[Cs3] labs 1 and 2 graded

[Mikhail Nesterenko]

CS3 students,

I graded the labs. The grades are in EVAL directory. General
comments. 

- Make sure your files start with three lines of comments: file
  explanation, your name, modification date
- do not use literal constants for character codes and do not
  rely on the character code table being ASCII
- make sure that your code is at most 80 lines across
- use proper indentation
- use C++ strings and related constructs rather than C-style strings
- use stream input/output rather than C-style functions
- use C++ style casting rather than C-style casting, i.e.
  int(myVar) rather than (int)myVar
  more on casting later in the course.

Thanks,
