Q:

Vertical Bar: Symbolism

First of all, What should print to the screen if I do this:

cout << '\x7E';

What I'd like to know is what is the \x?? for the "|" symbol?

A:

You could have tried it.
As for the symbol, it's octal 174 or hex 7C:
cout << '\174';
cout << '\x7C';

You can find this stuff yourself if you search for "ascii table":

You can even work it out yourself:
int c = (int)'|';
cout << dec << c << endl;
cout << oct << c << endl;
cout << hex << c << endl;
