Create A Flowchart And Pseudocode For Each Problem ✓ Solved

Create a flowchart and a pseudocode for each problem.

Instructions: Create a FLOWCHART and a PSEUDOCODE for each problem. Use the information below to create a pseudocode (which can be a text-based description for solving the problems) and a flowchart (using flowchart symbols to illustrate how you would program) to solve each problem.

1. Problem: Create a flowchart and pseudocode to do the following: You are going to modify week 4 assignment (2 problems) to use input() function (no hard coded values) to prompt the user to enter the values. Make sure the prompt message is meaningful, do not say "Enter value", say something like this "Enter hours worked" after you get all the inputs, display the results and prompt the user if wants more calculation (y/n). If no then print a message like "Thank you for ……." The flowchart must include a loop and if-then.

Paper For Above Instructions

Creating a flowchart and pseudocode are essential components in problem-solving within the realm of programming. These tools not only assist in visualizing logic but also help clarify the steps needed to solve a particular issue or automate a task. In this context, we will demonstrate how to develop pseudocode and a flowchart corresponding to a problem involving user input, output, and control flow.

Problem Overview

The goal is to develop a program that prompts users for input, processes that input, and then provides output based on the calculations. We will construct pseudocode and a corresponding flowchart that allows the user to input their "hours worked" and other relevant data, display the results, and prompt the user for further calculations.

Pseudocode

START


DECLARE continueCalculation AS STRING = "y"


WHILE continueCalculation = "y" DO


DISPLAY "Enter hours worked:"


INPUT hoursWorked


DISPLAY "Enter hourly rate:"


INPUT hourlyRate


SET totalPay = hoursWorked * hourlyRate


DISPLAY "Total Pay: ", totalPay


DISPLAY "Do you want to perform another calculation? (y/n)"


INPUT continueCalculation


END WHILE


DISPLAY "Thank you for using the program!"


END

Flowchart Description

The flowchart for the pseudocode provided illustrates the logic of the program. The flowchart includes the following components:

  • Start Node: Indicates the beginning of the process.
  • Input Nodes: Prompts for user input, such as hours worked and hourly rate.
  • Processing Node: Calculates total pay based on the provided inputs.
  • Output Node: Displays total pay to the user.
  • Decision Node: Asks the user if they want to perform another calculation.
  • End Node: Concludes the program with a thank you message.

Flowchart Symbols

The following flowchart symbols define the different actions in the flowchart:

  • Oval: Represents the start and end points.
  • Parallelogram: Used for input and output actions.
  • Rectangle: Represents processing steps (calculations).
  • Diamond: Indicates a decision point in the flow (conditional statements).

Step-by-Step Flowchart Construction

  1. Start with an oval shape labeled "Start".
  2. Draw an arrow to a parallelogram for input, labeled "Enter hours worked".
  3. Connect to another parallelogram labeled "Enter hourly rate".
  4. Create a rectangle for processing the total pay calculation.

  5. Draw an arrow to a parallelogram for output, labeled "Display Total Pay".

  6. Connect to a diamond for the decision: "Perform another calculation?"
  7. If 'yes', loop back to the input. If 'no', connect to an oval stating "Thank you for using the program!"
  8. End with an arrow from the last node back to the decision node.

Conclusion

Through creating the pseudocode and flowchart, we establish a clear and systematic approach to handling user input and output operations in programming. This exercise promotes understanding of fundamental programming concepts, such as loops and conditional logic, while fostering problem-solving skills essential for any programmer.
