c语言结构体指针使用

一、代码

#define _CRT_SECURE_NO_WARNINGS
#include<stdio.h>
#include<string.h>
#include<stdlib.h>

struct student1
{
	char* name;
	int age;
	char* sex;
	int* score;
	char* addr;
};
typedef struct student1 ss;
int main(void) {

	ss* stu = (ss*)malloc(sizeof(ss)* 3);
	for (int i = 0; i < 3;i++) {
		(stu + i)->name = (char*)malloc(sizeof(char) * 21);
		(stu + i)->sex = (char*)malloc(sizeof(char)* 1);
		(stu + i)->score = (int*)malloc(sizeof(int)* 3);
		(stu + i)->addr = (char*)malloc(sizeof(char)* 51);
	}
	
	for (int i = 0; i < 3; i++)
	{
		scanf("%s%d%s%d%d%d%s",(stu+i)->name,&((stu+i)->age),(stu+i)->sex,&((stu+i)->score[0]), &((stu + i)->score[1]), &((stu + i)->score[2]),(stu+i)->addr);
	}

	for (int i = 0; i < 3; i++)
	{
		printf("姓名:%s\n", stu[i].name);
		printf("年龄:%d\n", stu[i].age);
		printf("性别:%s\n", stu[i].sex);
		printf("语文:%d\n", stu[i].score[0]);
		printf("数学:%d\n", stu[i].score[1]);
		printf("英语:%d\n", stu[i].score[2]);
		printf("家庭住址:%s\n", stu[i].addr);
		puts("");

	}
	
	//最后别忘记用free释放开辟的空间
	return 0;
}
