Ok, so first off I want to say that I am a newer programmer and I'm self taught. I'm currently trying to wrap my mind around how I would make a program (I'm using Kotlin) that would count the number of quarters out of a give value, and state the left over change.
so if I type input: 1.45
output will tell me:
5 quarters
0.20 Change
Now, I have done research on void methods, but I'm still confused on what that looks like. would anyone be willing to help me out on how id get started with this?
I mean like a quarter in terms of USD. So if you have $1.40 / $0.25 (quarter) = 5 Quarters and $0.20 left over. So I'm trying to make something that counts currency. I already have a weak code that calculates the math, but I need the number of quarters and left over change separated on 2 different lines of output.
You can do println to put each of the outputs on seperate lines
fun main() {
change(1.25)
changeWithNames(1.25)
}
fun change(x: Double) {
println(x.div(0.25).toInt()) // toInt to cut off the remainder
println(x.rem(0.25).toFloat()) // toFloat so that it rounds to the nearest hundreds place
}
fun changeWithNames(x: Double) {
println("${"%s".format(x.div(0.25).toInt())} quarters")
println("${"%.2f".format(x.rem(0.25))} Change")
}
fun changeWithDimes(x: Double) {
var q = x.div(0.25).toInt() // Quarters
var d = x.rem(0.25).div(0.10).toInt() // Dimes
var rem = (x - (q * 0.25 + d * 0.10)).toFloat() // Remainder
println(q)
println(d)
println(rem)
}
