里面有各种各样的程序例子可以供初学者使用而且非常有趣欢迎刚兴趣的读者前来下载

#include<iostream.h>
#include<fstream.h>
void main()
{
	fstream file1,file2;
	char fn1[10],fn2[10],ch;
	cout<<"请输入源文件名:";
	cin>>fn1;
	cout<<"请输入目标文件名:";
	cin>>fn2;
	file1.open(fn1,ios::in);
	file2.open(fn2,ios::out);
	while((ch=file1.get())!=EOF)
	{
		cout<<ch;
		file2.put(ch);
	}
	file1.close();
	file2.close();  
}
/*第二种按行逐一复制的程序为：
#include<iostream.h>
#include<fstream.h>
void main()
{
	fstream file1,file2;
	char fn1[10],fn2[10],buf[100];
	cout<<"请输入源文件名:";
	cin>>fn1;
	cout<<"请输入目标文件名:";
	cin>>fn2;
	file1.open(fn1,ios::in);
	file2.open(fn2,ios::out);
	while(!file1.eof())
	{
		file1.getline(buf,100);
		file2<<buf;
		file2<<"\n";
	}
	file1.close();
	file2.close();
