Help!!!! using switch

Question

Hello I'm using the switch statement and I have a problem.
int x=10;
switch(data) {
     case 2:
break;
case 3:
break;
case x:
break;
default:
break;
When i compile I'll recive this error
"constant expression required" on case x;
How can I solve this problem,
Thank a lot.

Answer 1

switch(data) {
    case 2:
        break;
    case 3:
        break;
/*case x: -- you can not use a variable as a case label.
break; */
    default:
        if (data == x) {
        } else {
        break;
}
