这是程序原文：
#include <iostream>
#include <string>
using namespace std;   
typedef struct node * pointer;
struct node{
    int co; //系数
    int exp;//指数
    struct node * next ;
};

typedef pointer lklist;
lklist node()
{
    pointer head,rear,s;
    int co;
    int exp;
    head=new node;
    rear=head;
    for(i=0;i<n;i++)
    {s=new node;
    cin>>s->co;
    cin>>s->exp;
    rear->next=s;
    rear=s;
    cout<<endl;
    }
    rear->next=NULL;
    return head;
}

void output(lklist head)
{pointer p;
p=head->next;
while(p->next)
{cout<<p->co<<"*x"<<p->exp<<endl;
}}


node * creat(node*head,int x)
{node*s;s=head->next;
while(s&&s->exp!=x)
{s=s->next;}
return s ;}


lklist add(lklist A,lklist B)
{pointerc,p,q,r;
q=B->next;
c=A;
while(q!=NULL)
{if(p=locate(a,q->exp))
{p->co=p->co+q->co;p->exp=p->exp;
q=q->next;}
else {r=new node;
r->co=q->co;
r->exp=q->exp;
r->next=c->next;
c->next=r;
q=q->next;}
return c;}


int main()
{lklist A,B,C;
A=creat();cout<<"A:";output(A);
B=creat();cout<<"B:";output(B);
c=add(A,B);
cout<<"C=A+B"<<endl<<"C:";output(C);
return 0;
}

建议先去学习基本语法在来写链表吧

看你的代码，基本语法你都还不会，比如：for(i=0;i<n;i++)
你有定义了吗？

建议先看看一些基础的书籍，打好基础先^_^
