Write a single-line "Hello World" program.

Does it work?

...

int x = 0;

(x, int y) = point;

...

What is the output of program:

var digits = new string[]

{ "one", "two", "three", "four", "five" };

var range = digits[^2..];

foreach (var digit in range)

Console.Write($"{digit} ");

• one two three

• four five

• four

• IndexOutOfRangeException trown

Is code inside if operator executed?

int a = 10;

if (a is >= 20 and <30 or >=5 and <11)

{// Some code}

• Yes

• No

• The code doesn't compile

We have constructed class:

public struct Coords<T>

{

public T X;

public T Y;

}

Are types Coords<int>, Coords<object> unmanaged?(since C# 8.0)

• Yes. Both are unmanaged.

• No. Neither are unmanaged.

• Coords<int> are unmanaged, Coords<object> are not unmanaged

• Coords<int> are not unmanaged, Coords<object> are unmanaged
