4.在game.c文件中编写查询年月的M_calendar函数
先上图
思路：
1.创建calendar.h文件，声明函数
2.创建calendar.c文件，编写查询函数（先编写查询年份的函数，再编写查询年月的函数）
3.创建test.c文件，运行主函数
步骤：
1.在test.c文件中设置全局变量和menu()函数，进行查询选项
#include "calendar.h"//两个源文件都要引用头文件
void menu()
{
printf(" ***********************************************\n");
printf(" ****************** 1.查询某年 *************\n");
printf(" ****************** 2.查询某年某月 *************\n");
printf(" ****************** 0.退出查询 *************\n");
printf(" ***********************************************\n");
}
int main()
{
int input;
int year, mon;
do
{
menu();
printf("\n请选择：>");
scanf("%d", &input);
system("cls");
switch (input)
{
case 1:
printf("请输入需要查询的年份：>");
while (~scanf("%d", &year))
{
system("cls");
if (year >= 1)
{
//Calendar(year);//查询年份的函数
printf("请输入需要查询的年份：>");
}
else
{
printf("查询超出范围，请重新输入：>");
}
}
break;
case 2:
printf("请输入需要查询的年月：>");
while(~scanf("%4d%2d", &year, &mon))
{
if (year >= 1)
{
//M_calendar(year, mon);//查询年月的函数
printf("\n请输入需要查询的年月：>");
}
else
{
printf("查询超出范围，请重新输入：>");
}
}
break;
case 0:
break;
default:
printf("输入错误，请重新选择：>");
break;
}
} while (input);
return 0;
}2.在calenda.h头文件中声明函数
#include <stdio.h>
#include <stdlib.h>
int is_leap(int year);//判断闰年
long days(int year);//计算某年与公元1年之间天数
long m_days(int year, int mon, int leap[], int common[]);//计算某年某月与公元1年之间天数
void display(int year, long sum, int leap[], int common[], char month[12][8]);//查询年份打印
void show(int year, int mon, long sum, int leap[], int common[], char month[12][8]);//查询年月打印3.在game.c文件中编写Calendar函数查询年份
3.1编写判断闰年的is_leap函数
int is_leap(int year)
{
if (year % 4 == 0 && year % 100 != 0 || year % 400 == 0)
{
return 1;
}
return 0;
}3.2编写计算查询年份和公元1年之间天数的days函数
long days(int year)
{
int i;
long sum = 0;
for (i = 1; i < year; i++)
{
if (is_leap(i) == 1)
{
sum += 366;
}
else
{
sum += 365;
}
}
return sum;
}3.3编写打印查询年份12个月日期的display函数
void display(int year, long sum, int leap[], int common[], char month[12][8])
{
int ret = sum % 7;
int temp = 7 - ret;
int i;
int mon = 0;
printf(" 万年历——%d年\n",year);
printf(" ***********************************************\n");
do
{
printf(" %6s\n", month[mon]);
printf("--------------------------------------------------\n");
char week[7][5] = { "周一","周二","周三","周四","周五","周六","周日" };
for (i = 0; i < 7; i++)
{
printf("|%5s ", week[i]);
}
printf("|\n");
for (i = 0; i < 7; i++)
{
printf("|------");//打印出'|'和'------'符号是为了美观，可省略
}
printf("|\n");
for (i = 0; i < ret; i++)
{
printf("| ");
}
if (is_leap(year) == 1)
{
for (i = 1; i <= leap[mon]; i++)
{
printf("|%4d ", i);
if (i == temp || (i - temp) % 7 == 0)
{
printf("|\n");
int j;
for (j = 0; j < 7; j++)
{
printf("|------");
}
printf("|\n");
}
}
ret = (leap[mon] % 7 + ret) % 7;
temp = 7 - ret;
if ((ret + leap[mon]) % 7 != 0)
{
printf("|\n");
}
for (i = 0; i < ret; i++)
{
printf("|------");
}
if (ret != 0)
{
printf("|\n");
}
}
else
{
for (i = 1; i <= common[mon]; i++)
{
printf("|%4d ", i);
if (i == temp || (i - temp) % 7 == 0)
{
printf("|\n");
int j;
for (j = 0; j < 7; j++)
{
printf("|------");
}
printf("|\n");
}
}
if ((ret + common[mon]) % 7 != 0)
{
printf("|\n");
}
ret = (common[mon] % 7 + ret) % 7;
temp = 7 - ret;
for (i = 0; i < ret; i++)
{
printf("|------");
}
if (ret != 0)
{
printf("|\n");
}
}
printf("\n");
mon++;
} while (mon < 12);
printf(" ***********************************************\n");
printf(" 万年历——%d年\n", year);
}4.在game.c文件中编写查询年月的M_calendar函数
4.1编写查询某年某月距离公元1年之间天数的m_days函数
long m_days(int year, int mon, int leap[], int common[])
{
long sum = days(year);
int i;
if (is_leap(year) == 1)
{
for (i = 0; i < mon - 1; i++)
{
sum += leap[i];
}
}
else
{
for (i = 0; i < mon - 1; i++)
{
sum += common[i];
}
}
return sum;
}4.2编写打印查询的某年某月的show函数
void show(int year, int mon, long sum, int leap[], int common[], char month[12][8])
{
int ret = sum % 7;
int temp = 7 - ret;
int i;
printf("\n %6s\n", month[mon - 1]);
printf("--------------------------------------------------\n");
char week[7][5] = { "周一","周二","周三","周四","周五","周六","周日" };
for (i = 0; i < 7; i++)
{
printf("|%5s ", week[i]);
}
printf("|\n");
for (i = 0; i < 7; i++)
{
printf("|------");
}
printf("|\n");
for (i = 0; i < ret; i++)
{
printf("| ");
}
if (is_leap(year) == 1)
{
for (i = 1; i <= leap[mon - 1]; i++)
{
printf("|%4d ", i);
if (i == temp || (i - temp) % 7 == 0)
{
printf("|\n");
int j;
for (j = 0; j < 7; j++)
{
printf("|------");
}
printf("|\n");
}
}
if ((ret + leap[mon - 1]) % 7 != 0)
{
printf("|\n");
}
ret = ((leap[mon - 1]) % 7 + ret) % 7;
for (i = 0; i < ret; i++)
{
printf("|------");
}
if (ret != 0)
{
printf("|\n");
}
}
else
{
for (i = 1; i <= common[mon - 1]; i++)
{
printf("|%4d ", i);
