runShortExperimentfunction repeats the short exercises from Mini-Lab 1, and adds several new exercises involving more complicated expressions.
runShortExperimentdo? (This is the only statement that is not commented-out.)
alertstatement. (There will still be a comment to the right of the statement, at the end of the line.) What will the function will do now? Update the comment with what you expect the result to be, then test it.
+operator does when used with numbers, strings, or a combination of both. Again, document your expected results in the comments at the end of line, then test that your expectations were correct.
The final set of statements in this function will allow you to experiment
what happens when addition and multiplication operations are combined in
the same statement. Starting with just the first two statements, think
about what you think the output will be, edit the Expected Results (e.g.,
42, or whatever you think the
output will be), uncomment the statements, and run the experiment.
What about the third statement in the block? Do you expect its behavior to be the same as the first statement or the second statement, or neither? Test it. Then go on and do the same for the final two statements in the function.
Edit the main COMP 105 web page you created in the first lab and add a link to your new Working with Numbers, Part II page. (This should be your third link in your set of links to COMP 105 assignments, after Mini-Lab 1 and MadLibs.)
If you worked in a team, each member of your group should do this, so each of you has a link to the new page.
people.kzoo.eduserver (remember that its host name for uploading is
peopleftp.kzoo.edu). Test that the link to the Mini-Lab Follow-up works on the server by clicking on it from your home page.
