During this hour, you were shown how C++ evolved from other styles of computer languages and embraced a methodology called object-oriented programming. This methodology has been so successful in the world of computing that the language remains as contemporary today as it did when it was invented in 1979.
I wish the mullet haircut I sported in college had survived the test of time as well. Instead, it lives on in Facebook photos that friends share to shock and awe.
In the two programs that you developed during this hour, you made use of three parts of a C++ program: preprocessor directives, comments, and functions.
All the programs that you will create in C++ employ the same basic framework as the Motto and Calculator programs. They just become more sophisticated as they make use of more functions, whether you write them from scratch or call functions from header files included with the #include directive.
