Core C++ A Software Engineering Approach

Classes

My next task is to describe the syntax for combining functions with data into an aggregate data type. C++ supports this by providing the struct and class keywords and the rules for merging components into an aggregate that can be handled as a whole. In the class definition, you specify the types and the names of the data members (data fields) and the headers or the bodies of member functions (that access these data fields).
