How can you create a new operator through operator overloading?

You cannot create a new operator through operator overloading. You can only redefine an existing operator, with certain limitations. As an example, for a class of complex numbers, having a real and an imaginary part, you might want an addition operator. This is the skeleton of code to do that. I only show the operator, not any constructors or other operators or methods, etc.
class complex {
private:
double real, imaginary;
public:
complex operator+ (complex operand) {
complex temp;
temp.real = this.real + operand.real;
temp.imaginary = this.imaginary + operand.imaginary;
return temp;
}
};
The above answer is for C++. Since this question is also categorized in Java Programming it's important to note that operator overloading is not currently possible in Java.

How can you can create a new operator through operator overloading?
You cannot create any new operators in C++. You can only overload the existing ones (although some, such as sizeof, new and delete cannot be overloaded). The only way to create a new operator is to implement it as a standard function with a named identifier. For instance, sqrt() is the standard library function that provides the square root operator, for which no real operator exists.
Difference between new operator and operator new?
new operator allows to allocate a memory from the heap..... so a new instance of a class is created.......... but operator new is used to overload the (new) operator........ juast like overloading of other operators
Why use new and delete operator overloading in c plus plus?
one reason to use new and delete operator overloading in c++ is when you are using your own memory manager code. when the user of your code calls the new keywork, your memory manager code can allocate memory.
What is operator overloading?
I think you mean operation overlord??? It is the American, Canadian and British offensive on Europe in World War 2. They landed in Normandy on 6th June 1944 (Commonly called D-Day, Day of Days or Deliverance Day) and progressed throughout France liberating Paris on the 25th August. This allowed the allies a foothold in Europe.
What is the use of new operator?
A new operater is used to allocating a memory space for a particular object.
Why do you use of operator overloading in c?
Overloading, Overriding, Polymorphism, Information Hiding, Inheritance all these are CONCEPTS of C++ and Java. An Object Oriented Language and not of C language. Thats why Bjarne Stroustrup came up with C++ ...
What does the java new operator do?
The new keyword tells Java that you want to create a new instance of a class by invoking one of the constructors for that class.// Create a new, empty String objectString s1 = new String();// Create a new String object with a different constructorString s2 = new String("howdy");
How operator overloading is useful in class based programming?
The concept of Operator Overloading is similar to Method Overloading, in that the meaning of a given operator symbol changes according to the context it is being used in. That is, the semantics of the operator symbol are flexible, rather than fixed.The idea behind Operator Overloading is to take a common symbol, and adjust it's meaning to something logical for contexts other than what it was originally restricted to.The arithmetic operators ( + - * / ) are good examples. Using Operator Overloading, I could define that 'SomeArray + SomeValue' means that I should add SomeValue to the end of the array SomeArray.In general, Operator Overloading is what is called 'syntactic sugar' - it makes things more readable. For instance, the equivalent way to do the above example via method calls would be: SomeArray.addToEnd(SomeValue)The major problem with Operator Overloading is that it depends on people having the exact same interpretation of what an operator would mean in the new context, which is difficult to assure. Going back to the above example, there is some ambiguity as to where 'SomeArray + SomeValue' would mean to add in SomeValue - should SomeValue be added to the start of the array, or the end of the array? The answer is not obvious, and one would have to go look through the overload definition. While this confusion is also possible with methods, properly named methods (i.e. using addToEnd() rather than just add() ) helps avoid this entirely.For this reason, Java does not support user-defined Operator Overloading. Java does support certain operator overloading in narrow contexts, but only those defined by the language itself. That is, the '+' sign is overloaded to allow for string concatenation. However, the designer of Java (James Gosling) decided that his preference was to avoid Operator Overloading completely due to his perception of a "clean" language.
How the new operator works in java?
1. It is the only way to create object. 2. New is a keyword. 3. New operator allocates memory for an object. 4. It is a bit faster and clever way of creating objects or instances.
How do you be a professional telephone operator?

What is the method of creating new technology?
We create new technology through the use of engineering.
What is the difference between over-loading and over-riding in cpp?
Overloading and overriding do similar things but they are distinct. When you override a function, you are providing a new implementation of a function that was inherited from a base class. The signature of an override must be covariant with the base class signature. Overloading means to create several functions with the same name within the same namespace but with different signatures.
