两日期间隔

给出两个时间输出他们间隔几天

如:

输入:

2013 1 1

2013 2 1

输出

31

代码如下:

#include<stdio.h>

  printf("%d\n",j-i);
 }
 else if(yca==1)

  { 
   i=366-cou(y[0],m[0],d[0]);
   j=cou(y[1],m[1],d[1]);
   printf("%d\n",i+j);
  }
  else if(lean(y[0])==0)
  {
   i=365-cou(y[0],m[0],d[0]);
   j=cou(y[1],m[1],d[1]);

  }
 }

  }
 }
 return 0;
}
int lean(int year)
{

  return 1;
 else
  return 0;
}
int cou(int nian,int yue,int ri)
{
 int k,count=0;
 for(k=1;k<yue;k++)
 {
  if(k==1||k==3||k==5||k==7||k==8||k==10||k==12)
