   using std::cout;
   using std::endl;
   
   int main()
   {
       double array[] = {1.0, 1.5, 2.0, 2.5, 3.0};
       char *stars[] = { "Catherine Zeta-Jones",
    		      "Angelina Jolie",
   		      "Nicolas Cage",
   		      "Sean Connery",
   		      "Arnold Schwarzenegger"
   		    };
   
       cout << sizeof array << "\t" << sizeof array[0] << endl;
       cout << sizeof stars << "\t" << sizeof stars[0] << endl;
   }
   
       

2. (10%) Determine whether 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;
   using std::endl;
       
    // This function returns a pointer to an integer
       
   int *max(int a, int b)
   { 
   	return (a>b) ? &a : &b;
       
   }
   
   int main()
   {
   	cout << *max(3,5) << endl;
   	cout << *max(10,1) << endl;
   }
   
   
   
   
   

3. (10%) Determine whether 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;
   using std::endl;
   
   void eat(char* str)
   {
   	int i = 0, j = 0;
   	while ((*(str + i) = *(str + j++)) != '\0')
   		if (*(str + i) != ' ')
   			i++;
   	return;
   }
   
   int main(void)
   {
   	char message[] = "TODAY IS WEDNESDAY.";
   	eat(message);
   	cout << message << endl;
   }
