Study Notes
C++ Programming and Classes
- The main purpose of C++ programming is to add object-oriented features to the C programming language.
- Classes are the central feature of C++ that supports object-oriented programming and are often called user-defined types.
Class Definition
- A class definition specifies the form of an object and combines data representation and methods for manipulating that data into one package.
- The data and functions within a class are called members of the class.
- A class definition starts with the keyword "class" followed by the class name and the class body, enclosed by a pair of curly braces.
- A class definition must be followed by either a semicolon or a list of declarations.
Class Members
- The keyword "public" determines the access attributes of the members of the class that follows it.
- A public member can be accessed from outside the class anywhere within the scope of the class object.
- Members of a class can also be specified as private or protected.
Defining C++ Objects
- A class provides the blueprints for objects.
- An object is created from a class, and objects of a class are declared with exactly the same sort of declaration as variables of basic types.
- Each object of a class has its own copy of data members.
Accessing Data Members
- The public data members of objects of a class can be accessed using the direct member access operator (.).
- The direct member access operator is used to access the data members of an object.
