    first, use [code] tags
    ╔╗╔══╦╗
    ║║║╔╗║║
    ║╚╣╚╝║╚╗
    ╚═╩══╩═╝

    Try creating the array for the password on the heap.
    example:
    Code:
    int size = 0;
    char *password = NULL;
    
    cout << "Enter a size: ";
    cin >> size;
    
    password = new char[size];
    
    if(letters == NULL)
    {
      cout << "allocation failed !" << endl;
      return 1;
    }
    
    // free up memory when done
    delete [] password;
    password = NULL;
