國立暨南國際大學 103 學年度第二學期小考試卷

1. (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).
   
   // HW03 - Space Deleting
   #include <iostream>
   using std::cin;
   using std::cout;
   using std::endl;
   int main()
   {
       int len;
       char s[] = "This is a book.";
       const int MAX_LEN = sizeof(s);
       for(len = 0; s[len] != '\0'; len++)
       {
           while(s[len]==' ')
           {
               cout<<s[len];
               len++;
               while(s[len]==' ')
                   len++;
           }
           cout << s[len];
       }
       cout<<endl;
       return 0;
   }
   
   
   
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).
   
   // Two-dimensional Array
   #include <iostream>
   using std::cout;
   using std::endl;
   
   int main()
   {
       char name[5][20] = { "Alice", "Bob", "Charlie", "Dennis", "Emma" };
       cout << sizeof(name[4]) << endl;
       cout << sizeof(name[4][4]) << endl;
       return 0;
   }
   
   
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).
   
   // Pointer vs. Array
   #include <iostream>
   using std::cout;
   using std::endl;
   
   int main()
   {
       const char* name[5] = { "Alice", "Bob", "Charlie", "Dennis", "Emma" };
       cout << *(name + 2) << endl;
       return 0;
   }
