题目描述：

代码：

#include <iostream>#include <string.h>using namespace std;struct student{    int number;    char name[20];    student *next;};student *createlist(int n){    int i;    student *head=NULL;    student *p=NULL;    head=new student;    head->next=NULL;    p=head;    cin>>p->number>>p->name;    for(i=1;i<n;i++)    {        p->next=new student;        p=p->next;        p->next=NULL;        cin>>p->number>>p->name;    }    return head;}void searchstu(student *head,char *str){    student *current;    current=head;    while(current!=NULL)    {        if(!strcmp(current->name,str))        {            cout<<current->number<<endl;            break;        }        else        current=current->next;    }}void destroy(student *head){    student *p;    p=head;    while(head!=NULL)    {        p=head;        head=head->next;        delete p;    }}int main(){    int n;    char str[20];    student *head;    cin>>n;    head=createlist(n);    cin>>str;    searchstu(head,str);    destroy(head);    return 0;}
