C++ and C share a common syntax for defining expressions and instructions. We'll present it briefly here, highlighting the few differences between the two languages. Operators have priorities that specify the order in which the sub-expressions making up an expression should be evaluated.

In C++, operators can be prefixed, i.e. placed...
