C++ Programming Language Superset of C Language, i.e., Contains the whole C Language Structured but Not Structured because of GOTO statement cin for Input or cout for Output Statements Huge Library of Functions at Run Time (C & C++) C Compiler can Compile a C++ Compiler Compilers for Other Programming Languages can be Written in C++ Language Fully Supports both Functional and Object Oriented Programming Paradigms Developed By Bjarne Stroustrup (59, alive) in 1983

C++ Programming Language, ... One of the Most Popular Programming Languages ever Created C++ is widely used in the Software Industry. Systems Software, Application Software, Device Drivers, High Performance Server and client Applications, Embedded Software, Entertainment Software such as Video Games Several Groups Provide both Free and Proprietary C++ compiler software, including the GNU Project, Microsoft, Intel and Borland C++ has Greatly Influenced many other Popular Programming Languages, most notably Java
