#include<iostream>

using namespace std;

int main()
{
    int num =3;

    switch(num)
    {
    case 0:
        int v = 4;  // this will give an error
        // ...
        break;
    case 1:
        {              
            int q = 5;  //inside a block is OK
            // ....
        }
        break;
    default:
        //...
        break; 
    }
}

i want to use that variable just outside that switch block

Then you would have to declare the variable prior to entering the switch block.
