   #include <iostream>
   using std::endl;
   using std::cout;
   
   int main()
   {
       char *pstr = "AIRWOLF";
       cout << sizeof( pstr) << endl;
       cout << sizeof(*pstr) << endl;
       return 0;
   }
   
   
2. (10%) What will the following code display?
   // char array
   #include <iostream>
   using std::endl;
   using std::cout;
   
   int main()
   {
       char c[] = "AIRWOLF";
       char* p;
       cout << sizeof(c) << " " << c << endl;
       p = c;
       cout << sizeof(p) << " " << p << endl;
       return 0;
   }
   
   
3. (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).
   // Pointer Arithmetic
   #include <iostream>
   using std::endl;
   using std::cout;
   
   int main()
   {
       short data[5] = { 1, 3, 5 };
       short* pdata = &data[2];
       *(++pdata) = 2;
       *(pdata++) = 4;
       cout << *(pdata-1) + *pdata + *data - data[1] << endl;
       return 0;
   }
