实现效果如图:
大概分以下几个点：
代码如下:
#include<stdio.h>
int Leap_year[13] = {
0,31,29,31,30,31,30,31,31,30,31,30,31 };
int Com_year[13]={
0,31,28,31,30,31,30,31,31,30,31,30,31};
char Week[7][5] = {
"一","二","三","四","五","六","日" };
int year, month, day;
//用户输入日期
int User_Scanf()
{
printf("请输入年-月-日:");
while (scanf("%d-%d-%d", &year, &month, &day) != EOF)
{
//是否在有效范围内检查
if (year <= 0 || year >= 10000 || month < 0 || month >= 13 || day < 0 || day >= 31)
{
printf("Error!\n");
continue;
}
return 0;
}
}
//打印星期
void Print_Week()
{
printf("********************************************************\n");
printf("\t\t\t万年历\t\t\t\n");
for (int i = 0; i < 7; i++)
{
printf("%s\t", Week[i]);
}
printf("\n");
}
//判断闰/平年
int is_Leap_Com(int year)
{
if ((year % 4 == 0 && year % 100 != 0) || (year % 400 == 0))
{
return 1;//闰年
}
else
return 0;//平年
}
//计算天数
int Count_Day(int year,int month,int day,int Leap_year[],int Com_year[])
{
int sum = 0;
//计算年天数
if (is_Leap_Com(year) == 1)
{
sum += 366;//闰年
}
else
sum += 365;//平年
//计算月天数
if (is_Leap_Com(year) == 1)
{
for (int i = 1; i <=month; i++)
{
sum += Leap_year[i];//闰月
}
}
else
{
for (int i = 1; i <=month; i++)
{
sum += Com_year[i];//平月
}
}
return sum;
}
//打印日历
void Print_Day(int num, int year, int month)
{
int result = 0, temp = 0;
result = num % 7;//打印空格
for (int i = 0; i < result; i++)
{
printf("\t");
}
temp = 7 - result;//打印除空格外的日历
if (is_Leap_Com(year) == 1)
{
for (int i = 1; i <=Leap_year[month]; i++)
{
printf("%d\t", i);
if (i == temp || (i - temp) % 7 == 0)//判断是否换行
printf("\n");
}
}
else
{
for (int i = 1; i <=Com_year[month]; i++)
{
printf("%d\t", i);
if (i == temp || (i - temp) % 7 == 0)
printf("\n");
}
}
printf("\n");
printf("********************************************************\n");
}
int main()
{
User_Scanf();//用户输入日期
Print_Week();//打印星期
int num=Count_Day(year,month,day, Leap_year, Com_year);计算天数
Print_Day(num,year, month);//打印日历
return 0;
}
