C++: OOP: Data member initializers
Initializing data members
There are two ways to initialize data members.
- Explicit assignments in a constructor.
- In a member initializer in the constructor header.
Member initializer syntax
The definition (not the prototype) header is followed by
a colon, the name of the field, and a parenthesized initial value.
Separate multiple initializations with commas.
Insert example here
Member initializer required in the following cases
- To initialize
const data members.
- To initialize references.
- To initialize member objects. If a member initializer is not
provided, the default constructor for that class will be called.
- To initialize base class members.
