Draw A Flowchart And Write Pseudocode To Represent The Logic Of A Prog

Draw a flowchart and write pseudocode to represent the logic of a program that allows the user to enter two values. The program outputs the product of the two values. Refer to the sample run below. Sample Run: (user entered data is in bold) Please enter the first number: 25 Please enter the second number: 2 25 * 2 is 50 This assignment must be submitted as a Microsoft Word compatible file. Examples of Word compatible documents are those with a .doc, .docx, or .rtf file extensions.

Introduction

The task at hand involves designing a simple program that prompts users to input two numerical values, calculates their product, and displays the result. To effectively represent this logic, both a flowchart and pseudocode are necessary. These tools provide visual and structured representations of the algorithm, facilitating understanding and implementation. While straightforward, this exercise highlights fundamental programming concepts such as user input, data processing, and output display.

Flowchart Design

The flowchart provides a graphical representation, illustrating the step-by-step logic of the program. It consists of standard symbols including ovals, parallelograms, and rectangles, connected by arrows signifying process flow.

Flowchart Steps:

1. Start: The program begins.

2. Prompt for First Number: Display a message asking the user to enter the first number.

3. Read First Number: Capture the user's input.

4. Prompt for Second Number: Display a message asking the user to enter the second number.

5. Read Second Number: Capture the second input.

6. Calculate Product: Multiply the two numbers.

7. Display Result: Output the product with an appropriate message.

8. End: The program terminates.

Flowchart Diagram (Description):

- Start (Oval)

- Input "Enter first number" (Parallelogram)

- Read first number (Parallelogram)

- Input "Enter second number" (Parallelogram)

- Read second number (Parallelogram)

- Process "Calculate product" (Rectangle)

- Output "first number * second number is result" (Parallelogram)

- End (Oval)

This visual simplifies understanding the sequential steps involved in the program.

Pseudocode Representation

Pseudocode serves as a structured, language-agnostic outline of the program's logic. It helps programmers visualize the sequence of actions required to implement the task.

```plaintext

Start

Display "Please enter the first number:"

Input firstNumber

Display "Please enter the second number:"

Input secondNumber

product ← firstNumber * secondNumber

Display firstNumber + " * " + secondNumber + " is " + product

End

```

In this pseudocode:

- The program prompts the user twice for input.

- It stores the inputs in variables `firstNumber` and `secondNumber`.

- It calculates the product and stores it in `product`.

- It then displays the operation and result in a formatted message.

Implementation Using Java as Example

Here is how the pseudocode translates into a basic Java program:

```java

import java.util.Scanner;

public class MultiplyNumbers {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

System.out.print("Please enter the first number: ");

int firstNumber = scanner.nextInt();

System.out.print("Please enter the second number: ");

int secondNumber = scanner.nextInt();

int product = firstNumber * secondNumber;

System.out.println(firstNumber + " * " + secondNumber + " is " + product);

scanner.close();

}

}

```

This code snippet demonstrates the direct implementation of the pseudocode logic in a programming language.

Conclusion

Designing a simple program for user input, data processing, and output display is foundational in programming education. The flowchart offers a visual understanding of procedural steps, while pseudocode provides a structured blueprint that can be adapted into various programming languages. By combining these representations, learners can better grasp the logic flow and transition smoothly into actual coding. This exercise also underscores the importance of clear and structured planning in software development, emphasizing readability and maintainability.
