Are overloaded operators member functions?
Are overloaded operators member functions?
You also learned you can overload operators as normal functions. Many operators can be overloaded in a different way: as a member function. Overloading operators using a member function is very similar to overloading operators using a friend function.
Which operators are always overloaded as member functions?
Operators which can be overloaded either as members or as non-members. This is the bulk of the operators: The pre- and post-increment/-decrement operator++() , operator–() , operator++(int) , operator–(int) The [unary] dereference operator*()
What is member function overloading?
Function Overloading in C++ can be defined as the process of having two or more member functions of a class with the same name, but different in parameters.

What are the rules of overloading operators?

- Only Existing operators can be overloaded.
- The overloaded operator must have at least one operand is of user defined type.

What does it mean to overload an operator in C + +?
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.
Can a non-member function be an overloaded operator?
Most overloaded operators may be defined as ordinary non-member functions or as class member functions. In case we define above function as non-member function of a class then we would have to pass two arguments for each operand as follows − Following is the example to show the concept of operator over loading using a member function.
What happens when you call an overloaded function in Java?
When you call an overloaded function or operator, the compiler determines the most appropriate definition to use, by comparing the argument types you have used to call the function or operator with the parameter types specified in the definitions.
