The question is ambiguous, since there are many types of operators.
Telephone service - The original purpose of a telephone operator was to connect calls. Now, that is mostly automated and operators are only there if there are problems or assistance is needed.
Computer logic - Boolean functions (or operators) such as AND, OR, NOR, XOR, NOT, NAND, etc. are used to toggle individual bits, perform calculations, etc.
Computer user - Most computers need someone to operate them.
Operators and Operator Functions : An operator functionimplements a particular operator symbol. The database server provides special SQL-invoked functions, called operator functions, that implement operators. An operator function processes one to three arguments and returns a value. When an SQL statement contains an operator, the database server automatically invokes the associated operator function. The association between an operator and an operator function is called operator binding. You can overload an operator function to provide the operator for a UDT. The SQL user can then use the operator with the UDT as well as with the built-in data types. When an SQL statement contains an operator, the database server automatically invokes the associated operator function.

Why a friend function cannot be used to overload the assignment operator?
Assignment(=) operator is a special operator that will be provided by the constructor to the class when programmer has not provided(overloaded) as member of the class.(like copy constructor). When programmer is overloading = operator using friend function, two = operations will exists: 1) compiler is providing = operator 2) programmer is providing(overloading) = operator by friend function. Then simply ambiguity will be created and compiler will gives error. Its compilation error.
In SQL what is the function of the union operator?
In SQL, the function of the union operator is to combine the result of two or more select-statements. The union operator is a very useful tool when coding SQL.
Definition of operator overloading inc plus plus?
to define an additional task to an operator ,we must specify what it means in relation to the class to which the operator is applied.this is done with the help of a special function called operator function ,which describes the task.
How operator overloading differ from function overloading?
Function overloading is multiple definition with different signatures(the parameters should be different) for the same function. The parameter list have to be different in each definition. The compiler will not accept if the return type alone is changed. Operator overloading is defining a function for a particular operator. The operator loading function can not be overloaded through function overloading.
Is it possible to do operator overloading in c?
No. Operator and/or function overloading is only a C++ thing.
Which operator require to call c function using object name?
The operator required to call c function using object name is function object. Other operator names that deal with objects are structure dereference, structure reference, and indirection
How do you add two numbers with out using operator in c language?
Not possible. Of course you can call a function which does the addition for you, but function-calling is also an operator in C.
How do you define power function without using operator?
using pow() function.. ..

Which operator will be used first in c?
