of global variables
