If a C++ class have multiple member functions, having same name but different parameters (with change in type, sequence or number), and programmers can use them to perform similar form of operations, then it is known as function overloading.
One of the features of object oriented programming is Data abstraction.
Encapsulation can be defined as the process of hiding all of the details of an object that do not throw in or dealt with its essential characteristics. Encapsulation can also be defined as preventing access to non-essential details of classes or its objects.
Polymorphism is another concept of object oriented programming (OOPs). The attitude which lies beneath this concept is “single interface having multiple implementations.” This provides a single interface for controlling access to a general class of actions
Qualifiers and storage class are smaller but important programming concept that helps to make the quality of a variable more accurate for using that variable within the program. In this chapter you will learn about how qualifiers are used with variables and what the roles of different storage classes in C++ are.
Classes of C++ can be reuse is several ways. One of them is the concept of Inheritance.
In C++ a function or an entire class may be declared to be a friend of another class or function. Friend function can also be used for function overloading.
A virtual function is a special form of member function that is declared within a base class and redefined by a derived class.
In this chapter you will learn about how to dynamically allocate memory within a C++ program.
