I have to assume p is a pointer or contains the value of a pointer

so

(int *)p

casts p to be a pointer to an integer

*(int *)p

dereferences the pointer that is (int *)p, i.e. accesses the memory location referenced by (int *)p

*(int *)p = 2;

Sets the value of the memory location pointed to by the pointer (int *)p to 2


oh and please don't double post
