Total And Average

Part of the Fundamentals section of Coddy's GDScript journey. Lesson 87 of 92.

Challenge

Easy

Handle the choice 3, the total and the average of the expenses. Keep everything you wrote in the previous steps.

If the array of expenses is empty, print:

No expenses recorded yet.

Otherwise, print the total and the average on two lines. For the expenses 100, 200 and 300, the output is:

Total expense: 600.0
Average expense: 200.0

Try it yourself

extends Node

func _ready():
	print("Welcome to the Daily Expense Tracker!")

	# Display the menu once
	print("\nMenu:")
	print("1. Add a new expense")
	print("2. View all expenses")
	print("3. Calculate total and average expense")
	print("4. Clear all expenses")
	print("5. Exit")

	# An empty array for the expenses
	var expenses: Array[float] = []

	while true:
		# Get the choice of the user
		var choice := OS.read_string_from_stdin()

		if choice == "1":
			# Add a new expense
			var amount := float(OS.read_string_from_stdin())
			expenses.append(amount)
			print("Expense added successfully!")
		elif choice == "2":
			# View all expenses
			if expenses.is_empty():
				print("No expenses recorded yet.")
			else:
				print("Your expenses:")
				for i in range(expenses.size()):
					print(i + 1, ". ", expenses[i])
		elif choice == "5":
			# Exit the program
			print("Exiting the Daily Expense Tracker. Goodbye!")
			break
