&) and dereference (
*), act on one operand. Binary operators, such as equality (
==) and multiplication (
*), act on two operands. There is also one ternary operator that takes three operands, and one operator, function call, that takes an unlimited number of operands.
Some symbols, such as
*, are used as both a unary (dereference) and a binary (multiplication) operator. The context in which a symbol is used determines whether the symbol represents a unary or binary operator. The uses of such symbols are independent; it can be helpful ...
