Didnt understand the second fornatted string code. Console.WriteLine("x = {0}; y = {1}", x, y); Why x & y is 0 & 1?

Answer 1

x=0
y=1
Are your values right?
Now assume they are in an array [x,y]
Thus, array[0]=0, array[1]=1.
That is essentially what the braces do.
{num} returns the (num+1)th term in the list of arguments given behind.

I am bad at explaining :(

Answer 2

Let me see...

Answer 3

{0} and {1} are placeholders. {0} is the second argument so that would be x and {1} is the third agrument that would be y. Since the value of x and y are not included in your code. I cannot predict your output.

Have a look at this code
