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
BEGIN
// Step 1: Set the total monthly data allowance
SET totalAllowance = 50
// Step 2: Prompt the user to enter their data usage
DISPLAY "Enter the amount of data you have used this month (in GB): "
INPUT dataUsed
// Step 3: Calculate the remaining data
SET remainingData = totalAllowance - dataUsed
// Step 4: Check for negative remaining data
IF remainingData < 0 THEN
SET remainingData = 0
DISPLAY "You have exceeded your monthly data allowance."
ENDIF
// Step 5: Display the remaining data
DISPLAY "You have ", remainingData, " GB of data remaining this month."
END
📝 Explanation
This pseudocode provides a simple and clear process to help users track their monthly data usage relative to a standard data cap—here assumed to be 50 gigabytes (GB).
The program begins by initializing the monthly data allowance as a constant value (totalAllowance = 50). This represents the total amount of data the user is permitted to use within one billing cycle, such as a calendar month.
Next, it prompts the user to input how much data they have already used (dataUsed). This step involves reading an input value from the user, usually via keyboard entry, representing the current usage for the month in GB.
After obtaining the usage, the pseudocode calculates how much data the user has remaining by subtracting dataUsed from totalAllowance. This result is stored in the variable remainingData.
An additional check is included to handle situations where the user has used more than 50GB. If remainingData is negative (which means the user exceeded their limit), the value is set to 0, and a message notifies the user that they have gone over their allowance. This prevents displaying a negative remaining balance, which might confuse users.
Finally, the program displays the remaining data available for the rest of the month. This helps users monitor their consumption and avoid exceeding the limit, which could result in extra charges or reduced speeds, depending on their service provider.
This pseudocode emphasizes user input, conditional logic, and output display, forming the basis of many real-world data monitoring tools.
