1. (10%) Determine whether the syntax of the following code is correct or not.  If it is correct, predict its output.  If it is incorrect, point out the mistake(s).
   // *(a + i) == a[i]
   #include <iostream>
   using std::cout;
   
   int main()
   {
       int a[] = { 1, 2, 3, 4, 5 };
       int b[] = { 6, 7, 8, 9, 10 };
       for (int i=0; i<5; ++i)
       {
           * (a + i) *= * (b + i);
           cout << a[i];
       }
       return 0;
   }
   
   
   
2. (10%) Determine whether the syntax of the following code is correct or not.  If it is correct, predict its output.  If it is incorrect, point out the mistake(s).
   #include <iostream>
   using std::cout;
   
   void stars(n);  // function prototype
   
   int main()
   {
       stars(5);
       stars(5);
       return 0;
   }
   
   void stars(int n)
   {
       int i;
       for (i=0; i<n; ++i)
           cout << '*';
       return;
   }
   
   
3. (10%) Determine whether the syntax of the following code is correct or not.  If it is correct, predict its output.  If it is incorrect, point out the mistake(s).
   // pass by reference
   #include <iostream>
   using std::cout;
   using std::endl;
   
   void stars(int& n)
   {
       for ( ; 0<--n; ) cout << '*';
   }
   
   int main()
   {
       int n = 6;
       stars(n);
       cout << n << endl;
       return 0;
   }
