Cs 110 C++

Front 1

Loop

Back 1

A structure that repeats while some condition continues to be true.

Front 2

Types of loops

Back 2

While (pre-test)

Front 3

While loop

Back 3

pre-test loop. Always based on a boolean expression

Front 4

Types of while loops

Back 4

Sentinel

Front 5

Sentinel-controlled While loop

Back 5

continues until a certain value (variable or constant) is met.

Front 6

Count-controlled While loop

Back 6

uses a numeric variable to count the repetitions until the boolean expression is met.

Front 7

Flag-controlled loop

Back 7

uses a boolean variable as the loop control variable.

Front 8

Do-until loop

Back 8

test is done after the main loop structure executes

Front 9

For loop

Back 9

automatically initializes the loop control variable

Front 10

Nesting loops

Back 10

loops may be put within other loops.

Front 11

File

Back 11

A type of data made of records (usually text) which can be read by a program.

Front 12

Give 5 examples of input devices?

Back 12

1. Mouse 2. key board 3. microphone 4. touch screen 5. scanner

Front 13

Define the term output device?

Back 13

Output is a device that is used to see all the data you inputted into the computer.

Front 14

Give 5 examples of output device

Back 14

1. speakers 2. printer 3. headphones 4. projector 5. monitor

Front 15

Define the term processing device?

Back 15

A processing device is a type of hardware that tranfers the inpuuted data to an output device.

Front 16

Define the term input device?

Back 16

Input is a device where a piece of hardware that is used to put data into the computer system.

Front 17

When you declare an object...

Back 17

...the name is a memory address, or reference.

Front 18

Name the three control structures

Back 18

Sequence

Front 19

In a sequence structure...

Back 19

...you perform a sequence of events

Front 20

In a selection (decision) structure...

Back 20

...you ask a question

Front 21

How many types of selection structures are there?

Back 21

Single alternative/unary (if-then)

Front 22

Repetition structure

Back 22

Also known as an Iteration or Loop structure. In this structure

Front 23

While loop/while-do loop

Back 23

In these loops

Front 24

Stacking

Back 24

attaching structures end to end.

Front 25

Nesting

Back 25

putting a structure within another.

Front 26

do-until loop

Back 26

makes sure a procedure executes at least once

Front 27

Priming read/priming input

Back 27

beginning statement in a structure.

Front 28

Block

Back 28

a group of statements that execute as a whole.

Front 29

Boolean expressions/logic

Back 29

only has two states: true or false. Boolean expressions work in the selection structure.

Front 30

Boolean operators

Back 30

are NOT,AND,OR. Boolean operators follow an order of operations that is as follows, NOT,AND,OR.
These operators create what are know as Compound conditions.

Front 31

NOT operator

Back 31

Reverses the meaning of a boolean expression. NOT is evaluated first.

Front 32

AND operator

Back 32

combines decisions so that both/all must be true for an action to occur.

Front 33

AND is evaluated second (or first

Back 33

if there is no NOT operator).

Front 34

OR operator

Back 34

combines decisions so that only one must be true for an action to occur. OR is evaluated last.

Front 35

Boolean orders of operations

Back 35

Parenthesis/brackets

Front 36

Relational comparison operators

Back 36

symbols that express boolean operations such as =,<,>,<=,>=

Front 37

Case structure

Back 37

A convenient alternative to other structures. Allows one selection between multiple alternatives by testing a variable between several values. Replaces if-then-else structure.

Front 38

what is the smallest number that can be represented in 8 bits?

Back 38

- 128
