It is said that all dreams serve a purpose（目的）. While there is no agreement among scientists about why we dream, there are many ideas about the different kinds of dreams we have.

One common kind of dream is the repeating dream, in which the same story is repeated again and again, often for many months or even years. Some believe these are a sign people have a problem in their life and once that problem is gone then the dream will stop. Others think they are a way to help people remember something very important.

Another well-known kind of dream is the nightmare. The pictures and stories in such dreams make people very afraid and dreamers usually remember them far more clearly than normal dreams. The cause of such dreams may be seeing something terrifying such as a car accident or some deadly snakes. Others think such dreams may be trying to make a person pay attention to something that is dangerous in their life.

Daydreams happen during wake-time when we forget where we are or what we are doing and find ourselves in a made-up story or unreal world. We often daydream when we are doing something that is not interesting or exciting. They help us think about our future.

Lucid dreams are the most fun. These happen when dreamers suddenly understand that they are dreaming. Instead of waking up, they stay in the dream and are able to control what happens in the dream as if they are making a movie.

结构化程序设计主要强调的是______。

A．程序的规模

B．程序的易读性

C．程序的执行效率

D．程序的可移植性

编写函数fun()，该函数的功能是从字符串中删除指定的字符，同一字母的大、小写按不同字符处理。
例如：程序执行时输入字符串为turbo c and borland c++，从键盘上输入字符n，则输出后变为turbo c ad borlad c++。
如果输入的字符在字符串中不存在，则字符串照原样输出。
注意：部分源程序已存在文件test18_2.cpp中。
请勿改动主函数脚in和其他函数中的任何内容，仅在函数fun的花括号中填入所编写的若干语句。
文件test18_2.cpp的内容如下：
#include＜stdio.h＞
#include＜iostream.h＞
#include＜conio.h＞
void fun(char s[ ], int c)


void main ( )

static char str[ ]="turbo c and borland c++";
char ch;
cout＜＜"原始字符串:\n"＜＜str＜＜end1;
cout＜＜"输入一个字符:";
cin＞＞ch;
fun(str.ch);
cout＜＜"str="＜＜str＜＜end1;
