Overloading '=', getting errors

Anything wrong with this overloading

Code:

---

TankStatus operator=(int number, TankStatus ts)
{
        return ts = number;
}

//: error C2801: 'operator =' must be a non-static member

---

TankStatus is enum type....

You can only overload operators on classes, structs and unions. MSDN explains that if you look up the error number. Why would you want to overload the = operator on an enum anyway?

because...

Code:

---

if ( (ts>3 ) || (ts<0) ) {
        ts=0 ;
}

// : error C2440: '=' : cannot convert from 'int' to TankStatus'

---

again, ts is enum.... // enum TankStatus {unknown, empty, half, full};

The point of an enum is to provide names for its possible values. You should use those names when assigning it a value, otherwise there's no point in using an enum.

Code:

---

enum TankStatus
{
  unknown,
  empty,
  full
}:

TanksStatus ts;

ts = unknown;

hey you right, thanx :)

elements of an enum can only be assigned values at the point of declaration.

If you define a variable that happens to be an enum (and it is not a const) you can assign to it as much as you want.

Code:

---

enum colors
{
  RED,
  BLUE,
  GREEN
}

colors textColor (RED);

// later I can do this
textColor = BLUE;

Am I misunderstanding your point?
