What will be the output of this command?
string s="yes";
while (s=="yes")
{
for(int i=1;i<=5;i++)
{
Console.WriteLine("hello");
}
}

Indefinite loop:
while loop is an entry controlled loop.
we have specified "yes" as the entry point and no
exit point has been mentioned.So "hello" will keep
on executing till some terminator(ex: break) is used.
