General Comments

• Problem 3: A typedef does not allocate any memory.
• Problem 4: Most common mistake, confusing . and ->
• Problem 5:
  • Remember to skip the name of the program.
  • You lost 5 points if you did not correctly address the first character of each command line argument.
• Problem 6:
  • Make sure you check for EOF before outputting any character
  • Make sure you output the newline.
  • Only blanks (' ') are removed, not tabs.
  • " " is not a character, it is a string.
  • If your main loop is
    while ( (c=getcahr()) != '\n' )
    then your program will only process one line.
  • Characters can be processed one at a time. You do not have to assume a maximum line length.
  • The input is not a string. Do not check for the string terminator.
• Problem 7:
  • You may not use strcmp, unless you write it.
  • You should write a string compare function rather than trying to do the comparison in-line.
  • If you use:
    while(start -> next != NULL)
    you will probably not check the last entry.
  • Make sure you understand the difference between . and ->
