三个数输出最大值 int a, b, c,t; scanf_s("%d%d%d", &a, &b, &c); if (a < b) { t= a; a = b; b = t; } if (b < c) { t = b; b = c; c = t; } if (a < b) { t = a; a = b; b = t; } printf("%d %d %d\n",a,b,c); 用switch语句实现循环
第一类型
int main()
{ int day = 0; scanf_s("%d", &day); switch (day) { case 1: printf("星期一\n"); break; case 2: printf("星期二\n"); break; case 3: printf("星期三\n"); break; case 4: printf("星期四\n"); break; case 5: printf("星期五\n"); break; } 第二类型 switch (day) { case 1: case 2: case 3: case 4: case 5: printf("weekdays\n"); break; case 6: case 7: printf("weekends\n"); break; }
