What will the program output with async/await: main prints A, calls saySomething (static, returns Task), delays 5 seconds, then D?

If in the main method there is a sequence:

Console.WriteLine("A");
saySomething(); // saySomething - async Task, inside there is await Task.Delay(5000)
Console.WriteLine("D");

then the program will output:

A
D

Because calling saySomething() without await starts an asynchronous task but does not wait for its completion. Therefore, Console.WriteLine("D") executes immediately after starting the task.

If you call await saySomething();, then the output will be:

A
(pause for 5 seconds)
D

Explanation: async/await allows writing asynchronous code where await pauses the method execution until the task completes, but without await, the task is started, and the method continues executing.
