4,访问结构体成员：

我们使用成员访问运算符（.）进行访问

//结构体练习

#include<stdio.h>

#include<string.h>

#include<iostream>

using namespace std;

struct Books {

       char tittle[50];

       char author[50];

       char subject[100];

       int book_id;

};

 

int main()

{

       struct Books book1;

       struct Books book2;

      

       strcpy(book1.tittle,"概率论与数理统计");

       strcpy(book1.author,"张六六") ;

       strcpy(book1.subject,"概论科学与技术");

       book1.book_id=121212;

      

       strcpy(book2.tittle,"计算机科学与技术");

       strcpy(book2.author,"张八八") ;

       strcpy(book2.subject,"交叉信息科学研究");

       book2.book_id=251212;

      

       cout<<book1.tittle<<endl;

       cout<<book1.author<<endl;

       cout<<book1.subject<<endl;

       cout<<book1.book_id<<endl;

       cout<<endl;

       cout<<book2.tittle<<endl;

       cout<<book2.author<<endl;

       cout<<book2.subject<<endl;

       cout<<book2.book_id<<endl;  

return 0;       

}

#include<iostream>
using namespace std;

	char tittle[50];
	char author[50];

	cout<<book2.author<<endl;
	cout<<book2.subject<<endl;
	cout<<book2.book_id<<endl;
	
return 0; 
	
}
