#include <stdio.h> int main() { /* 定义需要计算的日期 */ int year = 2008; int month = 8; int day = 8; int sum, flag; switch (month) { case 1: sum = 0;break; case 2: sum = 31;break; case 3: sum = 59;break; case 4: sum = 90;break; case 5: sum = 120;break; case 6: sum = 151;break; case 7: sum = 181;break; case 8: sum = 212;break; case 9: sum = 243;break; case 10: sum = 273;break; case 11: sum = 304;break; case 12: sum = 334;break; } sum = sum + day; if (year % 400 == 0) flag = 1; else flag = 0; if (flag == 1 && month > 2) sum++; printf("%d年%d月%d日是该年的第%d天", year, month, day, sum); return 0; }
闰年条件表达式那里有问题,建议改成:(year%400==0||(year%4==0&&year%100!=0))
闰年的条件是:
①能被4整除且不能被100整除;
②能被400整除;
闰年是4的倍数且不是100的倍数,可以改成(year / 4 == 0|| year % 100 != 0)
