hi
c is a very good way to start, and it shouldnt be a problem at all to get familiar with this. After this course i suggest you get in touch with C++, because of the fact that C is the basis for it and so it wont be hard for ya to learn C++.
btt: C++ what to expect:
well, C++ supports you with modern paradigms which allow approaches for many different kind of problems. You cant do anything wrong by learning this language ;-)
It is a very good choice.
My two cents
Happy coding & o/
