[原创] C语言实现：万年历(1)

      经过近这几天的努力，终于写完了这个"万年历"的程序了，共享一下, 特别是同"勉"共享
[需求]
    请打印出任意年份的日历
[代码]
代码 #include <stdio.h>
#define LMonth 31
#define SMonth 30
#define VMonth 28
typedef enum {
Sun,
Mon,
Jue,
Wed,
Thu,
Fri,
Sat
} WEEK;
typedef enum {
January = 1,
February,
Match,
Apirl,
May,
June,
July,
August,
September,
October,
November,
December
} MONTH;
void printMonHead(void)
{
printf(" Sun Mon Jue Wed Thu Fri Sat\n");
}
void printMonth(const WEEK firstDay, int length )
{
WEEK weekDay = firstDay % 7;
int i;
printMonHead();
for (i=0; i<weekDay;++i)
{
printf(" ");
}
for(i=1;i<=length;++i)
{
weekDay = (++weekDay)%7;
printf("%7d", i);
if(weekDay==0) printf("\n");
}
printf("\n");
}
int isLeapYear(const int yr)
{
return ( yr%( yr%100 ? 4:400) ? 0 : 1);
}
int getYearDay(const int year)
{
int lastYear = year-1;
int yearNum = lastYear-1899;
int walker,counter=0;
for(walker=1900; walker < year; ++walker)
{
if(isLeapYear(walker)==1)
++counter;
}
return (365*yearNum+counter+1)%7;
}
void printYear(const int y)
{

int vDay = isLeapYear(y);
int monWeeks[13];

monLen[0]=0;
monLen[January]=31; monLen[February]=28+vDay; monLen[Match]=31;

monLen[July]=31; monLen[August]=31; monLen[September]=30;
monLen[October]=31; monLen[November]=30; monLen[December]=31;
monWeeks[0]=0;
monWeeks[January] = yDay;
monWeeks[February] = ((monWeeks[January] +monLen[January] )%7);
monWeeks[Match] = ((monWeeks[February] +monLen[February] )%7);
monWeeks[Apirl] = ((monWeeks[Match] +monLen[Match] )%7);
monWeeks[May] = ((monWeeks[Apirl] +monLen[Apirl] )%7);
monWeeks[June] = ((monWeeks[May] +monLen[May] )%7);
monWeeks[July] = ((monWeeks[June] +monLen[June] )%7);
monWeeks[August] = ((monWeeks[July] +monLen[July] )%7);
monWeeks[September] = ((monWeeks[August] +monLen[August] )%7);
monWeeks[October] = ((monWeeks[September] +monLen[September] )%7);
monWeeks[November] = ((monWeeks[October] +monLen[October] )%7);
monWeeks[December] = ((monWeeks[November] +monLen[November] )%7);




int i;
for(i=January; i<=December; ++i)
{
printf("\n-------------------------------------------------\n");
printf(" %d, %d \n",y,i);
printf("-------------------------------------------------\n");
printMonth(monWeeks[i],monLen[i]);
printf("\n");
}
return;
}
int main(void)
{
// int y3 = 2000;
// int y3 = 1946;
// printYear(y3);
int y;
int quit=0;
do
{
printf("Please enter which Year to Print For You (0 to quit): ");
scanf("%d",&y);
printf("\n");
if(y==0)
quit = 1;
else
printYear(y);
}while(!quit);
return 0;
}
[输出]
Please enter which Year to Print For You (0 to quit): 1973
Please enter which Year to Print For You (0 to quit): 1973
