Balance Example

This program illustrates splitting declarations from definitions, especially for classes and named constants.

dollar.h
- Note the use of extern const to declare CENTS_PER_DOLLAR. It has just one definition in dollar.cpp but the declaration allows it to be used in any file that includes dollar.h.
dollar.cpp
balance.cpp

To build, download makefile and type

        make

It will also build in the old-fashioned way

        g++ -std=c++11

but the nice thing about the makefile is that if you edit one of the sources the minimum number of files are recompiled.
