Homework - Expressions, Loops, Conditions

Reminder: We won't collect homework, we'll just discuss it. You don't even need to write the answers down if you don't want to, or answer all the questions. We just want you to think about these things and do a little research into some of the terminology we are using.

• Consider the following program:

              #!perl

              $frogs = 10;
              $cheese_cake = 0;

              while ($frogs > 0) {
                 $frogs++;
                 print "Glug.\n";
                 print "A frog jumped into the pond.  There are $frogs left.\n";
                 $cheese_cake += 2;
              }

              print "All done.  There are $frogs left.\n";
              print "And by the way, the value of cheese_cake is now: $cheese_cake.\n";
              

• Without running this program on a computer, write down the first 3 or 4 lines of output of this program.
• Will this program run without errors?
• Do you think this program does what the programmer intended it to do?
• Get this program to run on your computer.
• What happens when you run it?
  
• If there is a problem with this program, correct it.
