Since the loop's condition for running is true it will never end naturally (meaning you would have to use the break keyword to stop it) and since the first line is continue which causes the loop to start over from line 1 it will never end up running the print statement on line 2 within the loop.

In other words the loop will just run the continue line indefinitively.

Hi there, Matthew! The code I believe you're referring to is this:

while(true)
{    
    continue;
    Console.WriteLine("Ribbit")
}

Console.WriteLine("Croak");

What we have here is an endless loop. It starts at the while and says while(true). This will always evaluate to true, so it starts running the code inside the curly braces. The continue tells the code to return to the top of the loop at while(true). It never makes it to the "Ribbit" part. it just keeps jumping right back up to the top. This means that it also never makes it out of the loop to the "Croak" part either. Hence, nothing will ever print out.

Hope this helps! :sparkles:
