c - Dereference void pointer

Question

Even after casting a void pointer, I am getting compilation error while dereferencing it. Could anyone please let me know the reason of this.

int lVNum = 2;
void *lVptr;
lVptr = (int*)&lVNum;

printf("
lVptr[60 ] is  %d 
",lVptr[1]);

Answer 1

It doesn't make sense to dereference a void pointer. How will the compiler interpret the memory that the pointer is pointing to? You need to cast the pointer to a proper type first:

int x = *(int*)lVptr;
