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 :

Here’s the pseudocode to prompt the user for the amount of data used in a month, calculate the remaining data, and display it:

Pseudocode:

BEGIN
    SET total_data_allowance = 50  // Total monthly data allowance in GB
    PROMPT "Enter the amount of data (in GB) you have used this month:"
    READ data_used  // User input for the amount of data used in GB

    IF data_used < 0 OR data_used > total_data_allowance THEN
        DISPLAY "Invalid input. Please enter a value between 0 and 50."
    ELSE
        SET remaining_data = total_data_allowance - data_used  // Calculate remaining data
        DISPLAY "You have " + remaining_data + " GB of data remaining this month."
    END IF
END

Explanation:

1. Initial Setup:
   The total monthly data allowance is set to 50GB, as specified in the problem. The program initializes a variable total_data_allowance to store this value.
2. Prompt for User Input:
   The program prompts the user to enter the amount of data they have used in the month. The data is then captured in the data_used variable.
3. Input Validation:
   The program checks whether the user input is valid. The input should be a value between 0 and 50, since the user cannot use more than 50GB in a month based on the allowance. If the input is outside this range, the program will notify the user with an error message.
4. Remaining Data Calculation:
   If the input is valid, the program calculates the remaining data by subtracting the data_used value from the total allowance (50GB).
5. Display Remaining Data:
   The program then displays the calculated remaining data to the user, giving them the number of gigabytes left in their allowance for the month.

Key Concepts:

• User Input Handling: The program handles user input through a prompt and reads the value entered.
• Basic Arithmetic: The program uses basic arithmetic to calculate the remaining data.
• Error Handling: The pseudocode includes input validation to ensure the user enters a reasonable value.

Here is the visual representation of the pseudocode for the data allowance calculation program. It clearly shows the steps involved, from prompting for user input to calculating and displaying the remaining data.
