以下程序运行后的输出结果是 【18】 。
#include ＜stdio.h＞
main()
int i,m=0,n=0,k=0;
for(i=9;i＜=11;i++)
switch(i/10)
case 0: m++;n++;break;
case 10: n++;break;
default: k++;n++;
printf("%d%d%d\n",m,n,k);
参考答案：1 3 2
解析： 在程序中，i从9开始循环，当i=9时，执行case 0后的语句m++；n++；此时m =1，n=1，然后执行break，跳出循环；当i=10时，执行detault后的语句k++；n++；此时k=1， n=2；当i=11时，再执行default后的语句，k=2，n=3。此时，m=1，n=3，k=2。输出结果为 1 3 2。
