Is there any situation where you should use C instead of C++?

Question

See Question.

Answer 1

Mainly if you need to write a program into embedded device like microcontrolers or mircoprocesors.Devices without its own operation systems.Lots of portable projects are written in strict ansi C.

Answer 2

C's standard library takes up less memory, and it also doesnt require a runtime library to run like c++ does. Which makes it ideal over c++ for microcontrollers/embedded systems/drivers.

Answer 3

C is less bloated than C++. If your project requires strict optimization for any reason, C could be better.
