what is wrong in the code????

Question

fun main() {
var isDownloaded = false

while(!isDownloaded){

println("File is downloaded")
}
}

Answer 1

That '!' means NOT.
So this code says:

while (not isDownloaded)
same as
while (isDownloaded = false)

print 'File is downloaded'

And isDownloaded is set to false!
And it will never changed in the while loop. So it's a never ending loop.

Answer 2

It's true that it would cause infinite loop, but if you're running the code in Code Playground, the runtime limit will prevent such code from running infinitely (and exhaust the system)

Answer 3

yes I know but why the compiler does not generate infinity, the problem is in the code or in the compiler
