/*
?? ?*(a+1）就是a[1]，*(ptr-1)就是a[4],执行结果是2，5
&a+1不是首地址+1，系统会认为加一个a数组的偏移，是偏移了一个数组的大小（本例是5个int）
int *ptr=(int *)(&a+1);
则ptr实际是&(a[5]),也就是a+5
原因如下：
&a是数组指针，其类型为 int (*)[5];
而指针加1要根据指针类型加上一定的值，不同类型的指针+1之后增加的大小不同。
a是长度为5的int数组指针，所以要加 5*sizeof(int)
所以ptr实际是a[5]
但是prt与(&a+1)类型是不一样的(这点很重要)
所以prt-1只会减去sizeof(int*)
a,&a的地址是一样的，但意思不一样
?? ?a是数组首地址，也就是a[0]的地址，&a是对象（数组）首地址，
?? ?
?? ?a+1是数组下一元素的地址，即a[1],&a+1是下一个对象的地址，即a[5].
