以下程序的输出结果是______。
main( )
int y=9;
for(;y＞0;y--)
if(y%3==0)
printf("%d",--y);continue;

答案

参考答案：852

解析：循环前，变量y的值为9，其中，循环语句在y大于。情况下循环，每次循环后y的值都减1。循环体是当y能被3整除时输出表达式--y，输出的是减1后的y值。这样，第一次循环因y为9，能被3整除，输出8，y也变成8。又经两次循环，y的值变为6，又让y减1变成5，并输出5；又经两次循环，y的值变成3，让y减1变成2，输出2；再经两次循环后，y的值变成0，结束循环，所以程序输出852。

The young boy and his father sat quietly watching the snow fall on a snowy Saturday afternoon.
“Dad, my friend told me that every snowflake is 36   . But they look all the same to me. How can we tell?” the child asked.

“Choice,”Dad said. "Their choices 42 them what they are.”
“ 43 choice is a bad thing?” the boy asked.
“Oh, no. Only when we choose the 44 things.”
“How do we tell right from wrong?" the child asked.
Dad was given the chance to build upon the foundation of his son's 45 . He reached down and began to 46 with the snow. He 47 the snow into two sides, three large snowballs on one side and several smaller ones on the other.
“Which side did the right thing?” he asked the boy.
The child looked at both sides but 48   answer. Then Dad placed the three larger snowballs on top of each other.
“It’ s a snowman! The side 49 made me snowman!” the boy replied with 50
Yes, all these people came together and recognized how special each of them was, so they joined in a(n) 51   to build up mankind,” Dad said.
The child then stood up and 52 an arm full of the smaller snowballs. One by one he began to throw them at the other small piles of snow. He said,”This is what happens when people can't work together. They have a(n) 53 .”
Dad was shocked. He stood up, lifted the boy and 54 him tightly, whispering to him, “I hope that your world will learn to work and live together. I hope you will make the right   55
