The difference between an algorithm and a flowchart.

An algorithm is a list, and a flowchart contains shapes.

What is the final value of X in this algorithm?

X=10

X=X+3

X=X+2

X=X/5

3

300

What is the phrase that goes with this algorithm?

X=20

Y=45

X=X+25

Y=Y-10

If X=Y then phrase = EQUAL, else phrase is NOT EQUAL.

NOT EQUAL

400

What is the final value of Y?

Y=50

Y=Y-45

Y=Y*10

Y=Y+100

Y=Y*2

Y=Y-150

150

What is the final value of H?

H=2

H=H*10

H=H/4

H=H*20

Trace Tables

100

What do trace tables track?

Variables

200

Draw a trace table to find the final value of X.

X=2

Y=4

X=X*5

Y=Y+6

X=X-Y

X=X+21

Y=X

21

Write a trace table to solve for W.

W=45

E=15

W=W-E

W=W*2

E=E+85

60

400

Write a trace table to solve for the phrase.

I=10

K=30

K=K-I

I=I+K

I=I*2

If I>K then phrase is GREATER, else phrase is LESS THAN

Phrase is GREATER

500

Write a trace table to find the phrase.

T=8

R=10

T=T+2

R=R*2

T=T+10

R=R/2

T=T*2

If R>T phrase is GREATER THAN, else phrase is LESS THAN

LESS THAN

Event Handler Charts

100

Event and Description

200

The first app your drew an event handler chart was called...?

Build-A-Body

300

What information do you put in the description of an event?

You write out what should happen when the event occurs.

400

An app has the design requirements of playing music when a button is pushed, and resetting the player when the device is shaken. What are the events in those requirements?

A button is pushed, and a device is shaken.

500

What are the events in the following design requirements?

A start button is pushed and it begins a clock.

The clock counts down from 30 and ends at 0, if the clock reaches zero the user gets a point.

A next screen button is pushed and opens a different screen.

Start button pushed, clock counts down from 30, next screen button is pushed.
