Simple case... but...
That's balls! =) Or if you are a girl, Great tits! =)
I mean, you need to keep up with these teaching... or learning. Expose C languange like you want in your veins... I had it, for 2 years... by force, and I can tell you, it was worse than philosophy. But worth the investment in learning.
I can tell you. If you like HPC, you have a job in that area with C knowledge. Also, who knows C knows C++ very easily, and other language. That's just because of the things you need to understand when you learn C.
Myself, I am in a deeper layer of the pyramid, but I know more than just C, because I need to troubleshoot more things that just the logic part of computing.
