iostream ifstream 转化

Question

例如

	ofstream fout;

	cout = fout;

	cout << "123";

这些其实就输出到文件了

类似这样的能实现吗？

Answer 1

您的意思是手动输入文件名，然后打开该文件读写数据吗？

类似下面这样的：
#include <iostream>
#include <fstream>
using namespace std;
....
char szPath[MAX_PATH] = {0};
cin >> szPath;
ifstream in(szPath, ifstream::xxx);
if(in)
{
 ....
 in.close();
}

Answer 2

我的意思是测试的时候用cout，等测试完用cout=ofstream这样一句就把cout定向到文件，抱歉啊，没说清楚

Answer 3

请使用std::freopen。大概使用方法：

#ifndef _DEBUG
std::freopen(R"(C:\test.txt)","w+",stdout);
#endif
