使用更加简单的c语言程序编写上面程序

以下是用更简洁的C语言编写的类似程序，减少了不必要的细节：

#include <stdio.h>
#define MAX_NAME_LENGTH 50
#define MAX_ADDR_LENGTH 100

typedef struct {
    int id;
    char name[MAX_NAME_LENGTH];
    int age;
    char addr[MAX_ADDR_LENGTH];
} Student;

// 设置学生信息
void set_student(Student *student, int id, const char *name, int age, const char *addr) {
    student->id = id;
    strncpy(student->name, name, MAX_NAME_LENGTH - 1); // 防止缓冲区溢出，用strncpy
    student->age = age;
    strncpy(student->addr, addr, MAX_ADDR_LENGTH - 1);
    student->addr[MAX_ADDR_LENGTH - 1] = '\0'; // 添加终止符
}

// 打印学生信息
void print_student(const Student *student) {
    printf("ID: %d\n", student->id);
    printf("姓名: %s\n", student->name);
    printf("年龄: %d\n", student->age);
    printf("地址: %s\n", student->addr);
}

int main() {
    // 创建并初始化学生
    char student_name[] = "张三";
    char student_addr[] = "北京市海淀区";
    Student student1 = {1001, student_name, 18, student_addr};
    
    // 打印学生信息
    print_student(&student1);

    return 0;
}
