Just like C use the sizeof operator...

cout << "sizeof (int) is " << sizeof (int) << " bytes.\n";

If you are using sizeof with a type enclose the type in parentheses. If
you are using sizeof with a variable name the parentheses are optional.

It always happens that way. Right after you get good at something some
"expert" will come a long and decide it is obsolete. :-/
