I am a big fan of C, have many worn copies of Kerninghan and Ritchie.  I really like C because if what you want to do does not exist... You just write it.

C gives you that kind of control, but of course your memory management needs to be perfect.

I started my career programming in C, so still love it, and still use it.

There are some examples here in c, and I do the same examples using c++ in the other section.
