C语言结构体简单入门讲解

struct student
{
	char name[20]；
	char sex;
	int age;
	float grade;
}；

#include <stdio.h>
#include <string.h>
struct student
{
	char name[20];
	char sex[10];
	int age;
	float grade;
};

int main()
{
	//定义结构体变量
	//方法一，定义并初始化
	struct student stu={"李四","男",18,59.9};
	
	
	//方法二，先定义，后初始化
	struct student stu2;
	strcpy(stu2.name,"赵四");
	strcpy(stu2.sex,"女");
	stu2.age=19;
	stu2.grade=78;
	
	//方法三，指定成员初始化
	struct student stu3={.name="张三".age=17,.sex="男",.grade=90};

	//方法四，指定成员初始化
	struct student stu4={name:"吴强",age:21,sex:"男",grade:99};

	//打印信息
	printf("姓名是：%s\n",stu.name);
	printf("性别是：%s\n",stu.name);
	printf("年龄是：%d\n",stu.name);
	printf("成绩是：%f\n",stu.name);

	printf("姓名是：%s\n",stu2.name);
	printf("性别是：%s\n",stu2.name);
	printf("年龄是：%d\n",stu2.name);
	printf("成绩是：%f\n",stu2.name);

	printf("姓名是：%s\n",stu3.name);
	printf("性别是：%s\n",stu3.name);
