Please tell what is wrong in the following code????

Question

fun shippingCost(amount: Double, international: Boolean): Double {
if (international==true){
return((15/100)*amount)
if ((15/100)*amount>=50.0){
return (50.0)
}
}
else {
if (amount>=75){
return (0.0)
}
else{
return((1/10)*amount)
}
}
}
fun main(args: Array<String>) {
val total = readLine()!!.toDouble()
val international = readLine()!!.toBoolean()
println(shippingCost(total, international))
}

Sample case:true,199
Output is 0.0
Which is not correct.

Answer 1

KNOWLEDGE & LEARNING if you want people to use your code, copy it into the code playground and share it here.

Answer 2

You need to use floats to avoid losing decimals in calculations.
0.1,0.15
Also, you should return 50.0 before other value

Answer 3

fun shippingCost(amount: Double, international: Boolean): Double {
var fee : Double = 0.0
if (international==true) {
fee = 0.15 * amount
if (fee>50) fee=50.0
} else {
if (amount<75) {
fee = 0.10 * amount
}
}
return fee
}

Answer 4

Please try to run the code before suggesting a solution.
