C++ is a programming language developed by Bell Labs in 1983 and based on the C programming language. C++ is an object-oriented mid-level programming language. It has support for multiple inheritance, operator overloading, templates and exception handling.
C++ is widely used for large projects where both the power of low-level programming (for execution speed) and high-level object oriented programming (for development speed) is needed.
Some find C++ hard to learn and mistakes are easily made by the novice programmer. Languages such as Java and C# are derived from C++ and try to make the job a bit easier for the programmer. However, these languages lack the execution speed and some of the advanced features of C++.
C++ "hello world" example:
std::cout << "Hello World!" << std::endl;
