结构数组与结构指针

结构数组：

struct student
{
   int idNumber;
   char name[15];
   int age;
   char department[20];
   float gpa;
};
……
student S[3]={ {428004, "Tomato",20, "ComputerScience",84.5},

{428005, "OOTTMA",20, "ComputerScience",85.0},
{428006, "OTA",20, "ComputerScience",89.8}

     };

跟一般数组用法一样。

结构指针：

student s1={428004, "Tomato",20, "ComputerScience",84.5}; //初始化结构变量
student *s1ptr=&s1; //定义结构指针变量，并把s1的地址赋值给s1ptr

void display(student *arg)
{
cout << "学号：" << arg->idNumber << "姓名：" << arg->name <<endl; //用箭头操作符访问成员数据
}
