    Unhappy What's wrong with my switch case?

    Please be easy on me, I'm still a new programmer.

    Code:
    using namespace std;
    void Trailer();
    void Cookies();
    void TurtlePower();
    int main()
    {
      int x;
       switch (x){
    
       case 1:
       cout<<"Trailer"; // This is where I want it to display the word Trailer...
       break;
    
       case 2:
       cout<<"Cookes"; // This is where I want it to display the word cookies....
      break;
    
       case 3:
     cout<<"Turtle Power"; // This is where I want it to display the words Turtle Power...
       break;
    
       }
       cin.get();
    }
    //The idea is that the program displays the words after cout whenever the case is selected. I hope you understand this, i'm not very good at posting tags.

    You never say what x is, which could be dangerous. Have something like int x = 2;.

    also, add a default case to catch any other values than the ones you specify.

    Code:
    using namespace std;
    void Trailer();
    void Cookies();
    void TurtlePower();
    int main()
    {
      int x;
      switch (x)
      {
       case 1:
         cout<<"Trailer"; // This is where I want it to display the word Trailer...
         break;
    
       case 2:
         cout<<"Cookes"; // This is where I want it to display the word cookies....
         break;
    
       case 3:
         cout<<"Turtle Power"; // This is where I want it to display the words Turtle Power...
         break;
    
       default:
         cout << "an invalid value was encountered" << endl;
         return 0;
      }
      cin.get();
    }
    I always have a default case in my switches, unless the variable being switched is of an enum type. then the compiler checks to see what the value is, and throws warnings or errors if it is outside the valid range for the enum.
