Write a pseudocode that Prompts the user to enter the amount of data (in gigabytes) they have used in a month

Write a pseudocode that:

Prompts the user to enter the amount of data (in gigabytes) they have used in a month.
Calculates the remaining data from a 50GB monthly allowance.
Displays the remaining data to the user.

The correct answer and explanation is :

To calculate the remaining data from a 50GB monthly allowance after the user inputs their data usage, follow this pseudocode:

START
    SET monthly_allowance TO 50  // Total monthly data allowance in GB
    PROMPT "Enter the amount of data used this month (in GB): "
    GET data_used
    IF data_used < 0 THEN
        DISPLAY "Data used cannot be negative. Please enter a valid amount."
    ELSE IF data_used > monthly_allowance THEN
        DISPLAY "Data used exceeds monthly allowance. Please enter a valid amount."
    ELSE
        SET data_remaining TO monthly_allowance - data_used
        DISPLAY "Remaining data for the month: ", data_remaining, " GB"
    END IF
END

Explanation:

1. Initialization:

• Set monthly_allowance to 50GB, representing the user’s total monthly data allocation.

1. User Input:

• Prompt the user to enter the amount of data they have used during the month.
• Store the user’s input in the variable data_used.

1. Input Validation:

• Check if data_used is less than 0. If true, display an error message indicating that data usage cannot be negative.
• Check if data_used exceeds monthly_allowance. If true, display an error message indicating that the usage exceeds the monthly limit.

1. Calculation and Output:

• If the input is valid, calculate the remaining data by subtracting data_used from monthly_allowance.
• Display the remaining data available for the month.

Key Considerations:

• Data Validation: Ensuring that the user’s input is within the acceptable range (0 to 50GB) prevents errors and maintains data integrity.
• User Feedback: Providing clear messages helps the user understand the status of their data usage and any issues with their input.

Flowchart Representation:

To visualize the process, consider the following flowchart:

        END                        Yes
                                   v
                            +--------------------------+
                            | Display error message    |
                            +--------------------------+
                                   |
                                   v
                            +--------------------------+
                            | Calculate data_remaining  |
                            +--------------------------+
                                   |
                                   v
                            +--------------------------+
                            | Display data_remaining    |
                            +--------------------------+
                                   |
                                   v
                                END

Benefits of This Approach:

• User-Friendly: The program guides the user to provide valid input and informs them of any errors, enhancing the user experience.
• Robustness: By handling edge cases (negative usage and overage), the program ensures reliable operation under various scenarios.

This pseudocode and flowchart outline a straightforward method for calculating and displaying the remaining data from a monthly allowance based on user input.
