一、结构的声明和初始化：写一个学生的结构体并打印出内容
1 #include<stdio.h>
2
3 struct student{
4 int id;
5 char name[10];
6 }stu1;
7
8 int main(){
9 stu1.id=110; // 赋值
10 strcpy(stu1.name,"zhangfei");
11 printf("%d,%s\n",stu1.id,stu1.name);
12
13 struct student stu2={112,"lisa"}; //初始化
14 printf("%d,%s\n",stu2.id,stu2.name);
15
16 return 0;
17 }
二、结构做参数
1 #include <stdio.h>
2 #include <string.h>
3 struct student{
4 int id;
5 char name[10];
6 }stu;
7
8
9 void print1(struct student stu){
10 printf("%d,%s\n",stu.id,stu.name);
11 }
12
13 void print2(struct student *p){
14 printf("%d,%s\n",p->id,p->name);
15 }
16
17
18 int main(){
19 stu.id=110;
20 strcpy(stu.name,"zhangfei");
21
22 struct student stu2={112,"lisa"};
23 print1(stu);
24 print2(&stu2);
25 return 0;
26 }
三、结构做返回值的代码
1 #include <stdio.h>
2 #include <string.h>
3 struct student{
4 int id;
5 char name[10];
6 };
7 struct student input1(){
8 struct student stu;
9 printf("please input your id：\n");
10 scanf("%d",&stu.id);
11 printf ("please input you name:\n");
12 scanf ("%s",&stu.name);
13 return stu;
14 }
15 void input2(struct student *p){
16 printf("please input your id： ");
17 scanf("%d",&p->id);
18 printf("please input your name: ");
19 scanf("%s",&p->name);
20 }
21 int main(){
22 struct student stu;
23 stu=input1();
24 printf("%d,%s\n",stu.id,stu.name);
25 input2(&stu);
26 printf("%d,%s\n",stu.id,stu.name);
27 return 0;
28 }
