What is diffrent between unary and binary opration?dbms?

What are the unary operations in Relational Algebra?

well vinay!A mathematical operation, such as the square root function and complex conjugation, that requires only one operand....unary operations in Relational Algebra are :PROJECTION and SELECTION

expalin the concep of overloading unary operators ?

Well You can overload a unary operator with either a nonstatic member function that has no parameters, or a nonmember function that has one parameter. Suppose a unary operator is called would have the following form:returntype operatorTAn overloaded unary operator may return any type.The following example overloads the ! operator: In Cinclude <iostream>using namespace std; struct

how unary operators prcessed in c?

unary operator require only a single expression to produce a line.unary operators usually precde their single operand.the most common unary operation is unary minus.

Why is the bash builtin test slightly different from /bin/test??

of rules for processing test arguments. 0 Args: False 1 Arg: True iff argument is not null. 2 Args: If first arg is !, True iff second argument is null. If first argument is unary, then true if unary test is not null. 2 Args: If first arg is !, True iff second argument is null. If first argument is unary, then true if unary test is true Otherwise error. 3 Args: If second argument is a binary operator, do binary

What arithmetic operations are supported in JavaScript?

JavaScript supports the following arithmetic operations which you can group in brackets to form more complex expressions: unary operations binary operations shifts mathematical functions Unary...JavaScript supports the following arithmetic operations which you can group in brackets to form more complex expressions: unary operations binary operations shifts mathematical functions Unary operations have one

Explain with example operator ovaerloading.

of an operator; for example, you cannot define plus to have three operands.Some operators are unary have one operand, and some are binary have two operands. The example given above includes only binary operators: =, , , [...], and ==. Examples of unary operators are: unary minus, pre- and post-increment, and pre- and post-decrement.Unary operators, and binary operators whose left operands are class objects, can be defined either as member

what is Pointers and how to declared inline fuction

that we want to store in ptr the address of our integer variable k. To do this we use the unary & operator and write:ptr = &k;What the & operator does is retrieve the lvalue address of k, even variable which contains the address in memory of another variable. We can have a pointer to any variable type.The unary or monadic operator & gives the address of a variable.The indirection

What is Pointer?

have a pointer to any variable type.The unary or monadic operator & gives the address of a variable.The indirection or dereference operator gives the contents of an object pointed to by a pointer is in its use of pointers.What is a Pointer------>A pointer is a variable which contains the address in memory of another variable. We can have a pointer to any variable type.The unary or monadic operator

What is FAFLfinite automata and formal languages all about??... What is the use of studying it??...

-deterministic automata have been studied. 2 Subdirect decompositions of finite automata and unary algebras. The subdirectly irreducible members of some varieties of finite automata have been characterised. On the other hand, subdirect decompositions of general unary algebras have been considered in terms of some notions, such as cores and Rees congruences, originating mostly in semigroup theory. This work has been done

define pointer and arrays....???

to any variable type. The unary or monadic operator & gives the address of a variable. The indirection or dereference operator gives the contents of an object pointed to by a pointer. To declare a to any variable type.The unary or monadic operator & gives the address of a variable.The indirection or dereference operator gives the contents of an object pointed to by a pointer.To declare a

How-to to add to values in java core without using plus operator?

, their coverage is brief; the intent is to simply make you aware that these operators exist.The unary bitwise complement operator "" inverts a bit pattern; it can be applied to any of the integral types

What does exactly p mean in C language?

hai,p means post increment...In general, the postfix and -- operators essentially have higher precedence than the prefix unary operators. Therefore, p is equivalent to p; it increments p, and returns

Operator Overloading in Vb?

intuitive and more readable code. The operators that can be defined on your class or structure are as follows: Unary operators: - Not IsTrue IsFalse CType Binary operators: - / & Like Mod And Or Xor
