数组

	int arr[] = { 1,2,3,4,5,6,7,8,9,0 };

	reverse(arr, arr + 5);//前5个数字逆序

	for (int i = 0; i < 10; i++)
	{
		cout << arr[i] << ",";
	}

输出：5,4,3,2,1,6,7,8,9,0,

vector容器

	vector<int> vec_iContainer = { 1,2,3,4,5,6,7,8,9,0 };

	reverse(vec_iContainer.begin(), vec_iContainer.end());
	for (int i = 0; i < vec_iContainer.size(); i++)
	{
		cout << vec_iContainer[i] << ",";
	}

输出：0,9,8,7,6,5,4,3,2,1,
