Variables can be declared in a switch statement. You'll just need to declare them and use them within a new scope in the switch statement. For example,
#include<iostream>
using namespace std;
int main() {
int i = 10;
switch(i) {
case 2:
//some code
break;
case 10:{
int x = 13;
cout << x;
}
}
return 0;
}This will give the output:
13
If you try to declare the variable out in the open you might get an error as Jumping to a case label is the same as using goto, so you aren't allowed to jump over a local variable declaration while you're in the same scope as it and might be using it someplace further in that scope.
