What does the program print (lines separated by spaces)?

Console.Write("A");
Console.WriteLine("B");
Console.Write("C");
Console.WriteLine("D");

AB CD

Expecting A B C D: Write prints its text and leaves the cursor on the same line, so A and B end up together on the first line.
Expecting the line break before the text: WriteLine prints its text first and only then ends the line, so C starts the second line.
