The history of C++ begins with C. The reason for this is easy to understand: C++ is built upon the foundation of C. Thus, C++ is a superset of C. C++ expanded and enhanced the C language to support object-oriented programming (which is described later in this module). C++ also added several other improvements to the C language, including an extended set of library routines. However, much of the spirit and flavor of C++ is directly inherited from C. Therefore, to fully understand and appreciate C++, you need to understand the “how and why” behind C.
C: The Beginning of the Modern Age of Programming
The invention of C defines the beginning of the modern age of programming. Its impact should not be underestimated because it fundamentally changed the way programming was approached and thought about. Its design philosophy and syntax have influenced every major language since. C was one of the major, revolutionary forces in computing.
