② C语言程序设计；"已知2000年1月1日为星期六,请输入任一年的年份后,打印该年的年历" 怎么设计啊，速求老师
C语言程序如下：
#include<stdio.h>
#defineYES1/*定义符号常数“是”*/
#defineNO0/*定义符号常数“否”*/
/*函数isleap():判断某年是否闰年*/
intisleap(intyear)
{
intleap=NO;
if((year%4==0&&year%100!=0)||year%400==0)
leap=YES;
returnleap;
}
/*函数week_of_newyears_day():求元旦是星期几*/
intweek_of_newyears_day(intyear)
{
intn=year-1900;
n=n+(n-1)/4+1;
n=n%7;
returnn;
}
intmain(intargc,char*argv[])
{
intyear,month,day,weekday,len_of_month,i;
printf(" 请输入某年年份:");
scanf("%d",&year);
printf(" 请输入某年1月1日：");
scanf("%d",&weekday);
/*因为你的要求是已知2000年1月1日是星期六，所以这里不用week_of_newyears_day去求星期六了*/
/*weekday=week_of_newyears_day(year);求元旦是星期几*/
printf(" %d年 ",year);/*打印年份*/
for(month=1;month<=12;month=month+1)/*打印12个月的月历*/
{
printf(" %d月份 ",month);
printf("------------------------------------------------------ ");
printf("星期日星期一星期二星期三星期四星期五星期六 ");
printf("------------------------------------------------------ ");
for(i=0;i<weekday;i=i+1)/*找当月1日的打印位置*/
printf("");
if(month==4||month==6||month==9||month==11)
len_of_month=30;
elseif(month==2)
{
if(isleap(year))
len_of_month=29;
else
len_of_month=28;
}
else
len_of_month=31;
for(day=1;day<=len_of_month;day=day+1)/*打印当月日期*/
{
printf("%2d",day);
weekday=weekday+1;
if(weekday==7)/*打满一星期应换行*/
{
weekday=0;
printf(" ");
}
}
printf(" ");/*打完一月应换行*/
}
return0;
}
运行效果如图
③ 用c语言编写万年历，要求输出任意一年的某月，能显示出这个月的日历
1、首先要判断一个年份是闰年还是平年，用一个子程序来做。
