Chada Tech is a software engineering company that specializes in custom software design and development for both domestic and international clients. You read more about the company and decide this place would be a great fit for you. You are also happy to find that there is an opening for a junior developer and apply for the position immediately. The skills that you have acquired at SNHU have prepared you for this role. Consequently, you are selected for an interview!
As part of the Chada Tech interview process, you are asked to complete a coding skills test to “audition” for the role. This is a typical interviewing strategy that you may encounter in the field. Companies utilize this technique to ensure candidates can in fact do what they claim they can do. Therefore, this exercise will be based on a problem similar to what you will face in the junior developer role, and you will need to come up with a solution. This is your chance to really show them what you can do!
The Chada Tech interviewing team has provided you with the following problem statement and a document containing a set of functional requirements:
Chada Tech has domestic and international clients. To meet international standard ISO 8601, Chada Tech wants their clients to be able to view a 12- and a 24-hour clock on their website rather than just the standard 12-hour clock.
To stand out as a top candidate, you will need to apply program logic by creating two clocks that display simultaneously and allow for user input using secure and efficient C++ code.
Directions
Develop an object-oriented programming (OOP) application to create two clocks that display simultaneously and allow for user input using secure and efficient C++ code.
1. Review the Chada Tech Clocks Functional Requirements, located in the Supporting Materials section.
2. Review the following flowchart, as it is a graphical representation of the logic you will use in relation to your application’s sequence of functions. A text version of this flowchart is available: Project One Flowchart Text Version.
3. Your code should be properly modularized and written in functions so that your main() has the least amount of code.
4. Before you begin coding, remember that you must demonstrate industry standard best practices in all your code to ensure clarity, consistency, and efficiency. This includes:
a. Inserting in-line comments to denote your changes and to
iefly describe the functionality of the code
. Using appropriate variable, parameter, and other naming conventions throughout your code
5. When your solution is finished, zip your project including all components (CPP, H, and any other files used).
6. Upload your zipped project file to the project submission area.
What to Submit
To complete this project, you must submit the following:
Clocks Code
Submit your zipped project files. Be sure to include a file header with your name.
Pseudocode
Prompt
Your objective is to plan the program flow and logic for an electric coffee maker with the following features:
1. A clock displaying the cu
ent time. To set the time, simply press the ON button twice, then read the hour and minute from the user. When ON is pressed one more time, the time is set.
2. A pre-set time (hh-mm) to start
ewing the coffee
3. Three buttons labelled OFF, ON, and PROGRAM:
a. When the OFF button is pressed, the machine does nothing other than display the cu
ent time.
. When the ON button is pressed, the machine starts
ewing coffee.
c. When the PROGRAM button is pressed, the machine waits for the pre-set time to begin
ewing.
4. An automatic sensor that detects whether all the water has been used. Once the water runs out,
ewing stops.
5. A heating sensor that keeps the coffee at a fixed temperature as long as the button is set to ON or PROGRAM
The machine’s operation can be described as follows. First, the user adds coffee and water to the machine. If the user presses the ON button, the system begins boiling the water and then mixing it with coffee. The mix goes through the filter into the glass container. If the OFF button is pressed, the machine shuts down and the cu
ent time is displayed. If the PROGRAM button is pressed, the machine goes into sleep mode until the preset time is reached. Once it’s reached, the machine “wakes up” and makes coffee.
Directions
Remember that pseudocode and flowcharts should express ideas and concepts in English. They are intended to be read by human beings, not compilers. There are several free options you can use to create your flowchart, such as Draw.io, Lucidchart, or Creately. Make sure to use a tool designed for creating flowcharts to ensure that you are using the appropriate symbols and shapes.
1. Consider the high-level architecture of your program and
eak it into categories like logic, user interaction, etc. Then think about how you might implement each category. Be sure that your solution takes into account all features and requirements.
2. Create the pseudocode for your program. Be sure to do the following:
· Use control structures.
· Use indentation and white space.
· Keep it simple and concise.
3. Create a flowchart for your program. Be sure to do the following:
· Use appropriate design elements such as start and end points, decision
anches, and so on.
· Use labels for all flowchart shapes and a
ows.
· Keep everything on one page for better readability.
4. Reflect on your design so far by reviewing your pseudocode and flowchart. Write a response that addresses the following questions:
· Does your program flow in a logical order?
· What variables are implied by your design? Do they account for everything in the problem statement?
· What sections of the code might make sense to put in main()? What pieces of the code would make sense in a function or functions?
· Which method do you prefer, the visual flowchart or the text-based pseudocode? Why?
