Flow Charts

Front 1

Flowcharting Standard Process:

Back 1

Input Data, process/computation, output

Front 2

3 kinds of flow charts

Back 2

Sequential

Selection/decision

loop,repetition, iteration

Front 3

Flowcharting Guidelines

Review Pg. 105 of Packet

Back 3

yes do it now!

Front 4

Decision Diamonds are tests of equality and either return true or false?

Back 4

true!

Front 5

you should generally use long variable names when flowcharting.

Back 5

false!

short-it allows you to keep them compact and easy to draw

Front 6

variable names SHOULD NOT be separated by spaces

Back 6

true

Front 7

flowcharts should always include a legend to show sort variable and their associated meanings

Back 7

true

Front 8

Programs usually consist of 5 fundamental "flow control patterns"

Back 8

false!! 3

Sequence

Selection/Decision

Iterating/Repetition/(loop)

Front 9

flow control patterns regardless of which they are, always have 1 input and 1 output

Back 9

true

Front 10

the various flow control patterns cannot be combined to solve a prolbem or create a program

Back 10

false! ANY program can be written using 1 or all of these combined in some way

Front 11

goto

Back 11

obsolete programming control feature that allowed programmers to jump all over their flowchart--made it very confusing and difficult to maintain and update programs . goto is a bad practice because it removes the linear movement through a program

Front 12

conceptually every If-Then statement has __ parts. What are they?

Back 12

4

diamond (logical Test)

true branch (do-if-true)

false branch (do-if-false)

end (represented by the connection circle)

Every diamond has 1 corresponding connection circle

Front 13

the ____ loop is the most common type of repetition structure

Back 13

while loop

Front 14

inputs can come from ___ sources.

Back 14

2--distinguised on the flowchart by "input" (from user) and "Input from setupe" (previously stored from computer)

Users

or from data stored in a setup section (computer)

Front 15

what are the 2 kinds of inputs?

Back 15

Initial

Control--Input entered ATER algorithim has began

Front 16

to get loop termination condition correct, it can be helpful to track teh changing values of variables within the algo with one or more test cases

Back 16

true--called a loop termination table

Front 17

Review Narratives & corresponding Flow Charts--Pay attention/memorize the symbols for each part of the flowchart

Back 17

<b>yes do it now!

Where does flowcharting fit in to system dev?

Back 18

Front 20

Algorithm is

Back 20

the Logic & Calculations and how and when things are supposed to happen to produce the desired output using the input

Front 21

Do the Practice Flowcharting Problems from Blackboard

Back 21

<b>yes do it now!

Front 22

Inputs can sometimes be includes with outputs?

Back 22

true!

outputs need a logical association with something the user can understand. inputs placed with outputs have () placed around them to distinguish them

Front 23

3 types of output exist for flowcharts

Back 23

Display

Print

Prompt

Front 24

although variables can be included in input/output symbols, in ordert o keep the flowchart simple and compact, field labels are NOT included. These are added after flowcharting, when the algo in the flowchart is dev. into a physical system.

Back 24

true
