A

Parallelograms

23
Q

Show the flow of the process, or the sequence in which operations are executed

A

Arrows

24
Q

represent connectors, indicating the flow charts, continuation on another page or junction in flow chart

A

small circles, or elipses

25
Q

Flow charts can make complex processes and algorithms easier to understand the visualization

A

Visual clarity

26
Q

With the help of a flow chart, problem, solving and analysis become more efficient

A

Effective analysis

27
Q

Flowchart serve us a good form of documentation, providing a visual archive of various processes

A

Documentation

28
Q

flowcharts can aid in discussing and conveying ideas to team members or stakeholders

A

Improved communication

29
Q

for very complex, algorithms flow charts can become large and unwieldy

A

Complexity

30
Q

charts are high-level diagrams when it comes to coding, the specifics of a programming language need to be considered which the flow chart might not be captured

A

Language specific

31
Q

If the algorithm changes the flow chart needs to be updated, which can be time-consuming for intricate diagrams

A

Updates

32
Q

This is a name that can be assigned value, and then used to refer to that value throughout your code

A

Variables

33
Q

Variable names cannot begin with a digit true or false

A

True

34
Q

These are lines of text that don’t affect the way your program runs

A

Comments

35
Q

Integers can be binary values and octal values, as well as hexadecimal values, true or false

A

True

36
Q

A floating point consists of a decimal point and can also make use of negative values, true or false

A

True

37
Q

Making use of double quotes to define the string, true or false

A

True

38
Q

null object makes use of the “none” keyword, true or false

A

True

39
Q

The volume operator is applied to are called operands true or false

A

True

40
Q

It allows you to specify or convert a type of variable

A

casting

41
Q

Generic term for an ordered set

A

Sequence

42
Q

A

Lists

43
Q

Like lists, they are immutable they can’t be changed

A

tuples

44
Q

A collection of key value pairs

A

Dictionary

45
Q

These are used to compare two values or variables

A

Relational operators

46
Q

This returns true if both conditions are true

A

and

47
Q

Returns through if at least one of the conditions is true

A

or

48
Q

Return the opposite boolean value

A

not

49
Q

this involves expressions involved in keyword, such as if elif and else

A

Conditionals

50
Q

Represent one of the two values true or false

A

booleans

51
Q

It decides whether certain statements need to be executed or not

A

if

52
Q

Statement is used to check additional conditions if the first condition is evaluated as false

A

elif

53
Q

statement will only execute its body, if only preceding, conditional statements, all evaluate to false, otherwise it will not be executed

A

else

54
Q

These are also used for validation and authentication when the program asks for a user input

A

nested if-else statements
