			Result = 14 / 4;

	d) Assignment operators have the highest order of precedence.

	e) Right to left is the default order of statement execution.

	f) The unary operators have a higher order of

	q) A valid C++ identifier is "300ZX".

	r) A valid C++ identifier is "mazda626".

	s) Dividing by zero is a common run-time error.

	t) Missing a semi-colon is a common compile-time error.
