以下程序的输出结果是______。
main()
int i，k，a[10],p[3]
k=5；
for(i=0；i＜10；i++)a[i]=i
for(i=0;i＜3；i++)p[i]=a[i*(i+1)]；
for(i=0；i＜3；i++)k+=p[i]*2；
printf("%d\n",k)；
A．20
B．21
C．22
D．23
参考答案：B
解析：[评析] 按照程序的流程走一遍，可以得到p[0]=0，p[1]=2，p[3]=6：执行三次k+=p[i]*2，相当于k=5+0*2+2*2+6*2=21。

| Last week, I visited Beijing. I always look forward to visit there.Therefore, I was so excitedly that I couldn’t fall asleep on the night before I started. I got up early and pack for the journey. In my pack, I put camera, some clothes, mobile phone and so on. It spent me 8 hours to go there by train. I visited some place of interest. They are very beautiful. I enjoyed myself. I felt tired and excited because I learned a lot of about the history of the city. As long as I arrived home, I phoned my boyfriend and told her about my journey. _______________________________________________________________________________ |
