What are unary and binary operators? Functions: If A and B are sets, afunctionf is a relation between A and B such that: For every a in A, there exists a b in B such that (a,b) is in f If (a,b) and (a,c) are in f, then b=c ...
a unary operator is an operator that operates on only one operand, unlike binary operators, which operate on two operands. it performs various operations on a single value, such as negating, incrementing, decrementing, or complementing it. unary operators are commonly used in programming languages...
