Test Key -- CS1044 Spring 2002, Test #2

FORM A:

1. 5  Trace gives I: 12 11 10  9  8
                  J:  0 11 21 30 38
2. 6
3. 9  while, for, do...while are interation mechanisms
4. 5  Trace gives j: 2 5 8 11 14 17 20 23 26 29...
5. 3  The eight value is 23
6. 7  mystery is 5, the values of sum are 3, 1, 5, 6, 13
7. 8  the values of sum are 5, 8, 6, 10, 11, 18
8. 4  the values of sum 5, 8; -2 terminates the loop
9. 6  sum is incremented 6 times (3 times for each of two i loops)
10. 3  sum is reset to zero after first i loop
11. 9  a reference parameter must be a variable
12. 7  must include "out of the function"
13. 3  alpha is a value parameter, beta a reference parameter
 or 6  the prototype must include the type of the function
14. 4  the call to DoThis changes the value of Ben in main from -5 to 95.  Temp and Jerry retain their original values of 15 and 42.
15. 3
16. 8
17. 5  an integer is return when a character value parameter is passed
18. 3  the for loops writes out two Es
19. 1  N will be increased to 143, but the last N output is 71.
20. 2  the 75 character array has indices 0 through 74.
21. 5  4 values are output from Ray[4] to Ray[1]
22. 8  only 1 and 3 output Fred[0], Fred[2], Fred[4]...
23. 2  syntactically legal, but aRay[5] and bRay[5] are not allocated
24. 1  the order fo the parameters 4 and aRay should be reversed.
25. 3  since bRay[4] is 2, this is both syntactically legal and logically correct.
26. 2  arrays are passed by reference by default, no & is needed
27. 1  HowMany is an integer value parameter
28. 1  only the index needs to be initialized.
29. 2  the last index is HowMany-1
30. 3  the index is changed to Look
