64. Pointer-ii

Question.3

A developer reads the third byte from a 32-bit register array using pointer arithmetic:

uint32_t regs[4] = {0x100, 0x200, 0x300, 0x400};
uint32_t *p = regs;
p += 3;

The developer expects p to point to the third byte of the array. Is this correct?

Select Answer

Yes — p now points 3 bytes into the array
No — p points to the fourth element (regs[3]), which is 12 bytes from the start
No — p points to the third element (regs[2])
Yes — but only on platforms where uint32_t is 1 byte
