计算一年中几月几日是第几天的函数
#include<stdio.h>main()
{
int sum_day(int month,int day);
int leap(int year);
int year,month,day,days,flag=1;
char c;
while(flag)
{
printf("\nInput date(year,month,day):\n");
scanf("%d%d%d",&year,&month,&day);
printf("\n%d-%d-%d",year,month,day);
days=sum_day(month,day);
if(leap(year)&&month>=3)
days=days+1;
printf("is the %d days in this year\n",days);
printf("if not continue press N or n:\n");
c=getchar();
if((c=='n')||(c=='N'))
exit();
else
flag=0;
}
}
int sum_day(int month,int day)
{
int day_month[13]={0,31,28,31,30,31,30,31,31,30,31,30,31};
int i;
for(i=1;i<month;i++)
day=day+day_month[i];
return(day);
}
int leap(int year)
{
int leap=0;
if((year%4==0&&year%100==0)||(year%400==0))
leap=1;
return(leap);
}
哪位大哥帮我看看上面的输入循环怎么是死的？？谢谢； c=getchar();这个语句怎么不执行？
