Css 225 Module 2 Lab Activity Good Programming Habits

Within this document add pseudocode and flowcharts for problems 1, 2, and 3. Give naming scheme examples for problems 4, 5, and 6. Give found resources for problem 7 Practice Pseudocode and Flowcharts: For the flowcharts we will be using a web app for drawing: draw.io Write Pseudocode and draw flowcharts for the following programs: 1 – A program that prints “Hello World” to the screen. 2 – A program that asks the user for their name and greets them with their name. 3 – A program that asks the user for two numbers and gives the user the possibility to choose between computing the sum and computing the product. Naming Schemes You are writing a new program and want to use an obvious and consistent naming scheme for each variable you will create. 4 – A program that calculates the user's BMI (Body Mass Index). You will need to collect their height and weight. What would you name these input variables? What would you name the output variable? 5 – A program that checks if the user for their login and password and checks it against a database. What names would you give these variables? 6 – A program that automatically converts English text to Morse code and vice versa. What names would you give the variables in this program? Resources It is important to develop a list of resources you can use to help you solve problems. Do a web search and find three sources that have not been mentioned in the slides or books. 7 – 8 – 9 –

Paper For Above instruction

The development of good programming habits is fundamental to producing efficient, readable, and maintainable code. This paper addresses the specific tasks outlined in the module, including pseudocode and flowchart creation for basic programs, examples of variable naming schemes for more complex tasks, and resource identification for problem-solving. These elements collectively contribute to cultivating disciplined programming skills necessary for successful software development.

Pseudocode and Flowcharts for Basic Programs

The first three problems involve fundamental programming tasks: printing a message, personalizing interaction with user input, and performing calculations based on user choices. For these, structured pseudocode provides clear logic, while flowcharts offer visual representations of the control flow.

Problem 1: Print "Hello World"

Pseudocode:

START


DISPLAY "Hello World"


END

Flowchart:

The flowchart consists of a start block, an output/output display block with "Hello World", and an end block connected sequentially.

Problem 2: Greet User by Name

Pseudocode:

START


PROMPT "Enter your name"


READ user_name


DISPLAY "Hello, " + user_name


END

Flowchart:

Begin with a start node, proceed to an input node asking for the user's name, then an output node greeting the user, followed by an end node.

Problem 3: Calculate Sum or Product of Two Numbers

Pseudocode:

START


PROMPT "Enter first number"


READ num1


PROMPT "Enter second number"


READ num2


PROMPT "Type 'sum' to add or 'product' to multiply"


READ choice


IF choice equals "sum" THEN


SET result = num1 + num2


ELSE IF choice equals "product" THEN


SET result = num1 * num2


ELSE


DISPLAY "Invalid choice"


STOP


ENDIF


DISPLAY result


END

Variable Naming Schemes for Programming Tasks

Adopting clear, consistent variable naming conventions enhances code readability and maintainability. Here are suggested naming schemes for the given problems:

Problem 4: Calculating BMI

  • Height input variable: userHeightMeters or heightInMeters
  • Weight input variable: userWeightKg or weightInKilograms
  • Output BMI variable: bodyMassIndex or BMI

Problem 5: Login Credentials Check

  • Username variable: userName
  • Password variable: userPassword
  • Database username: dbUserName
  • Database password: dbPassword

Problem 6: Text to Morse Code Conversion

  • English text input: englishText
  • Morse code output/input: morseCode
  • Conversion direction indicator: conversionMode or direction

Resources for Problem Solving

Effective problem-solving in programming relies on consulting credible sources. Here are three valuable resources beyond standard textbooks and lecture slides:

  1. Stack Overflow: A vast community where programmers ask and answer coding questions across numerous languages and topics.
  2. MDN Web Docs: Comprehensive documentation for web technologies including HTML, CSS, JavaScript, and APIs, useful for building web-based programs and understanding fundamental concepts.
  3. W3Schools: An accessible resource for tutorials, syntax references, and examples for various programming languages, especially for introductory and web development topics.

These resources serve as valuable tools for troubleshooting, learning new programming techniques, and ensuring adherence to best practices.

Conclusion

Developing disciplined programming habits involves structured problem-solving through pseudocode and flowcharts, applying clear variable naming conventions, and leveraging credible resources. Understanding these foundational elements ensures the creation of effective, readable, and maintainable code that aligns with professional software development standards. As developers practice these habits, they enhance their ability to tackle increasingly complex programming challenges with confidence and clarity.
