The class is a new keyword intr

oduced in C++. It is used in the same way as the struct keyword.

To declare a class, the following syntax is used:

Syntax:

<classkeyword> <class- name> [<:baseclasslist>]

{<member variable list>}

Class keyword: It is one of the keywords class, struct, or union.

Class-name: It can be any unique name inside its scope.

Baseclasslist: If the class is derived class, then it follows the list of the base class (es). It is optional.

Member variable list: Defines the data member variables and member functions.

{

int radius; // data member

int area (void); // member function ...
