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 */
The plus operator is a unary operator. Essentially it removes the sign of its operand. The add operator is a binary operator, returning the sum of its operands.
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)
An operand is the value that is being operated upon by an operator. For instance, the C++ increment operator (++) is a unary operator, which means it has only one operand, the variable that we wish to increment. This in the expression x++, x is the operand. The addition operator (+) is a binary operator and therefore has two operands. Thus in the expression x + y, x and y are the operands.
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.
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.
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.
'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.
In programming a unary and binary operator defines how many components make up an expression.
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)

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 '+/-'.
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.

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.

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