   • Operator Overloading in C++

     in C++, Operator overloading is a compile-time polymorphism. It is an idea of giving special meaning to an existing operator in C++ without changing its original meaning.

     In this article, we will further discuss about operator overloading in C++ with examples and see which operators we can or cannot overload in C++.

     C++ Operator OverloadingC++ has the ability to provide the operators with a special meaning for a data type, this ability is known as operator overloading. Operator overloading is a compile-time polymorphism. For example, we can overload an operator ‘+’ in a class like String so that we can concatenate two strings by just using +. Other example classes where arithmetic operators may be overloaded are Complex Numbers, Fractional Numbers, Big integers, etc.

     Example:

     int a; float b,sum; sum = a + b;

     Here, variables “a” and “b” are of types “int” and “float”, which are built-in data types. Hence the addition operator ‘+’ can easily add the contents of “a” and “b”. This is because the addition operator “+” is predefined to add variables of built-in data type only.

   • Operator Overloading in C++

      In C++, we can make operators work for user-defined classes.

Hence the addition operator ‘+’ can easily add the contents of “a” and “b”. This is because the addition operator “+” is predefined to add variables of built-in data type only. 

     Now, consider another exampleclass A{};int main(){      A   a1,a2,a3;      a3= a1 + a2;      return 0;}In this example, we have 3 variables “a1”, “a2”...

   What is function overloading & operator overloading in C++?

   • When the above code is compiled and executed, it produces the following result − C++ allows you to specify more than one definition for a function name or an operator in the same scope, which is called function overloading and operator overloading respectively.

   How to overload a binary operator?

   • To overload a binary operator, you must seek two arguments. You need to ensure that one of the operators should be of type class or struct where the operator is defined. As previously discussed, a binary operator cannot return void, but it can return all other types of values while implementing overloading.

   Does C++/WinRT overload the & operator?

   • C++/WinRT does not overload the & operator at all. _com_ptr_t, IPTR, and C++/WinRT do not provide a way to access the wrapped pointer’s address without freeing it. Comparison operators break only in _com_ptr_t. (Comparison operators never worked with IPTR, so there was nothing to break.)
