Introduction to C++ Operator Overloading - Computer Action Team
Overloading operators as non-member functions is like defining regular C++ functions Since they are not part of a class' definition they can only access the public members Because of this non-member overloaded operators are often declared to be friends of the class

How to overload an operator in C++?
- The following is an example of how you can overload an assignment operator in C++. You can overload the function call operator on any object in the class. When you overload the function operator, you create a new way to call the function and create a new operator function using which you can pass numerous arbitrary parameters.
How to overload a binary operator for user-defined types?
- Here, + is a binary operator that works on the operands num and 9. When we overload the binary operator for user-defined types by using the code: The operator function is called using the obj1 object and obj2 is passed as an argument to the function. Instead of this, we also could have written this function like:
How many times can a function call operator be overloaded?
- In fact, the function call operator may be overloaded several times within the same scope with a different number (and/or type) of arguments. ?It is useful for accessing elements from a multi- dimensional array: matrix (row, col) where the [] operator cannot help out as it takes 2 operands always, never 3!
What operators can be used in prefix and postfix form?
- ?Two other operators that are useful are the increment and decrement operators (++ and --). ?Remember these operators can be used in both the prefix and postfix form, and have very different meanings. ?In the prefix form, the residual value is the post incremented or post decremented value.
