declaring variables in switch statement

[Mike P]

Is it not possible to declare variables within a switch statement? My
variables don't seem to ever be in scope to be able to assign values to
them.


Thanks,

Mike

Could you provide an example showing your problem? It'll help someone answer
you(I won't be here long enough, unfortunatly).

Hi Mike,

You can declare variables inside a switch statement, but it will go out of scope as the statement goes out of scope.
If you want to use the variables after the switch you need to declare them before the switch, with a default value.

int j = -1;

switch(myValue)
{
case 0:
j = 200;
break;
}

int k = j*3;
