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:
javaCopyEditSTART
// Step 1: Define monthly data allowance
SET monthlyAllowance = 50
// Step 2: Prompt the user to enter the amount of data used
DISPLAY "Enter the amount of data used this month (in GB):"
READ dataUsed
// Step 3: Calculate the remaining data
SET remainingData = monthlyAllowance - dataUsed
// Step 4: Display the remaining data
DISPLAY "You have", remainingData, "GB of data remaining for this month."
END
Explanation (300 words):
The pseudocode above represents a simple program designed to help users track their data usage against a monthly data allowance. It follows a clear and structured flow using fundamental programming concepts such as variables, input/output, and arithmetic operations.
The pseudocode begins with a START and ends with an END, denoting the boundaries of the program. The variable monthlyAllowance is initialized with the value 50, representing a 50 GB monthly data cap. This is a constant value and remains unchanged throughout the execution.
Next, the program uses DISPLAY to prompt the user to input how much data they have used during the current month. The READ command stores the user’s input in a variable named dataUsed.
Once the data usage is inputted, the program calculates how much data is left using a simple subtraction operation: remainingData = monthlyAllowance - dataUsed. This calculation subtracts the user’s reported usage from the 50 GB limit to determine the remaining data.
Finally, the program displays the result using another DISPLAY command. It informs the user how many gigabytes they have left for the month.
This pseudocode is useful for beginners because it demonstrates how a basic input/output operation can be combined with arithmetic to solve a real-world problem. It can easily be converted into any programming language such as Python, Java, or C++. The simplicity of the logic makes it ideal for educational purposes, teaching students how to process user input and perform calculations with conditional logic if needed (e.g., warning the user if data is overused).
