Option B (*ptNum++) first gets the value pointed to by ptNum and then increments the pointer to point to the next memory address. The other options either decrement the pointer or increment it before using its value. Option B (*ptNum++) uses the post-increment operator which means the current value pointed by ptNum will be used and then the pointer will be incremented by one.
