General Comments

• Problem 1:
  • Many people still do not know what a filter is.
  • May only use getchar and putchar here.
  • An empty line cannot contain blanks and tabs.
• Problem 2:
  • sizeof is not the same as strlen.
  • If you change argv[i] you cannot then print out the string.
  • Do not output more than what was asked.
• Problem 3:
  • This program requires a string compare, not just a compare of pointers.
  • Either use the library function or write your own.
  • Do not put the string compare code inside of this function.
  • Make sure you have a space between fields.
  • Make sure you output a newline at the end.
• Problem 4:
  • Watch out for infinite loops when the hash table is full.
  • Be sure to handle the wrapping of the index correctly.
  • Don't treat first comparison as special case.
  • You must use symbolic values for the status values.
