Why am I getting this message ? What would that be?

Error (active):

Put keys in each "case":

switch (option) {
  case 1:
  {
    int var;
    std::vector<int>v(size);
    std::list<int>l;
    //...
    //...
    break;
  }

  case 2:
  {
    double var;
    std::vector<double>v(size);
    std::list<double>l;
    //...
    //...
    break;
  }

  case 3:
  {
    char var;
    std::vector<char>v(size);
    std::list<char>l;
    //...
    //...
    break;
  }

} // switch
