Good morning

I would like to know if is possible to do the following or near?

switch (MenuActual){
case 0, 2, 4, 6, 8:
//do something

case 1, 3, 5, 7, 9:
//do something

}

Thanks on advance
Best regards

No, I think you can only have value.

If this is exactly what you want to do then,

if (menuActual % 2)
{
  // do even stuff
}
else
{
  // do odd stuff
}

Thanks Si

On VB I can have it...

Select Case MenuActual
Case 0, 2, 4, 6, 8
//do something
Case 1, 3, 5, 7, 9
//do something
End Select

Thanks on advance
Best regards

Sadly, thats one nice feature of VB that is not in C.

You'll probably end up using ifs and else ifs.

Try this:

switch (MenuActual)
{
     case 0:
      do1();
      break;
     case 2:
      do1();
      break;
     //... 
           
     case 1:
      do2();
      break;
     case 3:
      do2();
      break;
     //... 
}

Good morning

Groove, please explain me:

switch (MenuActual){
case 0:
case 2:
case 4:
case 6:
case 8:
//do something (action 1)
break;

case 1:
case 3:
case 5:
case 7:
case 9:
//do something (action 2)
break;
}

It will work?

Thanks on advance
Best regards

Yes, it will work.
Any "case" that doesn't have "break" will fall-through to the next case.

Thanks.
I'll try later at night.

Thanks once again

What's up deSilva?

Difficult to say...
Why is C/C++ so primitive?
Why took it so long you got a good answer?
Why couldn't you find out yourself?

Oh, forget it! I'm sometimes in this mood....

What's up deSilva?

I just think s/he's trying to bump her/his post count.

If you think of C (or C++) as a high-level assembly language (which is what C was designed as), you won't ever make the mistake of thinking it "primitive".

15 
if (c & 1) {
   // c is odd
} else {
  // c is even
}

Or perhaps:

if (c >= 0) && (c <=9) {
  if (c % 2) {
    // c is even
  } else {
    // c is odd
  }
}
