C结构体语法问题

C语言是一种广泛应用于系统开发和嵌入式设备编程的编程语言。在C语言中，结构体是一种自定义的数据类型，用于组织和存储不同类型的数据。本文将介绍一些与C结构体相关的语法问题，并提供一些案例代码以帮助读者更好地理解。

c
struct Person {
    char name[20];
    int age;
    float height;
};

c
#include 
int main() {
    struct Person person1;
    
    strcpy(person1.name, "John");
    person1.age = 25;
    person1.height = 1.75;
    
    printf("Name: %s\n", person1.name);
    printf("Age: %d\n", person1.age);
    printf("Height: %.2f\n", person1.height);
    
    return 0;
}

c
struct Date {
    int day;
    int month;
    int year;
};
struct Student {
    char name[20];
    struct Date birthdate;
};

c
#include 
int main() {
    struct Student student1;
    
    strcpy(student1.name, "Alice");
    student1.birthdate.day = 10;
    student1.birthdate.month = 5;
    student1.birthdate.year = 2000;
    
    printf("Name: %s\n", student1.name);
    printf("Birthdate: %d/%d/%d\n", student1.birthdate.day, student1.birthdate.month, student1.birthdate.year);
    
    return 0;
}
