12.10    Interim Recap

We’ve covered a lot of ground so far in this chapter. Before we dive deeper into how to make usage of your own data types, let’s take a breather and recall the key lessons learned so far:

• Use struct to create new types.

• Global functions can operate on parameters of the new type and return the new type as a result.

• Methods keep data and functions together.

• Avoid using global variables directly in functions and methods.

• You can define operator<<(ostream&,…) and use it to output your type.

• Separate the declaration and definition of methods by splitting them into header and implementation files.

• Divide your type into private and public sections using public and private.

• Use struct or class to clarify your intention ...
