The object oriented approach is revolutionising the software development process. C++ is a powerful object oriented programming language which inherits many of its features from the ever popular C. This book introduces the fundamental principles of the object oriented model and demonstrates how to apply them to C++ programs. The topics covered include: basic language features: data structures, operators and expressions, programming and logarithms, function calls, indirection using pointers and references; object oriented design: separating implementation from interface, encapsulation and polymorphism; classes and objects: object constructors and destructors, protection keywords, class functions and friend functions; software reusability: templates, inheritance, class libraries and software components; advanced language features: dynamic objects and memory management, overloading functions and operators, virtual functions, structured error handling using exceptions.
