一、结构体的声明
#include <stdio.h>
#include<stdlib.h>
struct student {
int num;
char sex;
int age;
struct student *next;
};
int main() {
int i = 0;
struct student std1, std2;
//std0={"",''0,std1};
std1.num = 1;
std1.sex = 'M';
std1.age = 24;
std1.next = &std2;
std2.num = 2;
std2.sex = 'w';
std2.age = 25;
std2.next = NULL;
printf("%d\n", std1.next->age);
system("pause");
}
二、结构体的操作
#include <stdio.h>
#include<stdlib.h>
struct student {
int num;
char sex;
int age;
struct student *next;
};
int main() {
int i = 0;
struct student *head = NULL;
struct student std1 = { 1,'m',19 };
struct student std2 = { 2,'w',21 };
struct student std3 = { 3,'m',23 };
struct student std4 = { 5,'m',2 };
head = &std1;
std1.next = &std2;
std2.next = &std3;
std3.next = NULL;
std1.next = &std4;
std4.next = &std2;
//查找年龄为a2的所在位置，及输出该位置的性别
while (head != NULL) {
i++;
if (head->age == 2) {
printf("%c,%d", head->sex, i);
break;
}
else { head = head->next; }
}
system("pause");
return 0;
}
