'not' for instance is a unary operator. It is unary in the sense that it operates on a single item. In contrast a binary operator such as addition operates on two items.

Unary RelationshipsUnary relationships have only one participant-the relation is associated with itself. The classic example of a unary relationship is Employee to Manager. One's manager is, in most cases, also an employee with a manager of his or her own.

The nnary and Binary operators in relational Algebra.

In most contexts, operations are functions. A function is a relationship between an input set (1 or more) and potential output. An operation is usually said to be unary (1 input. For example: negative, square, square root, or factorial) or binary (2 inputs. For example: add, subtract, multiply, divide, or modulo). Typically the term operation is reserved for calculations that are axiomatic, whereas functions are composites of operations. In computer programming languages the distinction is typically only symbolic.

It is a number system with the base 1, so for example 1 would be represented with |, 2 with , 5 with | etc.

An additive function is a unary function which preserves the addition operation.

UNARY AND BINARY a unary operation is an operation with only one operand, i.e. an operation with a single input, or in other words, a function of one variable. eg- * Increment: ++x, x++ * Decrement: −−x, x−− * Address: &x * Indirection: *x * Positive: +x * Negative: −x * One's complement: ~x * Logical negation: !x * Sizeof: sizeof x, sizeof(type-name) * Cast: (type-name) cast-expression int i = 0; printf (" %d \n %d ", i++, i++); a binary operation is a calculation involving two operands.

There is no unary plus in C, but if there were, it would have only one operand, unlike the binary plus which has two: x = a + b; /* binary plus */ x = + b; /* unary plus -- not in C*/ x = a - b; /* unary plus */ x = - b; /* unary minus */

No. The subtraction operator is a binary operator that returns the result of subtracting the rhs operand from the lhs operand. The unary minus operator simply negates the rhs operand. int x = -5; // unary minus. x is (-5) int y = -x; // unary minus. y is (+5) y -= x; // binary minus/assign operator. y is (+10) --x; // unary decrement operator. x is (-6) y -= (-x); // binary minus/assign and unary minus operators. y is(+4)

In programming a unary and binary operator defines how many components make up an expression.

No, a unary expression consists of one operand and one operator

The number of arguments will be one for the unary operators and two for the binary operators. In the case of unary operators, the argument must be of the same type as that of the enclosing class or structure.

Yes, a unary operator is an operator that only has one operand. Examples of unary operators are negative (-), positive (+), increment (++), decrement (--), address of (&), dereference (*), logical not (!), sizeof, one's complement (~), new, and delete.
