'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.
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 */
different rdbms operations are delete,update easily and other u find on some other site. •Insert : unary operation •Delete : unary operation •Update : unary operation •Select : unary operation •Project : unary operation •Join : binary operation •Union : binary operation •Intersection : binary operation •Difference : binary operation
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.
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.

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.
In mathematics, unary operations are functions having only one number for an input. These include functions such as finding squares, square roots, and reciprocals for a number.
A binary function would be one with two parameters, a unary, one with one parameter.However, these words are usually used for operators. For example, the common arithmetic operators, +, -, *, /, % are binary - they need two operands, for example, "2 + 3". The minus sign can also be unary; -x is the additive inverse of x. Unary means one operand is required. Boolean operators for and, or, xor, are binary. Actually, the great majority of operators are binary.
