Grading Guidelines for hw5
==============================================================
Problem 1a. 10 points

-5 if they put it all within main, without writing a DotProduct function.
Test on a few cases, such as:


% /html/courses/cse110/hw5p1a
enter an integer n: 4
enter A[0] of vector A: 1 
enter A[1] of vector A: 2
enter A[2] of vector A: 3
enter A[3] of vector A: 4
enter B[0] of vector B: 1
enter B[1] of vector B: 2
enter B[2] of vector B: 3
enter B[3] of vector B: 4
the dot product is 30


==============================================================
Problem 1b. 30 points

The problem didn't say that they had to use their DotProduct function
part a, so it's okay if they didn't.  

-10 if they did it all within main, w/o writing a function MatrixMult.

Test it on a few cases:
% /html/courses/cse110/hw5p1b
enter an integer n: 2
enter A[0][0] of matrix A: 4
enter A[0][1] of matrix A: 3
enter A[1][0] of matrix A: 2
enter A[1][1] of matrix A: 1
enter B[0][0] of matrix B: 4
enter B[0][1] of matrix B: 3
enter B[1][0] of matrix B: 2
enter B[1][1] of matrix B: 1

==============================================================
Problem 2a. 10 points

-5 if they didn't put the '\0' at the end of the array

It's okay if they had the function return the effective length of the
array, although it's not necessary.

==============================================================
Problem 2b. 10 points

-5 if it only works on even length words but not odd length words
-5 if it only works on odd length words but not even length words


it's okay if they added a parameter to reverse to take in the effective
length of the array, although it's not necessary.
==============================================================
Problem 2c. 20 points

It's okay if they added parameter to LexOrder to take the effective lengths
of wordA and wordC, although it wasn't necessary.

-10 if it doesn't handle properly 
the case of words in which one is a prefix of the other:

% /html/courses/cse110/hw5p2c
enter a word: abc
enter a word: abcd
abc comes before abcd
% /html/courses/cse110/hw5p2c
enter a word: abcd
enter a word: abc
abc comes before abcd

test on a few other cases.

==============================================================
Problem 2d. 20 points

full credit if they wrote the function correctly, but it doesn't work
because of erros in their LexOrder or Reverse functions.
