Multiple Choice

What does a programmer do?

• Works with real-time databases in order to manage large quantities of data

• Works with programming language(s) to write code for applications

• Creates static web pages for informational purposes using only Hypertext Markup Language

• Develops file storage systems for enterprise networks

CompTIA ITF+ Programming

A.

Works with programming language(s) to write code for applications

System administrators develop file storage systems for enterprise networks.

Web designers create static web pages for informational purposes using only Hypertext
Markup Language.

Database administrators work with real-time databases in order to manage large quantities
of data.

Computer Programmers work with one or more programming languages to write
code that is used as the basis for the applications you use on your computing
device.

What is a program BEST described as?

Multiple Choice

What is a program BEST described as?

• Proprietary software to which the owner has exclusive rights

• A mathematical equation utilizing compiled code to execute commands

• A sequence of instructions for your computer to perform

•  A piece of software designed for business to streamline commonly used tasks

CompTIA ITF+ Programming

C. A sequence of instructions for your computer to perform

Not all programs contain mathematical equations or use compiled code.
A program may have many uses, both personal and commercial.
Streamlining tasks is only one purpose a program could serve.

While a program could be proprietary, it doesn't have to be. Some software
programs are considered open source and are a compilation of contributing
developers around the world.

A program is a sequence of instructions for your computer to perform
that is designed by a computer.

CompTIA ITF+ Programming: SDLC

The Software Development
Life Cycle is a blueprint
designed for a team to
create, maintain, and fix
digital products.

CompTIA ITF+ Programming: Flow Charts

Flow Charts

A flow chart will visualize the graphical sequence of a
program.

This provides a visual representation of
program flow in the Analysis
or Design phase of the Software
Development Life Cycle.

CompTIA ITF+ Programming: Flow Charts

•Flow Charts

• All programs can be represented by flow charts
• 4 main symbols:

Oval: Start/End

Arrow: Path/Direction

Diamond: Decisions

(yes/no)

Rectangles: Processes

CompTIA ITF+ Programming

Flow Chart design for ordering a pizza

CompTIA ITF+ Programming

Flow charts are often turned
into pseudocode (pronounced
sudo-code) during the Design
phase of the SDLC

CompTIA ITF+ Programming

Pseudocode will provide a more detailed and human-readable form of
the algorithm.

Pseudocode is informal, high-level description of the algorithm

• Not a real programming language
• General idea of concepts

CompTIA ITF+ Programming

Pseducode algorithm for taking a pizza order:

Identify the pizza size selected

Identify the pizza base selected

Identify the topping choice selected

IF additional toppings required THEN

Add to the topping choice

ELSE

Identify if another pizza is to be added

END IF

IF another pizza is to be added THEN

Identify the pizza size, base and topping

ELSE

Calculate order price

Display order

END IF

What will this program do?

Multiple Choice

According to the flow chart and pseudocode, what will this program do?

• This program will ask the user for input.

  The user will type in all 5 numbers, n.

  The program will print the sum of those 5 numbers.

  The program will end

• The program initializes the counters to zero

  The user will input the first number, n

  The program will calculate the sum

  The program will increase the counter to 5

  The program will print the sum of the number

  The program will end

• The program initializes the counters to zero

  The user will input the first number, n

  The program will calculate the sum

  The counter will increase by 1

  The user will input the second number, n

  The counter will increase by 1 until the count get to 5

  The program will print the sum of the number

  The program will end

• The program initializes the counters to zero

  The user will input the first number, n

  The program will calculate the sum

  The counter will increase by 1

  The user will input the second number, n

  The counter will increase by 1 until the count is greater than 5

  The program will print the sum of the number

  The program will end

Multiple Choice

According to this flowchart and the pseudocode, what purpose does the count variable serve in this algorithm?

• The count variable will increase by 5 until the condition count < 5 is true

• The count variable will increase by 5 until the condition count < 5 is false

• The count variable will increase by 1 until the condition count < 5 is false

• The count variable will increase by 1 until the condition count < 5 is true
