c语言万年历程序。编写程序打印任意给定的日历php生成guid 源码年份的日历或者某年某月的月历或者查询某一天是星期几？
以下是一个示例的 C 代码，实现了打印给定年份的代码驱动过保护源码日历、某年某月的作日安卓心率源码月历以及查询某一天是星期几的功能：
#include <stdio.h>// 判断某年是否为闰年int isLeapYear(int year) {
if ((year % 4 == 0 && year % != 0) || year % == 0) {
return 1;
}
return 0;}// 获取某年某月的天数int getMonthDays(int year, int month) {
int days;
switch (month) {
case 2:
days = isLeapYear(year) ? : ;
break;
case 4:
case 6:
case 9:
case :
days = ;
break;
default:
days = ;
break;
}
return days;}// 计算某年某月1号是星期几int getWeekday(int year, int month) {
int d, m, y;
d = 1;

printf("========== %d 年日历 ==========\n", year);
