指向结构体变量的指针

# include <iostream>

using namespace std;
struct student
{
 int id_num;
 char name[10];
};

int main()
{
student mike = {123,{'m','i','k','e','\0'}};
        student *one = &mike;
cout <<(*one).id_num<<" "<<(*one).name<<endl;
cout << one->id_num<<" "<< one->name<<endl;//前面这两种表达都一样。->是指                                                    // 向运算符(有指针的时候用)
return 0;

}
