So I might be getting a job using C and I have a week to study it.
I said in my first interview I have a year experience in C even though I don't
I said this because I've programmed using C++, C#, Java and SQL for 4-5 years so I figured it wouldn't be that different.
Sure enough in the first interview I knew the answer to all their questions since most of it bled in from other languages (except some of the stock market ones, has to do with the job). So I'm not too worried.
But just in case I get blindsided by something I want to make sure I'm fully prepared and don't jeopardize anything, especially since its a small team and what they do is a big deal.
What would be a program that I could learn/write that would fill the gaps of what I don't already know with C, in other words, what it would be used for more often than C++ or C#?
