原题目：某人从2010年1月1日起开始“三天打鱼两天晒网”，问这个人在以后的某一天中是“打鱼”还是“晒网”。

以下是程序源代码，初学者可能在很多地方不是很完善。

#include<stdio.h>struct fish{};int year;int month;int day;int i;//闰年int j = 0;//闰年个数int k = 0;//平年个数int y_s, m_s;//年月差int t = 0;//总日差int r = 0;//判断打渔晒网//判断年份int judge(){if (year < 2010)//判断年分输入是否正确{printf_s("year error!\n");return 0;}else{if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0)//判断闰年{i = 1;}else{i = 0;}}return 1;}//计算年份void count(){j = (year - 2010) / 4;//计算闰年个数k = (year - 2010) - j;//计算平年个数y_s = 366 * j + 365 * k;//计算年份差}//判断月份差int j_m(){judge();if (i = 1){switch (month)//计算月份差{case 1:m_s = 0;break;case 2:m_s = 31;break;case 3:m_s = 59;break;case 4:m_s = 90;break;case 5:m_s = 120;break;case 6:m_s = 151;break;case 7:m_s = 181;break;case 8:m_s = 212;break;case 9:m_s = 243;break;case 10:m_s = 273;break;case 11:m_s = 304;break;case 12:m_s = 334;break;default:printf_s("month error!\n");return 0;break;}}if (i = 0){switch (month)//计算月份差{case 1:m_s = 0;break;case 2:m_s = 31;break;case 3:m_s = 58;break;case 4:m_s = 89;break;case 5:m_s = 119;break;case 6:m_s = 150;break;case 7:m_s = 180;break;case 8:m_s = 211;break;case 9:m_s = 242;break;case 10:m_s = 272;break;case 11:m_s = 303;break;case 12:m_s = 333;break;default:printf_s("month error!\n");return 0;break;}}return 1;}//判断打渔晒网void reckon(){t = y_s + m_s + day;r = t % 5;switch (r)//判断打渔晒网{case 0:printf_s("今天晒网\n");break;case 1:case 2:case 3:printf_s("今天打渔\n");break;case 4:printf_s("今天晒网\n");break;}}//判断日子void j_d(){if (month == 1 || month == 3 || month == 5 || month == 7 || month == 8 || month == 10 || month == 12  ){if (day<1||day>31){printf_s("day error!\n");}else{reckon();}}else{if (month == 4 || month == 6 || month == 9 || month == 11){if (day<1 || day>30){printf_s("day error!\n");}else{reckon();}}else{if (i=1){if (day<1 || day>29){printf_s("day error!\n");}else{reckon();}}else{if (day<1 || day>28){printf_s("day error!\n");}else{reckon();}}}}}//主函数int main(){int choose=1;while (choose){printf_s("请输入一个日期（在2010.1.1以后的日期）并以英文逗号隔开：\n");scanf_s("%d,%d,%d", &year, &month, &day);if (judge()){if (j_m()){j_d();}}printf_s("继续请输入1，结束请输入0：\n");scanf_s("%d",&choose);}return 0;}
