经典排序之冒泡排序代码 

 1 #include <stdio.h>
 2 int main()
 3 {
 4     int i,j,k;
 5     int tem,length;
 6     int a[10]={2,24,3,19,45,12,1,66,34,7};
 7 //    length = a.length();
 8     length = 10;
 9     printf("Before ordered:\n");
10     for(i = 0; i < length; i++)
11     printf("%d ",*(a+i));
12     printf("\n\n");
13     for(i = 1; i < length; i++)
14     {
15        for(j = 0; j < length-i; j++)
16        {
17              if(a[j]>a[j+1])
18           {
19              tem = a[j];
20              a[j] = a[j+1];
21              a[j+1] = tem;
22           }
23 
24        }
25         printf("The %d time bubble order:\n",i);
26         for(k = 0; k < length; k++)
27         printf("%d ",*(a+k));
28         printf("\n\n");
29     }
30     printf("After ordered:\n");
31     for(i = 0; i < length; i++)
32     printf("%d ",*(a+i));
33     printf("\n");
34     return 0;
35 }

冒泡排序方法的复杂度为O（n）^2,每次冒泡找到最大（或最小）的数放到最后。
