C vs C++?

Question

What is the purpose of using C over C++ and vice-versa?

If C++ is considered the 'upgraded' version of C, then what's the point of using the C language at all if C++ can do everything and more that C can do?

Answer 1

With the power of Google I found this:
C is a much smaller, simpler language. It's easier to know it well, and find other programmers who know it well. It hasn't changed very much in 30 years. There's less that can happen under the hood, the low-level characteristics of C code are generally very obvious. Its limitations are usually tolerable for problem domain it was designed for. The compile times for heavy-duty C++ code can be a huge pain in the ass.

Answer 2

C++ is well-rounded in terms of platforms and target applications, so if your project is focused on extremely low-level processing, then you may want to use C++. C++ is often used for large-scale, multi-man, complex projects where separate people need to work on modularised components.
