Quality of code and tests:
1) Good coding practices
* H - Main header for the program is missing
* FH - Function headers are missing
* struct - Program lacks structure. For example, long program, all written
under the main function. Could have been split into smaller, meaningful
fuctions
* C or Comments: Useful comments missing. Instead of function headers
could have atleast have comments.
* MN - Magic numbers. mostly for wordsize. Encountered exit(1) or exit(99)
or return(0) return(1), where it should have been exit(SUCCESS) or
return(TRUE) ETC.
*Const - did not define constants for comment symbols such as '//' or '*/'
etc.
* vars - could have used more meaningful variable names

2) Testing
Not enough to just test on A1 and A2.
Mostly encountered several untested cases such as:
* wrong number of input arguments
* missing file (wrong file name or wrong directory)
* blank file
Most assignments were well tested for different cases of comment lines.
