(Bolded option is your answer)

1.Is there any difference between following declarations?

1 : extern int fun();

2 : int fun();

except extern

int fun(); is

probably in

another file

overrided with

extern int fun();

declaration, int

a = 20 is the

definition

declaration,

the definition

definition, a is

not defined
