Multiple variables

Would this be ok?

Code:

---

if ( a, b, c, d == 1  || a, b, c, d == 2 || a, b, c, d == 3 || a, b, c, d == 4 || a, b, c, d == 5 ) {

---

Or is this wrong with int a, b, c, d;

It's valid C, but it won't do what you expect. You would need to test each individual case...

Code:

---

if ( (a == 1 && b == 1 && c == 1 && d ==1) || (a == 2 && b == 2 && c == 2 && d == 2) ...

---

The comma operator cannot be used in the way you describe.

Thanks :D
