这个例子利用了C++文件读写的功能,将main()函数输出到一个记事本中
#include<fstream>
#include<iostream>
using namespace std;
int main()
{
fstream fin,fout;
fin.open("main.cpp",ios::in);
if(!fin)
{
cout<<"can't open file main.cpp !";
return -1;
}
fout.open("main.txt",ios::out);
if(!fout)
{
cout<<"can't open file main.txt !";
return -1;
}
char ch;
while(fin.get(ch))
fout.put(ch);
fin.close();
fout.close();
return true;
}
