Exam 2 Grading...

Paper part, 20 points.
1 and 2 - 12 points total.
* 8 points for whichever problem you did better on, 4 points for the other.
  Most people did better on problem 1.
* 1/2 of the points for the correct final result, 1/2 for showing
  variables and functions.
* Number 1 - -1 if everything correct but showed it for i=i+1 instead of
             i=i+5

Number 3.
* -1 if listed 4 parts correctly with no explanation
* -2 example given for 4 parts, but they are not named or explained.
* -1 if skipped one of the 4 parts.

Notes:
* if, while, for - they can all optionally not use {} if there is a single
  statement that is the body of the loop/if-test.
* there does not have to be an if before a while loop.
* keeping track of which function a variable is in matters...


Computer part, 20 points.

exam2a is 6 points total - 3 points for 1 error fixed, 1.5 points for each 
additional.
- For second fixed error, if the code compiles but still doesn't work 
  right because it didn't really fix it correctly, 1 point instead of 1.5.

exam2b.c, exam2c.c, exam2d.c, exam2e.c are all "create your own program"       questions, where each one builds on what you did in the last one.             
They are worth 14 points total, and the grading is something like             
none correct, but some sort of totaling happening in exam2b and some sort
of printf/scanf happening in exam2c - though niether is correct, and both
show issues: 4 points.
exam2b correct, none others: 7 points                                         
exam2b, exam2c correct: 11 points                                             
exam2b, exam2c, exam2d correct: 13 points                                     
all correct: 14 points     

In other words, best one is worth 7 points, 2nd is 4 points, 3rd is 
2 points, last one is 1 point.

exam2c.c
* 5/7 If the best part and doing printf/scanf right, but after the loop rather
  than before as it should be.
