各位看看哪出了问题？无法输出天数。
程序代码：// ConsoleApplication2.cpp : 定义控制台应用程序的入口点。
//
#include <stdio.h>
#include<stdlib.h>
#include<string.h>
#include<time.h>
int main()
{
char id[] = "";
printf("enter your id:");
scanf("%s", &id);
printf("you born on %c%c%c%cyear%c%cmonth%c%cday\n", id[6], id[7], id[8], id[9], id[10], id[11], id[12], id[13]);
long nowyear, days, i,T;
char a[12] = { 31,29,31,30,31,30,31,30,31,31,31,30 };
printf("now is：");
T = id[10] * 10 + id[11];
days = id[12] * 10 + id[13];
scanf("%d", &nowyear);
if (nowyear % 4 == 0 && nowyear % 100 != 0)
{

}
else

}
for (i = 0; i < (id[10] * 10 + id[11] -1); i++)
days += a[i];

system("pause");
return 0;
}
