#include"stdio.h" char xq[7][10]={"星期一","星期二","星期三","星期四","星期五","星期六","星期日"}; void get_result(int day){ int day_after10;//用来保存10后是星期几 day_after10=(day-1+10%7)%7;//计算10天后是星期几 printf("10天后是:%s\n",xq[day_after10]);//输出结果 } void main(){ int day; printf("今天是星期几："); scanf("%d",&day); while(day<1||day>7){ printf("必须是1至7之间的一个数,请重新输入:"); scanf("%d",&day); }//当输入的数据不满足规则时，循环输入直到满足规则为止 get_result(day); }
