referencing arrays

[TheBeardedQuack]

Just a quick question because i wasn't sure how 32b or higher OSs define pointers.
My question is does a pointer refer to a 4byte memory block, or 1 specific byte.

//What would this return
char ar[8] = {33};
(&ar[0] == &ar[1])

My question is does a pointer refer to a 4byte memory block, or 1 specific byte.

It depends on the pointer's type.

A char is one byte. A pointer to a char points to 1 byte.

An int16_t is two bytes. A pointer to an int16_t points to two bytes.
