C++动态数组的实现

 1 #include <iostream>
 2 using namespace std;
 3 int main()
 4 {
 5     int n;
 6     while(cin>>n)
 7     {
 8         int *p=new int[n+1];
 9         p[0]=0;
10         p[1]=1;
11         for(int i=2;i<=n;i++)
12         {
13             p[i]=p[i-1]+p[i-2];
14         }
15     cout<<p[n]<<endl;
16     }
17     return 0;
18 }
