Give me the answer Difference between unary and binary operator?

A unary operator is one which operates on just one number, e.g. x2 or -x.
A binary operator is one which takes two numbers, e.g. x + y or xy.
Note that this has nothing to do with binary vs. decimal arithmetic.
This term is commonly used to distinguish between the two buttons which have a '-' sign on a calculator. The unary '-' operator button is used to change the sign of a number entered, and the binary '-' operator button is used to subtract two numbers, which is quite a different thing. The unary '-' button is commonly labelled '+/-'.

What is the difference between unary and binary?
In programming a unary and binary operator defines how many components make up an expression.
What is difference between binary and unary operator in c language?
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.
What is plus operator is it unary or binary?
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 */
What is unary mening?
'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.
What is unary minus operator?
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)

Explain the Difference between bitwise operator ' and ' and address operator ' and ' of pointer?
The bitwise logical operator and (&) calculates the bitwise logical and of two integral values. It is a binary operator.The address of (&) operator returns the address of the value to its right. It is a unary operator.The distinction between the two is one of context. The logical and operator will follow (and be preceeded by) a value, while the address of operator will follow an operator.
Different operations done using rdbms?
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
What is difference between conditional operator and bitwise operator?
A binary operator is simply an operator that has two parts, written to the left and to the right of the operator, e.g.:1 + 2The binary operator can be a logical operator ("and", "or", "xor", etc. - but "not" is a unary operator), or it can be in some other category, like the arithmetic operator shown above.A binary operator is simply an operator that has two parts, written to the left and to the right of the operator, e.g.:1 + 2The binary operator can be a logical operator ("and", "or", "xor", etc. - but "not" is a unary operator), or it can be in some other category, like the arithmetic operator shown above.A binary operator is simply an operator that has two parts, written to the left and to the right of the operator, e.g.:1 + 2The binary operator can be a logical operator ("and", "or", "xor", etc. - but "not" is a unary operator), or it can be in some other category, like the arithmetic operator shown above.A binary operator is simply an operator that has two parts, written to the left and to the right of the operator, e.g.:1 + 2The binary operator can be a logical operator ("and", "or", "xor", etc. - but "not" is a unary operator), or it can be in some other category, like the arithmetic operator shown above.
Does a unary expression consists of only one operand with no operator?
No, a unary expression consists of one operand and one operator
What operator is a unary operator as it works with only one operand?
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.
Distinguish between operator overloading and function overloading?
in C++ there is no real difference as operators are overloaded by implementing them as functions. However, while we differentiate between function overloads by the function signature (the number and type of parameters), operator overloads are distinguished only by the parameter types. The parameters are interpreted as operands, and the number of operands will depend upon whether the operator is unary, binary or ternary. That is, for any given operator, the number of operands will be the same for each overload you implement. The only exceptions are the unary increment (++) and decrement (--) operators as they each have postfix and prefix variants. In order to differentiate their signatures, an unreferenced or dummy parameter must be passed to the postfix variants.
