What is C, What is C++, and What is the Difference?

C is a programming language originally developed for developing the Unix operating system. It is a High-level (also called Middle-level) and powerful language, but it lacks many modern and useful constructs. C++ is a newer language, based on C, that adds many more modern programming language features that make it easier to program than C.

Basically, C++ maintains all aspects of the C language, while providing new features to programmers that make it easier to write useful and sophisticated programs. 

For example, C++ makes it easier to manage memory and adds several features to allow "object-oriented" programming and "generic" programming. Basically, it makes it easier for programmers to stop thinking about the nitty-gritty details of how the machine works and think about the problems they are trying to solve.

So, what is C++ used for?

C++ is a powerful general-purpose programming language. It can be used to create small programs or large applications. It can be used to make CGI scripts or console-only DOS programs. C++ allows you to create programs to do almost anything you need to do. The creator of C++, Bjarne Stroustrup, has put together a partial list of applications written in C++.
