Answer / susie

Answer :

Compiler error (at line number 4): size of v is Unknown.

Explanation:

You can create a variable of type void * but not of type
void, since void is an empty type. In the second line you
are creating variable vptr of type void * and v of type void
hence an error.

main() { int *j; { int i=10; j=&i; } printf("%d",*j); }
