Adding Different Types

Adding objects of different types

If the arguments are different, the functions are different. So overloading ...

ComplexNumber operator+( const ComplexNumber& obj1, int obj2)
ComplexNumber X;
X + 10;

But not

10 + X;

... since the left operand and the right operand don’t match the function prototype above. So we might define the following too...

ComplexNumber operator+(int obj2, const ComplexNumber& obj1)
