Have you ever had an embarrassing(尴尬的)experience? Last week we asked readers to tell us about embarrassing experiences.  We received thousands of letters! Here is a selection.

Tony:

My most embarrassing experience happened when I had just left university. I had just started teaching in a Liverpool secondary school. One morning my alarm clock didn't ring. I woke up at half past eight and school began at nine. I quickly washed, dressed, jumped into my car and rushed to school. When I arrived, the students had already gone into class. I didn't go to the office, but went straight into class. After two or three minutes the students began laughing, and I couldn't understand why! Suddenly I looked down and understood. I had put on one black shoe and one brown shoe!

Henry:

The most embarrassing experience I've ever had, happened two years ago. After seeing a film, my wife and I had lunch in our favourite restaurant in town. Then we decided to take a walk along the street. The street was very busy and we started holding hands. Suddenly my wife saw a dress that she liked in a shop window, and stopped. I started looking at some watches in the next window. After a minute or two I reached for my wife's hand. There was a loud scream, and a woman slapped my face. I hadn't taken my wife's hand. I'd taken the hand of a complete stranger!

James:

My wife and I had decided to buy a new house, and I'd made an appointment to see our bank manager. I'd never met him before. I went into town in my car and I was lucky enough to find a parking space outside the bank. I'd just started reversing(倒车) into the space when another car made its way into it. I was irritated! I opened my window and shouted at the man in the car. He ignored me and walked away. It took me twenty minutes to find another place. As soon as I had parked the car, I rushed back to the bank. I was ten minutes late for my appointment. I went to the manager's office, knocked and walked in. The manager was sitting behind his desk. He was the man who had taken my parking space!

下列给定程序中,函数fun的功能是:先把形参a所指数组中的最小值放在元素a[0]中,把a所指数组中的最大值放在a[1]元素中;再把a所指数组元素中的次小值放在a[2]中,把a所指数组元素中的次大值放在a[3],依次类推。
例如,若a所指数组中的数据最初排列为:9,1,4,2,3,6,5,8,7;则按规则移动后,数据排列为:1,9,2,8,3,7,4,6,5。形参n中存放a所指数组中数据的个数。
规定fun函数中的max存放当前所找的最大值,px存放当前所找最大值的下标。
请在下划线处填入正确的内容并将下划线删除,使程序得出正确的结果。
注意:部分源程序给出如下。
不得增行或删行,也不得更改程序的结构!
试题程序:
#include<stdio.h>
#define N 9
void fun(int a[],int n)

int i,j,max,min,px,pn,t;
for(i=0;i<n-1;i+=2)

/********found********/
max=min= (1) ;
px=pn=i;
for(j=i+1;j<n;j++)
/********found********/
if(max< (2) )
(max=a[j];px=j;)
/********found********/
if(min> (3) )
(min=a[j];pn=j;)

if(pn!=i)
(t=a[i]=a[i]=min;a[pn]=t;
if(px=i)px=pn;
if(px!=i+1)
(f=a[i+1];a[i+1]=max;
a[px]=t;)


void main()

int b[N]=(9,1,4,2,3,6,5,8,7),i;
printf("\nThe original data:\n");
for(i=0;i<N;i++)
printf("%4d",b[i]);
printf("\n");
fun(b,N);
printf("\nThe data after moving:\n");
for(i=0;i<N;i++)
printf("%4d",b[i]);
printf("\n");
