应用C++对一个存储在电脑桌面的名叫data.txt的文件中10033个整数包含正数和负数分别采用冒泡排序、插入排序、选择排序、希尔排序、归并排序、快速排序、堆排序和基数排序八种排序方法都进行从大到小和从小到大进行排序，将采用冒泡排序、插入排序、选择排序、希尔排序、归并排序、快速排序、堆排序和基数排序八种排序方法结果分别输出到对应的8个txt文件中，分别命名为冒泡排序、插入排序、选择排序、希尔排序、归并排序、快速排序、堆排序和基数排序。

好的，下面是C++代码示例，可以实现你的需求：

请将代码中的`C:\\Users\\用户名\\Desktop\\data.txt`替换为`data.txt`文件的实际路径，并将每个排序结果的输出路径替换为你想要存储结果的路径。然后，编译并运行该代码，它将按要求进行排序并将结果写入相应的txt文件中。
