在 C 语言中编写动态的生日祝福代码通常会涉及到字符串操作、输入输出以及时间日期处理。下面是一个简单的例子,该程序会让用户输入他们的出生日期,并在当前日期与用户生日之间做出比较,给出相应的祝福:
```c
#include <stdio.h>
#include <time.h>
#define BIRTHDAY_BANNER "Happy Birthday! May your day be filled with joy and laughter."
int main() {
// 获取当前日期
time_t now = time(0);
struct tm *current_time = localtime(&now);
// 用户输入生日年月日
int year, month, day;
printf("Please enter your birthday (YYYY-MM-DD): ");
scanf("%d-%d-%d", &year, &month, &day);
// 将输入转换成结构体 tm
struct tm birth_date = {0};
birth_date.tm_year = year - 1900; // 减去1900以便于与tm结构相符
birth_date.tm_mon = month - 1; // 月份从0开始计数
birth_date.tm_mday = day;
// 创建 tm 结构表示用户生日
mktime(&birth_date); // 转换为时间戳
// 比较两个日期
if (now > birth_date) {
time_t diff = now - birth_date;
printf(BIRTHDAY_BANNER "\nYou have %ld days until your next birthday.\n", diff / (60 * 60 * 24));
} else {
time_t diff = birth_date - now;
printf(BIRTHDAY_BANNER "\nToday is your %ldth day of the year!\n", diff / (60 * 60 * 24));
}
return 0;
}
```
