(Spoiler Alert) Module 3's Final Question

Question

"What is the output of this code?

static int Test(out int x, int y=4)
{
x = 6;
return x * y;
}

static void Main(string[] args)
{
int a;
int z = Test(out a);
Console.WriteLine(a + z);
}"

I don't think I understand how this comes out to the answer it does.
Please correct me if I'm wrong...

I get that: "Test(out a)" will retrieve the value of "x * y", as that is the return statement.
Which is 6 * 4 = 24, this will be assigned to "int z".

However; I don't understand how "int a" gets a value.

I'm not the best coder here, so please - if you can - break it down simplistically.
Thankx in advance.

(Obviously no quotations, but I figured that was necessary since I copy/pasted the problem.
Also it makes it easier to read when explaining (I think)).

Answer 1

Variable a gets a value in method Test.
There is statement x = 6; in the definition of method, and when you call this method, you send variable a as output parameter, wich is x in definition, so a = 6.

Answer 2

a will take the value of out x which will be 6 --> so a=6
z will take the value of the function test which is x * y which is 6 * 4 = 24
so, z = 24
so, a + z = 6 + 24 = 30

Answer 3

answer:
30

Answer 4

The Test method assigns x to a. X=6, X=A, A=6.

int a = 6

int z = (6*4) = 24 //since y is 4 by default, Test(out a) really reads Test(out a, 4)

int (a+z) = 30

Answer 5

Answer 6

WRONG, YOUR BAD EZ KID

Answer 7

thanks dod

Answer 8

Nice

Answer 9

To find the largest of two variables
int a=42;
int b=88;
(a>b)
