What does the “c” mean in cout, cin, cerr and clog?

Question

What does the "c" mean in the cout, cin, cerr and clog names?

I would say char but I haven\

Answer 1

I originally guessed console, and this link confirmed it. But after seeing the quote from Stroustrup, it seems that's a misconception, and that the c stands for character.

One thing in favor of that theory that can serve as an indicator is the fact that for each stream object (cin, cout, cerr, etc.) there is an equivalent, wide-stream one (wcin, wcout, wcerr, etc.).
