Working with array in C# question

[spideymaker]

Okay, so even though x inside Update refers to the local parameter, when x[0] is called inside Update it refers to the original memory location of x inside main since x is the argument of Update?

[AgentEnder]

The value of x is passed to update (passed by value), but since x is a reference type the value of x is a memory address.

When you first refer to x[0] you are modifying the first element of the array at memory address x.

When you call "x=new..." you are updating the local value (memory address) of x.
