HW7 grading.

20 points total.

0 points - no hw7.c file in your handin directory.

5 points if hw7.c has something reasonable-ish in it but does not compile.

10 points if it runs and password part is correct (including loop) but no 
   triangles/squares.

10 points if password part is correct with small problem and one 
   triangle/square is printed.

13 points if password part correct and at least one triangle/square printed.

16 points if password correct, ask user for width of triangle/square and it 
   is used correctly to print one triangle/square.

18 points if password correct, ask user for width, and the right number of 
   triangle/squares printed but not in increasing width.


-.5 for small errors:
* including the result of the triangle function in a printf, e.g.
  printf("%c",triangle(5))
  which will print a wierd character.
* using a while loop to do something __ times, but did not initialize 
  the counter variable (so who knows what it will actually be...).
* confusing print statements.  For example, no printf statement asking user
  to enter the number (just a scanf there, so how is user supposed to know
  what to sypte?).
* Using strcmp wrong with the "quit" check makes the program exit early, but
  still works correct if enter password correct on first try.

Extra credit...
2 points if giving choice of printing triangle or square and printing whichever
  correctly.
4 points if doing both triangles and squares, giving the user the choice, and 
  with a really nice user interface (text-based menu system).


Remember...
* Need to check that strmp(password,"cs151") == 0.  Same with "quit".  For
  strcmp, need to check if it is equal to 0 to see if they are the same.
* With scanf, when reading in a number or character, the variable you're
  reading it into needs to have an & in front of it, like
  scanf("%d", &width);
