C语言生日题.

输入一个学生的生日(年:Y1,月M1,日D1),并输入当前日期(年Y2,月M 2,日D2),并求出该学生的年龄

这题代码恐怕会很长吧.
----------------解决方案--------------------------------------------------------
age = Y2-Y1
----------------解决方案--------------------------------------------------------
if (m2>=m1&&d1>=d2)
age=y2-y1;

else
age=y2-y1-1;
是不是题给错了?

呵呵,我理解错了.

应该是相差多少天?

写两个函数可以解决这个问题
1.判断是否闰年的函数
2.获取当前日期在这一年中是第几天的函数

----------------解决方案--------------------------------------------------------
# include <stdio.h>
void main ()
{
int year,month,day,y,m,d,age;
puts("input the brithday");
scanf ("%d%d%d",&year,&month,&day);
puts("input the date of today");
scanf ("%d%d%d",&y,&m,&d);
if (m<month||m==month&&d<day)

age=y-year-1;

else age=y-year;
printf ("age is %d\n",age);
}

题目是求相差的天数..不是年龄了..

我写的是不是太长了？？？
刚学不久 献丑了 哪里可以精简告诉我一下哈。。

#include<stdio.h>
int leapyear(int year)
{
if(!(year%4) && (year%100)) return 1;
else if(!(year%100) && !(year%400)) return 1;
return 0;
}
int checkdate(int year, int month, int day)
{
if(month<=12)
{
if(month<8)
{
if(month%2)

if(day<=31) return 1;
}
else if(2==month)
{
if(leapyear(year))
{
if(day<=29) return 1;
}
else if(day<=28) return 1;
}
else if(day<=30) return 1;
}

{
if(day<=30) return 1;
}
else
{
if(day<=31) return 1;
}
}
return 0;
}

printf("\nThanks for using!\n\nPress any key..\n");
getch();
}

return 1

这个怎么说呢?
