C写界面不好
你用delphi或者vb很简单的

哈哈,我编的第一个正经的程序就是这个程序了!
我自己编出来的,超爽啊!
#include
int leap (int year)
{if(year%4==0&&year%100!=0||year%400==0)
return 1;
else return 0;
}
int days_month (int month,int year)
{
if(month==1||month==3||month==5||month==7||month==8||month==10||month==12)
return 31;
if(month==4||month==6||month==9||month==11)
return 30;
if(month==2&&leap(year)==1) return 29;
else return 28;
}
int firstday(int month,int year)
{int w;
w=(1+2*month+3*(month+1)/5+year+year/4+year/400-year/100)%7+1;
return w;
}
main()
{int i,j=1,k=1,a,b,month,year;
printf("\n input month and year:\n");
scanf("%d%d",&month,&year);
b=days_month(month,year);
a=firstday (month,year);
printf(" Sun Mon Tue Wed Thu Fri Sat \n");
if(a==7)
{for(i=1;i<=b;i++)
{printf("%4d",i);
if(i%7==0)
{printf("\n");
}
}
}
if(a!=7)
{while (j<=4*a)
{printf(" ");
j++;
}
for(i=1;i<=b;i++)
{printf("%4d",i);
if(i==7*k-a)
{printf("\n");
k++;
}
}
}
getch();
