【结构体】

 

 1 #include <stdio.h>
 2 #include <string.h>
 3  
 4 struct Books
 5 {
 6    char  title[50];  //书名
 7    char  author[50];   //作者
 8    char  subject[100]; //科目
 9    int   book_id;        //ID
10 };
11  
12 int main( )
13 {
14    struct Books Book1;        /* 声明 Book1，类型为 Books */

16  
17    /* Book1 详述 */

结构体的使用方法
 1 #include <stdio.h>
 2 #include <string.h>

 4 struct Data
 5 {
 6    int i;
 7    float f;
 8    char  str[20];
 9 };
10  
11 int main( )
12 {
13     char a;
14    struct Data *data;        
15     data=&a;
16    data->i = 10;
17   printf( "data->i : %d\n", data->i);
