1）③排序算法之插入排序[1]直接插入排序

 1 #include<iostream>
 2 using namespace std;

 4 int direct_sort(int n,int array[100]){//直接插入排序
 5     register int  i,temp;
 6     for(i=1;i<n;i++){
 7         temp=array[i];
 8         int j=i-1;
 9         while(array[j]>temp){
10             array[j+1]=array[j];
11             j--;
12         }
13         array[j+1]=temp;
14     }
15     return 0;
16 }

18 int print(int n,int array[100]){
19     int i;
20     for(i=0;i<n;i++){
21         cout<<array[i]<<" ";
22     }
23     cout<<endl;
24     return 0;
25 }
26 int main()
27 {
28     int array[10]={5,7,8,2,3,5,4,3,2,1};
29     direct_sort(10,array);
30     print(10,array);
