1. (10%) Determine whether the following code has syntax errors or not.  If it is correct, predict its output.  If it is incorrect, point out the mistake(s).
   // array of pointer
   #include <iostream>
   using std::cin;
   using std::cout;
   using std::endl;
   
   int main()
   {
       char* greek[] = { "Alpha", "Beta", "Gamma", "Delta", "Epsilon" };
       // cout << greek << endl;    // This will print the starting address of the array
       cout << *greek << endl;
       cout << *(*greek) << endl;
       return 0;
   }
