小程序(作业)怎么错的呀?分析下三条语句`~~
#include "stdio.h "
main()/*输入年，月，日计算该日期是这年的第几天*/
{int n;
int year,month,date,days=0;

printf( "please input year,month,date:\t ");

scanf( "%d,%d,%d ",&year,&month,&date);

int a[2][12]={{31,28,31,30,31,30,31,31,30,31,30,31},{31,29,31,30,31,30,31,31,30,31,30,31}};
/*这一句说是表达式语法错误,我是按书上说的,对照了半天都没有看出错误来*/

for(n=0;n <month;n++)

{if((year%4==0&&year%400!=0)||(year%400==0))

days+=a[1][n]; /*这句是未定义的符号a,可是我不是定义了数组a 了吗 ?*/

else days+=a[0][n];}/*这句为无效间接操作错误*/

days+=date;

printf( "the days are:\t%d ",days);
}




[解决办法]
在Turbo C for Windows中你把int a[2][12]={{31,28,31,30,31,30,31,31,30,31,30,31},{31,29,31,30,31,30,31,31,30,31,30,31}};
这句放到前面定义即可
但是你的程序好像有问题
如果是month=1,那么days必然超过31
