算法：使用基姆拉尔森计算公式
#include "stdio.h" #include <stdlib.h> void CaculateWeekDay(int y,int m, int d) { if(m==1||m==2) { m+=12; y--; } //使用基姆拉尔森计算公式 int iWeek=(d+2*m+3*(m+1)/5+y+y/4-y/100+y/400)%7; switch(iWeek) { case 0: printf("星期一\n"); break; case 1: printf("星期二\n"); break; case 2: printf("星期三\n"); break; case 3: printf("星期四\n"); break; case 4: printf("星期五\n"); break; case 5: printf("星期六\n"); break; case 6: printf("星期日\n"); break; } } int _tmain(int argc, _TCHAR* argv[]) { int year=0,month=0,day=0; printf("请输入日期：\n格式为：1900,1,1\n"); char temp = '1'; while (temp != '0') { scanf("%d,%d,%d",&year,&month,&day); scanf("%c",&temp); CaculateWeekDay(year,month,day); printf("输入0退出,其他继续:"); scanf("%c",&temp); } system("pause"); return 0; }欢迎童鞋们访问并收藏我的博客小程序：
