    Menu Loop

    Hello. I am trying to do a try.. catch statement and where there is exception error thrown, i want it to go back to the beginning. I have done the following, but I know I have made a mistake somewhere, but am stumped. Please assist me here

    here is the code :

    Code:
    #include <iostream>
    using namespace std;
    
    void printList(short list[]);
    
    int main()
    {
       short n[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
       int index=0, value;
    
       printList(n);
    
       while (index != -1)
       {
             try
             {
              cout << "Enter array index (0..9) to update (-1 to quit): ";
              cin >> index; 
              
              if (index > 10)
                 throw 1;
                     
              
              else if (index == -1)
                 break;
              }
              
              catch (int index)
              {
                    cout << "Exception thrown" << endl;
              }
              
              cout << "Enter new value:  ";
              cin >> value;
    
              n[index] = value;
              printList(n);
              
       }
       return 0;
    }  
    
    void printList(short list[])
    {
       cout << "List: ";
       for (int i=0; i<10; i++)
           cout << list[i] << " ";
       cout << endl; 
    }
    thank you all !

    Code:
              catch (int index)
              {
                    cout << "Exception thrown" << endl;
                    continue;
              }
    All questions are easy. The answers cause the problem...
