Could someone teach me the answer to this question?

Question

What is the output of this code?
static int Vol(int x, int y=3, int z=1) {
return x*y*z;
}
static void Main(string[] args) {
Console.WriteLine(Vol(2, 4));
}

Answer 1

The answer is 8 because x = 2, y = 4, z = 1.
If we didn't pass any value to the parameter y, then the default value will be 3. In this case, variable y receives a value of 4, then y = 4 and variable z does not receive any value in calling method, default value of z will be used instead.
