1.实验名称：实验八 文件拷贝
2.实验时间：2008-6-13
3.实验目的：编程用面向对象设计思想分析、设计并实现实验八的内容。
4.实验内容：利用c++文件操作函数实现文件，将text1.txt中的内容拷贝到text2.txt中。
//源代码fcopy.cpp
#include <fstream.h>
void main()
{
char ch;
fstream text1,text2;//define inputs/outputs
text1.open("text1.txt",ios::in|ios::out);
text2.open("text2.txt",ios::in|ios::out);
while(!text1.eof())
{
text1.get(ch);
text2.put(ch);
}
text2.close();
text1.close();
}

//实验结果
//文件text1.txt中的内容如下：
abcdefghijklmnopqrstuvwxyz
//文件text2.txt中的内容如下：
abcdefghijklmnopqrstuvwxyz
5.实验总结：用面向对象的思想和方法实现文件拷贝时，把两个文件看成是文件流类的对象。判断文件结束用到了文件流类中的eof（）方法，用这种方法得到的结果多输出了一个字符。
