4. Expressions and instructions
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. Furthermore, to force an evaluation order, it is always possible to group expressions by pairs of parentheses.
4.1 Expressions
Expressions are made up of operations. Evaluating an expression produces a value. An operation is a treatment to be applied to the operands. There are several types of operator, depending on the number of operands they accept (unary operators expect one operand, binary operators expect two operands, etc.). In C++, operators can be prefixed, i.e. placed...
