I don't know how many questions I actually have on the subject, but I guess that we'll find out as I type this out. I have experience in C++, I did in Java but remember very little, and have dabbled in Python and Ruby. I like C++ and I have been looking at job postings at big companies to see just what I need to know. Most say experience in C/C++, so I was wondering if I should work my way up from C to C++, shouldn't be hard seeing how they have the same workings. Or should I just continue with C++ and then learn C later on? Also how much do you usually need to know before you can say that you know a programming language. I don't need any websites or book recommendations because I have books on both C and C++. So just post your comments, thanks.
