Overloading operator

[Rasha Altoumaimi]

hello everyone!
I have question about overloading operator. actually I am confused about the answer this question.
True or false, you can change the behavior of the operator - or + for using int type using operator overloading

You can overload operators only if at least one operand is of user defined type.
That means you can overload operator-(int, foo), but cannot operator-(int, int)
