Write a pseudocode that

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:

✅ Pseudocode: Monthly Data Usage Tracker

BEGIN
    SET monthly_allowance TO 50

    DISPLAY "Enter the amount of data (in GB) you have used this month:"
    READ data_used

    IF data_used < 0 THEN
        DISPLAY "Invalid input. Data used cannot be negative."
    ELSE IF data_used > monthly_allowance THEN
        SET remaining_data TO 0
        DISPLAY "You have exceeded your 50GB allowance."
        DISPLAY "Remaining data: 0 GB"
    ELSE
        SET remaining_data TO monthly_allowance - data_used
        DISPLAY "You have " + remaining_data + " GB remaining this month."
    END IF
END

✅ Explanation

This pseudocode outlines a simple data tracking program that helps a user manage their monthly internet data usage. The program is built around a fixed monthly data allowance of 50 gigabytes (GB), which is common among many internet service providers.

Step-by-step explanation:

1. Monthly Allowance Setup:
   The program begins by setting a variable monthly_allowance to 50 GB, representing the total data available to the user for the month.
2. User Input:
   The program prompts the user to input how much data they have used. This input is stored in a variable named data_used.
3. Input Validation:
   The program includes basic input validation. It checks if the data_used is negative. Since negative data usage is illogical, the program notifies the user that the input is invalid.
4. Data Overage Handling:
   If the user has used more than 50GB, the program sets remaining_data to 0 and informs the user that they’ve exceeded their data limit. This is helpful in scenarios where users want to monitor overages or avoid extra charges.
5. Normal Case – Remaining Data Calculation:
   If the data used is within the allowed range (0–50GB), the program subtracts the data_used from the monthly_allowance and shows the user how much data is remaining.

This pseudocode demonstrates the logic of a real-world utility tool that could be part of a broader app or website to help users manage bandwidth usage efficiently. By including input validation and clear output messages, it provides a user-friendly experience and helps prevent errors in interpretation.
