void pointer behaviour ?

Hi,
I observed a strange behaviour (for me only) of void pointer. I wrote a code to access an integer through void pointer as below:

void *ptr;
int a[2] = {1,2};

ptr = (int *)&a;
ptr++; // This is giving error: Unknown Size

Why the above increment statement is giving error as i already cast the pointer to int type ?

Can anybody help me in understanding this ?
