C Problems and Solutions [closed]

Question

I'm looking for a series of C problems (with solutions) that I can use to build my C skills. I already understand the basics of the language, the syntax, and the semantics. I am looking for a series of problems that will help me hone my skills, not a set of simple questions that you'd see in an introductory programming class.

Answer 1

You might try solving some of the problems on Project Euler. The first few are pretty simple, but they get very challenging very quickly. I think it's a lot of fun trying to come up with the shortest code or highly optimized code to compute the results (though, I generally use C++ or Python, not C).

One advantage the Project Euler problems have is that they aren't just language-centric; they're problems that really make you think hard about how to develop an elegant solution to difficult problems.

Answer 2

And don't forget code-golf.

You probably want to respond only to challenges (questions) that have at least 10 upvotes.
