这是函数实现

#include<iostream>
#include"List.h"
using namespace std;
int main()
{
    int m[]={11,12,13,14,15,16,17,18,19,20},i;
    Clist obj1,obj2;
    obj1.insert(0,m[0]);
    for(i=0;i<10;i++)
        obj1.insert(0,m[i]);
    obj1.output();
    return 0;
}
这是主函数

通过调试了，通不过编译，请大家帮忙看看，，，，，，，，，，，，，，，，，，，
