  32 <p><B>Review Questions:
  33 </B></p><OL><li>What do we mean by the ``equivalence between arrays and pointers''
  34 in C?
  35 <li>If <TT>p</TT> is a pointer, what does <TT>p[i]</TT> mean?
  36 <li>Can you think of a few reasons why an I/O scheme which did not
  37 make you open a file and keep track of a ``file pointer,'' but instead
  38 let you just mention the name of the file as you were reading
  39 or writing it, might not work as well?
  40 <li>If <TT>argc</TT> is 2, what is <TT>argv[1]</TT>?  What if <TT>argc</TT> is 1?
  41 </OL><br>
  42 <br>
  43 <p><B>Exercises:
  44 </B></p><OL><li>Rewrite the <TT>replace</TT> function from last week to remove the restriction
  45 that the replacement substring have the same size.  Be sure to
  46 test it on replacement strings which are larger, smaller, and
  47 the same size.  Should it work if the replacement string is the
  48 empty string?
  49 <li>Rewrite the pattern matching program
  50 (Assignment 6, Exercise 1)
  51 to prompt the user for the name of the file to search in and
  52 a pattern to search for.
  53 <li>Rewrite the pattern matching program
  54 (Assignment 6, Exercise 1)
  55 to accept the pattern and file name from the command line
  56 (like the Unix <TT>grep</TT> or MS-DOS <TT>find</TT> command).
