Answer :

Compiler error: Cannot increment a void pointer

Explanation:

Void pointers are generic pointers and they can be used only
when the type is not known and as an intermediate address
storage type. No pointer arithmetic can be done on it and
you cannot apply indirection operator (*) on void pointers.

/*what is the output for*/ void main() { int r; printf("Naveen"); r=printf(); getch(); }
