Example

// Created by www.example.com on 15/11/9. // Copyright © 2015 Example. All rights reserved. // #include<stdio.h> #define N 10 int main() { int a[N]={0,1,2,3,4,5,6,7,8,9}; int i,t; printf("Original array is:\n"); for(i=0;i<N;i++) printf("%d ",a[i]); for(i=0;i<N/2;i++) { t=a[i]; a[i]=a[N-1-i]; a[N-1-i]=t; } printf("\n Sorted array:\n"); for(i=0;i<N;i++) printf("%d ",a[i]); printf("\n"); return 0; }

The output of the above example is:

原始数组是:
0 1 2 3 4 5 6 7 8 9 
排序后的数组:
9 8 7 6 5 4 3 2 1 0
