⟩ Can you predict the output of the code below?
delegate void Iterator();
static void Main()
{
List iterators = new List();
For (int i = 0; i < 15; i++)
{
iterators.Add(delegate { Console.WriteLine(i); });
}
Foreach (var iterator in iterators)
{
iterator();
}
}
This program tests the prospective developer on their experience working with loops and delegates. At first glance, one would expect the program to output the numbers 0 to 15, fifteen times. Instead, the number 15 is printed fifteen times. Since the delegate is being added within the for loop, and because the delegate is only referencing the variable i instead of the value itself, the loop sets the value of the variable i to 15 before it is invoked within each delegate.
