Parking Fee Problem

Question

I am wondering what's wrong with my code. No syntax errors as well. But it is showing 'No Output' for this code. It will be good if someone could help me out fix this.

CODE:-

```fun main(args: Array<String>) {
var hours = readLine()!!.toInt()
var total: Double = 0.0
if(hours<=5)
{
total=hours
println(total)
}
else if(hours>5&&hours<24)
{
total=5+((hours-5)*0.5)
println(total)
}
else if(hours>=24)
{
total=15*(hours/24)+((hours-24)*0.5)
println(total)
}

}
```

Here is my solution :

fun main(args: Array<String>) {
var hours = readLine()!!.toInt()
var total: Double = 0.0

if (hours > 24) {
total += 15 * (hours / 24) + 0.5 * (hours % 24)
} else if(hours < 24 && hours > 5) {
total += (hours - 5) * 0.5 + 5
} else {
total += hours * 1
}

println(total)
}

You are getting no output because there is an error.

hours is an integer and total is double so you can't directly assign integer to double. To resolve this issue just do like this

total= hours * 1.0

There should be % not - in case of 24 because suppose there is 49 hours and you have to pay 15 / hours so there will be 24 * 15 + (49 % 24) * 0.5 but if you use - then it would be 24 * 15 + (49 - 24) * 0.5 which is wrong.

So here is right solution

total = 15 * (hours / 24) + (hours % 24) * 0.5

Answer 4

I try to make as simple as i can.
This is mine

fun main(args: Array<String>) {
var hours = readLine()!!.toInt()
var total: Double = 0.0
if (hours <= 5){
total = hours * 1.0
}
else if (hours > 5 && hours <24){
total = 5.0+((hours-5.0)*0.5)
}
else{
total = ((hours/24)*15.0) + ((hours%24.0)*0.5)
}
println(total)
}

Answer 5

You can follow this approach :-

fun main(args: Array<String>) {
var hours = readLine()!!.toInt()
var total: Double = 0.0
var take:Double

total = when{
hours<=0 -> 0.0

hours<=5 -> hours*1.0

hours>5 && hours<24 -> hours*1.0 - (hours-5)*0.5

hours>=24 -> (hours/24*15) + (hours%24*0.5)

else -> 0.0

}

println(total)

}

Answer 6

fun main(args: Array<String>) {

var x = readLine()!!.toInt()
var y : Double = 0.5
when {
x <= 5 -> println( x*1 )
x > 5 && x < 24 -> println(2.5+(x*y))
x > 24 -> println( (x%24)*y + (x/24)*15)
}
}

Answer 7

Try this code out:-

fun main(args: Array<String>) {
var hours = readLine()!!.toInt()
var total: Double = 0.0
if(hours<=5){
total += hours
println(total)
}
else if(hours>5&&hours<24){
total += 5 + (hours - 5) * 0.5
println(total)
}
else if(hours==24){
total += 15
println(total)
}
else if(hours>24){
total += (hours/24)*15+(hours%24)*0.5
println(total)
}
}
