Here is the situation. It is legal to use a plus operator on
boolean. The C/C++ concept is called "type promotion". The rules are
complicated but intuitively, if the type is smaller, it is promoted to
integer. So if we have:

	bool i=true, j = false

	the expression
         i+j

is of type integer and its value is 1.

Good luck to everyone on tomorrow's midterm.
