C++ 当I'；我正在使用流对象和管道输出写入同一个文件？

这是代码：

#include<iostream>
#include<fstream>
using namespace std;

int main(){
   ofstream out("file.txt");
   //cout<<"I'm being written on console and piped to file."<<endl;
   out<<"I'm directly being written on file using ofstream object"<<endl;
   cout<<"I'm being written on console and piped to file."<<endl;
}

在档案里，猜猜我发现了什么

I'm being written on console and piped to file.
m object

请有人解释一下。。。

提前谢谢

如果您成功地打开了同一个文件两次，那么两个流都从文件的开头开始写入，我并不感到惊讶。C++规范中没有任何东西可以说它应该与shell同步输出。你期待什么？

I'm being written on console and piped to file.
m object
