Should you use C?
Most likely, you shouldn't use C. It is mostly falling out of use these days because it is outdated. However C still sees use in places like the Linux kernel. C is also being replaced by its younger brother, C++, which is similar to C with more features, but C is simpler to learn. However, if you are comfortable with a low level language with manual memory management and a small feauture set, C is right for you.
