C++ (pronounced cee plus plus) is a general purpose programming language developed by Bjarne Stroustrup starting in 1979 at Bell Labs. It is immensely popular, particularly for applications that require speed and/or access to some low-level features. It is considered to be an intermediate level language, as it encapsulates both high and low level language features.

C++ supports procedural, object-oriented, functional and generic programming. C++ runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX.

Key Benefits:

  • Type safety
    • Encapsulate necessary unsafe operations
  • Resource safety
    • Not all resource management is managing memory
  • Performance
    • For some parts of almost all systems, it's important
  • Predictability
    • For hard and soft real-time systems
  • Teachability
    • Complexity of code should be proportional to the complexity of the task
  • Readability
    • People and machines ("analyzability")
  • Direct map to hardware
    • of instructions and fundamental data types
  • Zero-overhead abstraction
    • Classes with constructors and destructors, inheritance, generic programming, functional programming techniques

The standard for C++ is maintained by the International Organization for Standardization (ISO), and the current version of C++ as of December 2014 is C++14 (named not as the 14th version of C++, but rather signifying that the standard was ratified in 2014).

The best thing about C++ is that it runs on everything from embedded processors with very limited resources to the largest mainframe supercomputer and every personal computer in between.
