C++: Declaration of a class

A class is defined in C++ using the keyword class followed by the name of the class.

Declaration of a class

 

A class is defined in C++ using the keyword class followed by the name of the class. The body of the class is defined inside the curly brackets and terminated either by a semicolon or a list of declarations at the end.

The only difference between structure and class is the members of structure are by default public where as it is private in class.

 

The General Form of a class definition

{

private:

      variable declaration;

      function declaration;

protected:

      variable declaration;

      function declaration;

public:

};

• The class body contains the declaration of its members (Data member and Member functions).
