Exercise 1: Create an array @x such that changing $x[0] also sets $x[1] to the same value

Exercise 2: Given a pre-declared function "foo", write a code snippet that invokes it in an infinite loop; in 10 chars

Exercise 4: Dump core in 6 chars

Exercise 5: Create a static variable lexically scoped to a sub, and no wider than that. It's ok if it blows up under recursion
sub foo{my $static if 0}

Exercise 6: Create $x, $y such that $x eq $y && $$x ne $$y

Exercise 8: Create $foo such that ($foo^=0)++ eq $foo++

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
