数组与数组容器的区别

int main() {

	int a[5] = { 1,6,3,4,5 };
	int *ptr = (int*)(&a + 1);
	cout << &a + 1 <<endl;
	cout << &a  << endl;

	cout << *ptr << endl;
	cout << &ptr << endl;
	cout << *(ptr-1) << endl;
	cout << (a + 1) << endl;
	cout << *(ptr - 1) << endl;
	

	int m = -10;
	int *pd = &m;
	cout << &pd << endl;
	cout << *pd << endl;
	

	return 0;
}

　　运行结果

0000004D485FFB7C

结论：

取数组地址+1是加的是整个数组占的字节数
