These features enable creating of abstract data types inherit properties from existing data types and support polymorphism, thereby making C+, , truly object-oriented language. | ¥ (the object-oriented features in C++ allow programmers to build large programs with clarity, extensibility and ease of maintenancé)incorporating the spirit and efficiency of C The addition of new features has transformed C from a language that currently facilitate top-down, structured design, to one that provides bottom-up, object-oriented design. C++ is a versatile language for handling very large programs. It is suitable for virtually any programming task including development of editors, compilers, databases, communication systems and any complex real-life application systems. @ Since C++ allows us to create hierarchy-related objects, we can buildspecial object- oriented libraries which can be used later by many programmers. © While C++ is able to map the real-world problem properly, the C part of C++ gives the language the ability to get close to the machine-level details. © C++ programs are easily maintainable and expandable. When a new feature need: to be implemented, it is very easy to add to the existing structure of an object, © It is expected that C++ will replace C as a general-purpose language in the near future. + Letus begin with a simple example of a C++ program that prints a string on the screen. demonstrates several C++features.it the default return and return will run. type for all functions i i ee eS C++ is int.
