How to implement operator overloading C++

Operator overloading can be implemented in two ways. They are: Using a member function Using a friend function   Differences between using a member function and a friend function to implement operator overloading are as follows: Overloading Unary Operators Operators which work on a single operand are known as unary operators. Examples are: increment operator(++), decrement operator(–), unary minus operator(-), logical not operator(!) etc. Using a member function to overload an unary operator Following program demonstrates overloading unary minus operator using a member function: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
