hi
how would i write the following in switch case statement:
if (x < 40)
y = 0;
else if (x < 65)
y = 1;
else if (x < 80)
y = 2;
else if (x < 90)
y = 3;
else if (x < 96)
y = 4;
else
y = 5;
is it easy or not possible?
thanks

It's not possible, I'm afraid. Case statements use equality.

Not possible.

Hmmm.
I couldn't figure out a C# version.
But for kicks, I tried to write a VB.net version, and it worked.
Private Sub SelectCaseTest( )
Dim x As Int32 = 11
Dim y As Int32 = 0
Select Case x
Case Is < 10
y = 11
Case Is < 20
y = 21
Case Else
y = 999
End Select
Console.WriteLi ne(String.Forma t("{0}, {1}", x, y))
End Sub
Hmmmmmmmmmmmm.
This was all I could come up with, but I didn't try too long: But its not a
solution I know.
private static void SelectCaseTest( )
{
int x = 11;
int y = 0;
switch (x)
{
case 1:
case 2:
case 3:
case 4:
case 5:
case 6:
case 7:
case 8:
case 9:
case 10:
y = 11;
break;
default:
y=999;
break;
}
Console.WriteLi ne(string.Forma t("{0}, {1}", x, y));
}

I don't think it's possible because the case statement doesn't accept
operators, only absolute values...
But for kicks, I tried to write a VB.net version, and it worked.
Another one to add to the list of differences :-)
case 1:
case 2:
case 3:
case 4:
case 5:
case 6:
case 7:
case 8:
case 9:
case 10:
y = 11;
Not much good if x <= 0 :-)

Hi Graeme,
Unfortunately, switch statements only work across constant values so there's
no easy way to represent those statements. However, if you think about it,
it's more concise using the if..else if statements you have already, since
a case statement *must* include a 'break;', meaning you will be adding an
extra line of code to each condition.

Hope this helps,
Tom Spink
Google first, ask later.

[snipped]
For what it's worth (in addition to the good comments you've received
already), it seems to me that what you're doing would be easily (and maybe
more elegantly) handled using an array to define the mapping. For example:
int [] mpivalinum = new int[] {40, 65, 80, 90, 96};
int y;
for (y = 0; y < mpivalinum.Leng th; y++)
{
if (x < mpivalinum[y])
{
break;
}
}
It has more lines of code for a few numbers, but about the same for the
handful in your example, and a lot less as the number of cases goes up.

setting the variables 'z' or 'y' to differing numbers, the following

does not. (the code's function is illustrative.)

I've been delving into finite state machines and at this time it seems that
the best way to implement them is through an intense use of the goto
statement. Yet, everyone plus their granmother is constantly cursing at the
goto statement, accusing it of being some sort of spawn of satan. So it
seems we have a pickle here.
The thing is, at first thought it seems that there aren't any viable
alternatives which are better suited for this...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
