    p++ is faster because on compilation, it gets translated to three machine instructions, where as p=p+1 needs four machine instructions. All machine instructions take the same time.

    For p++, the instructions are:
    mov ax,
    inc ax
    mov,
    ax

    For p = p+ 1, the instructions would be,
    mov ax,
    mov bx, 1
    add bx
    mov,
    ax

    This is why p++ is faster than p+1
