Sort an array: the Usort () function uses a user-defined function to sort the array, with the instance code as follows:

return 0; Returns
Some time ago, a function that needed to be done was to do the sorting of the file system. Because it is the model that you write, you define the data structure. The original idea was to implement a sorting algorithm for folders and filenames, but

Think of sorting every day, bubble, binary search, and the result comes with the sorting function sort and qsort in STL, finally saving yourself ~
So I summarized it myself. First, the sort function is shown in the following table:
// 1. sort by sort in ascending order:
#include#includeusing namespace std;int main(){ int a[10],i; for (i=0;i
// 2. Use sort to sort data in ascending order:
Add the CMP function. You can also modify the CMP function (Change '>' to
