Answer the following statements true (T) or false (F)

Question

1. When an operator is overloaded as a member of a class, the first parameter listed in parentheses, is the calling object.
2. If a unary operator is overloaded as a stand-alone function, the argument may be any type.
3. Overloading an operator cannot change the precedence of that operator with respect to other operators.
4. If I need to build an object for return from a function, I can construct that function directly in the return statement.

Answer 1

1. False
This is backwards. The calling object is the first argument.
2. False
All overloaded operator functions must have at least one class type argument or be a member of a class. In the case of a unary operator, if it is overloaded as a member, there is no argument, there the class type calling object is the argument. If overloaded as a friend, there is one argument.
3. True
4. True
Given class A, which has a two int constructor, A(int, int). If I have a function, that needs to build a return object, it can be done by creating an anonymous A object directly in the return statement.
```
A func( int arg)
{
return A(arg, 2*arg);
}
```
