Navigating C++ and Object-Oriented Design

7.6. Key Point Summary

• A class design boilerplate helps you create consistent classes.

• Initialization calls constructors. Assignment calls operator functions.

• Classes with nonstatic constant data members generate compilation errors for default assignment. The compiler uses default memberwise copies if you do not overload assignment. Overloaded operator=() must be a nonstatic class member function.

• All overloaded operators are inherited except operator=().

• Always overload operators in classes that require them, especially if conversion rules produce legal (but incorrect) expressions with overloaded cast operators.

• Overloading iostream operators (<< and >>) for class objects must use nonmember functions.

• A class may grant a friend function access to ...
