Whats wrong in this code?

Question

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

if(hours == 5)
{
println(5)

}
else if(hours > 5 && hours < 24 ){
var a = hours - 5;
print((a *0.5) + 5)

}

else if(hours > 24){
var a = hours - 24
println((a * 0.5) + 15)

}

else{
println(15)

}

}

Answer 1

It's else if not if else.

You need to multiply hours by 1.0 in your else statement because total is Double

Hours maybe more than 48 also and for each 24 hours, $15 will be pay so here you have to do

if (hours > 24) {
total = (hours / 24) * 15 + (hours % 24) * 0.5;
}

Answer 3

This is my code that pass all test.
Please check it .

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

var total: Double = 0.0

if(hours <= 0)
total = 0.0;

else if(hours <= 5)
total = hours * 1.0

else if(hours > 5 && hours < 24)
total = 5 + ((hours - 5) * 0.5)

else if(hours == 24)
total = 15.0

else if(hours > 24)
total = ((hours / 24) * 15) + ((hours % 24) * 0.5);

print(total)
}

No need to write 1.0. 1 will also work.

Look at this

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)
}

Answer 6

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

if(hours > 24){
total = (hours/24)*15 + (hours%24)*0.5
println(total)
}

if else(hours > 5 && hours < 24){
total = (hours - 5)*0.5 + 5
println(total)
}

else{
total = hours*1
println(total)
}

}

This is my final code , but some error is coming. Saying expecting parentheses
