一、输入年份，判断这一年时闰年还是平年
#include "stdio.h"
#include "public.h"
#define BASE 2000
/*
要求：输入年份出这一年的日历
参考：2000 1月1日 星期日
*/
// 结构体初始化
void DataStructInit(void)
date.year = 0;
date.month = 0;
date.month_day=0;
date.week = 0;
date.day = 0;
void main(void)
/*
char weeks1 = "sun" &weeks=100(weeks1内存) sun存在内存100处
char *weeks2(一级指针) *weeks2 = &weeks1 weeks2存在内存150处，weeks2 指向内存100处
char **weeks3(二级指针)
*/
// 用于保存星期几
char **weeks[] = "SUN", "MON", "TUE", "WED", "THU", "FRI", "SAT";
// 平年于闰年
unsigned int Year_Leap[2][12] =
31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31, // 平年
31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31, // 闰年
;
DataStructInit();
printf("Please enter the year:\\n");
scanf("%d", &date.year);
if ((date.year % 4 == 0 && date.year % 100 != 0) || date.year % 400 == 0)
leap = TRUE; // 瑞年
date.day = 366;
printf("这一年时闰年共有:%d天\\n",date.day);
else
leap = FALSE;
date.day = 365;
printf("这一年是平年共有:%d天\\n",date.day);
typedef struct
unsigned int year;
unsigned int month;
unsigned int month_day;
unsigned int week;
unsigned int day;
DATE;
DATE date;
// 判断 平年 or 闰年
unsigned int leap;
typedef enum LEAP_NON
FALSE = 0,
TRUE = !FALSE
;二、输出闰年 or 平年及对应月份的天数
#include "stdio.h"
#include "public.h"
#define BASE 2000
/*
要求：输入年份出这一年的日历
参考：2000 1月1日 星期日
*/
// 结构体初始化
void DataStructInit(void)
date.year = 0;
date.month = 0;
date.month_day=0;
date.week = 0;
date.day = 0;
void main(void)
/*
char weeks1 = "sun" &weeks=100(weeks1内存) sun存在内存100处
char *weeks2(一级指针) *weeks2 = &weeks1 weeks2存在内存150处，weeks2 指向内存100处
char **weeks3(二级指针)
*/
// 用于保存星期几
char **weeks[] = "SUN", "MON", "TUE", "WED", "THU", "FRI", "SAT";
// 平年于闰年
unsigned int Year_Leap[2][12] =
31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31, // 平年
31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31, // 闰年
;
DataStructInit();
printf("Please enter the year:\\n");
scanf("%d", &date.year);
if ((date.year % 4 == 0 && date.year % 100 != 0) || date.year % 400 == 0)
leap = TRUE; // 瑞年
date.day = 366;
printf("这一年时闰年共有:%d天\\n",date.day);
else
leap = FALSE;
date.day = 365;
printf("这一年是平年共有:%d天\\n",date.day);
// 12个月
for(;date.month<12;date.month++)
// 每个月的天数
for(date.month_day=0;date.month_day<Year_Leap[leap][date.month];date.month_day++)
printf(" %d ",date.month_day+1);
printf("\\n");
