C++中指向结构体变量的指针

#include<iostream>
#include<string>
using namespace std;
struct Candidate{
 string name;
 int count;
};
int main(){
 Candidate c_leader[2]={"Tom",5,"Marry",8};
 Candidate *p1,*p2;
 p1=c_leader;
 cout<<(*p1).name<<":"<<(*p1).count<<endl;
 p2=&c_leader[1];
 cout<<p2->name<<":"<<p2->count<<endl;
 return 0;
}

p1=c_leader;

#include<iostream>
#include<string>
using namespace std;
struct Candidate{
 string name;
 int count;
 Candidate *next;//定义了指向Candidate类型变量的指针
};
int main(){
    Candidate c_leader[3];
 c_leader[0].name="Tom";
 c_leader[0].count=5;
 c_leader[0].next=&c_leader[1];
 c_leader[1].name="Nick";
 c_leader[1].count=9;
 c_leader[1].next=&c_leader[2];
 c_leader[2].name="Jim";
 c_leader[2].count=10;
 c_leader[2].next=NULL;
 Candidate *p=c_leader;
 while(p!=NULL){
  cout<<p->name<<":"<<p->count<<endl;
  p=p->next;
 }
 return 0;
}
