of speed, capacity, volatility, and cost Input and outputHow it all works together

Questions?

Anything out of date in this chapter?

What’s the Deal With That Pesky For Loop??

for ( INIT ; TEST ; NEXT) {BODY

}

Your for loop always, always, always must have this form – you can put different things for INIT, TEST, NEXT, and BODY, but the rest has to look just like this!

INIT NEXT

BODYTEST?

yes

no

CMPE

The PointEach of you has declared a major of BTA, IS,

CMSC, or CMPE

You can change your major

It’s better to change your major sooner rather than later

We want to help you make the right choice for you

If we do our jobs, you’ll have a much clearer idea of what major you want, what you can do with it, and why it’s right for you

Project TeamsGet into your new teams and come up with answers to

these questions:

1. Find one thing that you all have in common.

2. Find one thing that’s different for all of you (the answer “we all have different names” does not count!)

3. Pick a team name. (Maybe the answers to #1 and #2 will inspire you.)

NOTE: For this and other team activities, any team member may be asked to present the answer to any question!
