‘壹’ c语言中如何输入年月日
就这么写的，没调试，你自己调一下好吧
#include <stdio.h>
void main()
{
int year,month,date;
scanf("%d-%d-%d",&year,&month,&date);
printf("%d-%d-%d",year,month,date);
if(year<0||year>3000)
printf("Error!");
if(month>12||month<1)
printf("Error!");
switch(month)
{
case 1: if(date>31||date<1) printf("Error!");break;
case 2: if((year%4==0)&&(year%100!=0)||(year%400==0))
{
if(date>29||date<1) printf("Error!");
}
else
if(date>28||date<1) printf("Error!");
break;
case 3: if(date>31||date<1) printf("Error!");break;
case 4: if(date>30||date<1) printf("Error!");break;
case 5: if(date>31||date<1) printf("Error!");break;
case 6: if(date>30||date<1) printf("Error!");break;
case 7: if(date>31||date<1) printf("Error!");break;
case 8: if(date>31||date<1) printf("Error!");break;
case 9: if(date>30||date<1) printf("Error!");break;
case 10: if(date>31||date<1) printf("Error!");break;
case 11: if(date>30||date<1) printf("Error!");break;
case 12: if(date>31||date<1) printf("Error!");break;
}
}
‘贰’ c语言编程：打印年历
基于你对问题的描述c语言编程：打印年历
可以跟我详细交流下

你看下吧
‘叁’ 闰年用c语言怎么写
1、打开Visual Studio编辑器，新建一个C语言文件，在最前面引入标准库文件，然后定义一个main主函数：
‘肆’ 用c语言编程：打印年历
没想到这个程序会做这么长，要不得多要点分。
#include <stdio.h>
void main()
{
int i,j,k,year,week;
int day[]={31,28,31,30,31,30,31,31,30,31,30,31};
char month[12][10]={"January","February","March","April","May","June","July","August","September","October","November","December"};
printf("Input year you want to print:");
scanf("%d",&year);
if((year%4==0&&year%100!=0)||(year%400==0)) day[1]++;
week=(35+year+year/4-year/100+year/400)%7; //计算当年的1月1日是周几的公式
for(i=0;i<12;i++)
{
printf("\n%s\n",month[i]);
printf("Sun Mon Tue Wed Thu Fri Sat\n");
for(k=0;k<week;k++) printf(" ");
for(j=1;j<=day[i];j++)
{
printf("%3d ",j);
if(++week>=7)
{
printf("\n");
week=week%7;
}
}
printf("\n");
}
}
