Answer :

Linker Error : Undefined symbol '_i'

Explanation:

extern storage class in the following declaration,

extern int i;

specifies to the compiler that the memory for i is allocated
in some other program and that address will be given to the
current program at the time of linking. But linker finds
that no other variable of name i is available in any other
program with memory space allocated for it. Hence a linker
error has occurred .
