【c++】C++ 动态分配内存

#include <iostream>
using namespace std;
void main()
{
int *f,n;
cout<<"Please input n=?";
cin>>n;
f=new int[n+1];//为动态数组f分配n+1个内存单元
if(f==0||n<1)
{
cout<<"Heap Error or Input Error!/n";
exit(0);
}
f[0]=f[1]=1;
cout<<f[0]<<endl<<f[1]<<endl;
for(int i=2;i<=n;i++)
{
f[i]=f[i-2]+f[i-1];
cout<<f[i]<<endl;
}
delete []f;
}
