9、插入排序

 1 #include<iostream>
 2 
 3 using namespace std;
 4 
 5 template<class T>//函数模板    应对多种类型的变量
 6 void InseartionSort(T *p, int n);
 7 
 8 int main()
 9 {
10     double a[] = { 2,4,6.5,8,1,3.8,5,7.4,9,0 };
11     InseartionSort(a, 10);
12     for (int i = 0; i < 10; i++)
13         cout << a[i]<<endl;
14     system("pause");
15     return 0;
16 
17 }
18 template<class T>
19 void InseartionSort(T *p, int n)
20 {
21     int in, out;
22     //out=0已经排好
23     for (out = 1; out < n; ++out)//++out与out++一样
24     {
25         T temp = p[out];
26         in = out;
27         while( p[in - 1] >= temp)
28         {
29             p[in] = p[in - 1];
30             --in;//--in与in--一样
31         }
32         p[in] = temp;
33     }
34 }
