这是一个“三天打鱼两天晒网”的程序

[努力奋发的小农]

#include<stdio.h>

struct date
{
int year;
int month;
int day;
};

void main()
{
struct date today,term;
int yearday, year,day;
printf("Enter year/month/day:");
scanf("%d%d%d",&today.year,&today.month,&today.day);
term.month=12;
term.day= 31;
for(yearday=0, year = 1990; year < today.year; year++)
{
term.year = year;
yearday += days(term);
}
yearday += days(today);
day = year % 5;
if(day > 0 && day < 4)
printf("He was fishing at that day.\n");
else
printf("He was sleeping at that day.\n");
}

days(struct day)
{
struct date day;
static int day_tab[2][13] = {{0,31,28,31,30,31,30,31,31,30,31,30,31},
{0,31,29,31,30,31,30,31,31,30,31,30,31},};
int i, lp;
lp = day.year % 4 == 0 && day.year % 100 != 0 || day.year % 400 == 0;
for(i = 1; i <day.month; i++)
day.day += day_tab[lp][i];
return (day.day);
}
谁能帮我纠错呢，调试时不知道哪里错，因为结构变量用得还不行，谢谢大虾们了！

楼主最好把你程序的逻辑说清楚了。或者自己单步调试看看

#include<stdio.h>

struct date  
{
	int year;
	int month;
	int day;
};


int days(struct date day) //函数返回值类型
{
	static int day_tab[2][13] = {{0,31,28,31,30,31,30,31,31,30,31,30,31},
	{0,31,29,31,30,31,30,31,31,30,31,30,31},};
	int i, lp;
	lp = day.year % 4 == 0 && day.year % 100 != 0 || day.year % 400 == 0;
	for(i = 1; i <day.month; i++)
		day.day += day_tab[lp][i];
	return (day.day);
}


int main(void)
{
	struct date today,term;
	int yearday, year,day;
	printf("Enter year/month/day:");
	scanf("%d%d%d",&today.year,&today.month,&today.day);
	term.month=12;
	term.day= 31;
	for(yearday=0, year = 1990; year < today.year; year++)
	{
		term.year = year;
		yearday += days(term);
	}
	yearday += days(today);
	day = year % 5;
	if(day > 0 && day < 4)
		printf("He was fishing at that day.\n");
	else  
		printf("He was sleeping at that day.\n");

	return 0;
}

我自己调试出来了，因为我后来又学习了一下这个知识点，谢谢你们哈

我用的是switch有点冗长，不好意思发了，这个问题我们老师给我们布置过，让我们判断某天到底是打渔还是晒网
