C++ classes

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The C++ programming language allows programmers to separate program-specific datatypes through the use of classes. Instances of these datatypes are known as objects and can contain member variables, constants, member functions, and overloaded operators defined by the programmer. Syntactically, classes are extensions of the C struct, which cannot contain functions or overloaded operators.
