Intro to Programming - CS3

Question 1

What are the arithmetic operators?

Answer 1

+, -, *, /

Question 2

What are the relational operators and what is their result?

Answer 2

, <=, >=, =, <>

Results in True or False

Question 3

What are the logical operators and what is their result?

Answer 3

AND, OR, NOT

Results in True or False

Question 4

What is operator precedence?

Answer 4

First arithmetic, then relational, then logical

Question 5

A=True, B=False
What is A OR B?
What is A AND B?

Answer 5

True

False

Question 6

Expression

Answer 6

Any legal combo that represents a value (could be one or more constants, variables, operators, and/or functions)

Question 7

Arithmetic expression

Answer 7

An expression with numbers, variables, and/or arithmetic operators

Question 8

Relational expression

Answer 8

Two arithmetic expressions with a relational operator

Result is TRUE or FALSE

Question 9

Logical expression

Answer 9

Has logical operator (and, or, not)
AND/OR need TWO operands
NOT needs only one

Question 10

Structured Programming

Answer 10

Breaking a program into logical sections, using only three types of control structures

Question 11

Control Structures in Structured Programming

Answer 11

Sequence
Selection
Iteration

Question 12

Sequence control structure

Answer 12

One statement simply follows another in sequence; steps are executed in order.

Question 13

Selection control structure

Answer 13

Program selects a path based on conditional statement
IF-THEN or
IF-THEN-ELSE

Question 14

Iteration control structure

Answer 14

Looping or repeating control structure - statements execute repeatedly 
While Loop (WHILE condition is true, execute) 
For Loop (counter-controlled loop, execute specific number of times)

Question 15

What is a keyword?

Answer 15

A word that has a special meaning to the compiler

Question 16

What are each of these words?
Dim score as string
score = Textbox1.Text

Answer 16

Dim _ as > keywords to declare variable
score > name of variable 
string > data type 
= > assignment
you are assigning the TEXT property of the Textbox1 CONTROL to the variable score

Question 17

And

Answer 17

Both operands must be true for the expression to be true, otherwise it is false

Question 18

Or

Answer 18

One or both operands must be true for the expression to be true, otherwise it is false

Question 19

Not

Answer 19

Reverses the logical value of the expression

Question 20

Variable naming rules

Answer 20

1. Can only have letters, digits, and underscores
2. Cannot start with a number
3. Cannot use a keyword

Question 21

Literal data

Answer 21

Any data in a program that explicitly identifies itself

Question 22

Symbolic constant

Answer 22

Defining a constant

Const float Pi = 3.14
