Hav an example with an int pointer,
assume compiler allocates two bytes for an int.
int *iptr, iArray[3] = {1, 2, 3};
/*say the iArray starting address would be 1000*/
iptr = iArray[0];
/*When u r trying to do iptr++ then it will point to 1002
(two bytes for an int) where element 2 available.
cos compiler knows how many bytes has two increment*/
iptr++;
Now come to void:
void pointer is generic pointer which can be point to any
kind of data types.
void *ptr;
/*When u r trying to do ptr++, since it is void pointer, it
will not know exactly how many bytes has to be incremented.
So that arithmatic operations not possible with void
pointer.*/
