2. Which method produces the fastest program?
1. Write in machine language or assembly?
2. Write in C++
3. Write in Java
4. Write in Perl

4. What is "3 4 + 1 5 * +"? ________________________
5. What is "+ 3 * 2 1 + 4" _________________________
6. (Three points)  Write me a grammer that matches all pathnames in a filesystem.  It should match "/",  "/heart" "/heart/love/mooshy" but NOT "/cuddle/" and not "/love//hurts"
   
   
   
   
   
   
   
   
   
   
   
7. (Two points) Here is a grammer.  Parse the two inputs based on this grammer.
   test := expression "==" expression                         Input #1:      3 + 4 = 2 * 5 + 3
   expression := factor * term | factor                         Input #2:      2  = 3 * 5 * 2 
   factor := term + term | term
   term := "(" expression ")" | number
   
   
   
   
   
   
   
8. In the grammer above, which has higher precedence, "+" or "*"? ___________________
9. I'm a compiler.  I want to implement a case statement.  My case statement has choices 1,2,3,4,5,6,99999999999.  Which method should I use?
1. Jump table
2. Bunch of if's (conditionals)
3. Hash table
10. What does this program in C++ print?
    main() {
        for(int i = 0; i < 3; i++)  {
                  continue;
                  cout << "Bunny foo-foo!\n";
         }
    }
11. Does this program fragment generate a divide-by-zero error?
    int a = 0;
    if (10 / a == 3 && a != 0) cout << "Sweatheart\n";
12. There are two ways to store a string.  Char's followed by  zero or length followed by chars.  Give one string operation (besides count-the-length) that is faster with the second type than the first.
    _____________________________________________________________________________________
13. I have a Java array declared as 'int boyfriendmap[10][20][30].  The array starts at location 10,000.  Where is a[3][2][4]? _____________________________
14. What does this code print using call-by-value? _____________  Call by reference? ____________________
    int g1 = 1;
    main() {
         int g2 = 2;
         cout << sweetums(g1, g2):
    }
    int sweetums(int a) {
         a = a * 3;
         return a + g1;
    }
15. Which of these things appears in an activation record on the stack during a procedure call?  Choose all that apply.
1. Local variables to the procedure being called
2. Global variables to the program
3. The program counter where the caller was when he called.

         int location;
         void print() { System.out.println("Smoch!"); }
    }
17. Given the classes below, does Squeeze have a field 'location'?  ____________ What line would assign 12 to 'length' of an instance name 'fred' of Squeeze ____________
    
    

class Squeeze extends Hug {      public boolean mixbreathes; }

Class Hug extends Touch {      protected int length; }

Class Touch {      private int location; }

18. Connect the word and the concept.  Everything gets ONE partner
    
    

C++                                            Can be used to implement a 'increment' function Java                                           Interpreted Pass By Reference                              Array bounds checking Pass By Value                                  Virtual Functions Helps Catch Errors                             Used for small data items in C++ Faster                                         Compiled Slower                                         Non-Virtual Functions Love                                           Candy Samples
