(Data Members) Explain the purpose of a data member.
Solution:
A class normally consists of one or more member functions that manipulate the attributes that belong to a particular object of the class. Attributes are represented as variables in a class definition. Such variables are called data members and are declared inside a class definition but outside the bodies of the class’s member-function definitions. Each object of a class maintains its own copy of its attributes in memory. These attributes exist throughout the life of the object. The example in this section demonstrates a GradeBook class that contains a courseName data member to represent a particular GradeBook object’s course name.
