How are local and global variables initialized by default?

Question

Based on below, am i right?

• global_A reference is initialized to null.
• global_int is 0
• local_A reference is null
• local_int is uninit

Answer 1

global_A reference is initialized to null.

No, its a valid object (constructed based on default constructor, which you don't have in your code but compiler adds that)

global_int is 0

yes

local_A reference is null

no, same reason as for global

local_int is uninitialized

no, its initialized to 0

Both global_A.x and local_A.x is uninitialized.

no both are initialized to 0
