Getting Input
Part of the Fundamentals section of Coddy's Kotlin journey. Lesson 42 of 93.
Challenge
EasyIn the previous lesson, you printed a welcome message. Now, extend your program to collect the bill information from the user.
After the welcome message, read three inputs and store them in variables:
- First input: the bill amount (read as a string, convert to
Double) - Second input: the tip percentage (read as a string, convert to
Int) - Third input: the number of people splitting the bill (read as a string, convert to
Int)
After reading the inputs, print them in the following format:
Welcome to Bill Split Calculator!
Bill amount: [billAmount]
Tip percentage: [tipPercentage]
Number of people: [numberOfPeople]For example, if the inputs are 85.50, 15, and 3, the output should be:
Welcome to Bill Split Calculator!
Bill amount: 85.5
Tip percentage: 15
Number of people: 3Input constraints: the bill and tip percentage are nonnegative, and the number of people is a positive integer. Numeric inputs are valid and finite.
Try it yourself
fun main() {
// TODO: Write your code below to print the welcome message
println("Welcome to Bill Split Calculator!")
