C assignment of int

When you see code like this in C, what's the order of assignment?

int i = 0, var1, var2;

I don't understand the syntax...

All of them are local variables , the only difference is i has been assigned a value zero whereas the values of var1 and var2 are unpredictable, they will have garbage values.

i is initialized to 0 whereas variables var1 and var2 are uninitialized and thus have unspecified values(if they are defined in a local scope).

Only i is assigned the value zero.

var1 and var2 are uninitialized.

There's no "assignment" in your code whatsoever. It is a declaration of three variables of type int, of which one is initialized with zero. The = symbol is an integral part of initialization syntax, it has nothing to do with any "assignment". And since there's only one initialization there, there's really no question about any "order".

If that doesn't answer your question, clarify it.

There is only one assignment (i=0), the rest are definitions.
