identifiers

A name for a variable, type, type member, template, class, function, namespace, etc.

declared

All variables must be...

e.

Counter controlled repetition requires all of the following except... a. the name of a control variable b. the initial value of the control variable c. the conditional that tests for the final value of the control variable d. the increment/decrement by which the control variable is modified each time through the loop e. all of the above are correct f. all of the above are incorrect

False

Keywords can be used as identifiers for variable names. True or False?

BASIC, COBOL, Pascal, Java, C, ForTran

letters, digits, and underscores

What are identifiers limited to?

repetition, selection, sequence

What are the 3 control structures?

Preliminary, process, output

What are the 3 parts to the first refinement?

initialization, processing, termination

What are the 3 phases of a program?

if, if-else, switch

What are the 3 types of selection structures?

\n (new line), \t (new tab)

What are the escape sequences?

They are all translator languages

What doe compilers, assemblers, and editors all have in common?

invokes object function

What does -.operator do?

Assigns an initial value

What does initializing do?

true and false

What does the data type "bool" represent?

space is allocated in RAM

What happens when an object is created?

conditional operator (?:)

What is C++'s only ternary operator?

dividing by 0

What is a fatal logic error?

counter-controlled loop

What is another term for "for loop"?

do while loop

What is considered a post test structure?

while loop

What is considered a pretest structure?

Concatenate

What is it called when you join 2 strings together?

while loop

What is repetition?

if-else statement

What is selection?

default (ex. cout, cin)

What is sequence?

Accumulators

_______________ need to be initialized

+=

addition assignment operator

Indiscriminate branching

affects the flow of control of coding, using GOTO statements that make code difficult to follow and prone to errors

pseudocode

an artificial and informal language that helps programmers develop algorithms. (similar to everyday english)

class

an expanded concept of a data structure: instead of holding only data, it can hold both data and functions

+, -, *, /, %

binary operators

--

decrement operator

postincrement or postdecrement operator

if an increment or decrement operator is placed after a variable, it is referred to as the...

false

int can represent real numbers. True or false?

scope

This defines where a variable can be used in the program

top

This is a single statement that conveys the overall function of the program

Implementation

This is the coding phase

Design phase

This is the phase where you solve the problem

Analyze Phase

This is the testing phase

do-while loop

This makes sure the code will run at least one time

if

This selection structure either performs an action if the condition is true or skips the action if the condition is false

if-else

This selection structure performs an action if a condition is true and performs a different function if the condition is false

switch

This selection structure performs one of many different actions depending on the value of an expression

ternary operator

This takes 3 conditional operands. The first operand is a condition, the second operand is the value for the entire conditional, expression if the condition is true, and the third operand is the value for the entire conditional expression if the condition is false

control structures

serves to specify what has to be done by a program, when and under which circumstances

Bohm and Jacopini

showed that all programming code could be done through 3 structured programming things - sequence, selection, and repetition

spaghetti code

snarled, unstructured program logic

yes

Is it possible to have more than one object in one class?

data type

Declaring variables specifies what?

truncated

Dividing two integers results in integer division in which any fractional part of the calculation is lost

true

Float handles numbers with decimal points. True or false?

preincrement or predecrement operator

If an increment or decrement operator is placed before a variable, it is referred to as the...

++

Increment operator

True

the C++ compiler ignores whitespace characters. True or False?
