在Linux中编译的程序;t检测'n'在Windows运行时所在的fstream中换行

编辑：

在我的代码的某些部分中，我在fstream上使用peek()函数来查看打开的.txt文件中的下一个字符是否是换行符，我认为它在我的.txt文件中定义为字符n。在Windows中编译和运行时，我的程序会正常运行，并将打开的文件中的每个换行符解释为n。但是，当我在Linux中运行用g++编译的同一程序时，当当前位置位于文件中的一行末尾时（不正确），我的if (file.peek() != 'n')语句返回true，Windows在该行返回了与false相同的语句（正确）。为什么会这样在Linux和Windows中打开的.txt文件中，新行是由n以外的字符定义的吗

代码段：

if (counter % 5 == 0){
    cout << "counter % 5 = " << counter % 5 << endl;
    cout << "counter = " << counter << ". " << "true: (counter % 5 == 0)" << endl;
    if (counter < 125){
        cout << "counter = " << counter << ". " << "true: (counter < 25)" << endl;
        if (file.peek() != 'n'){
            cout << "counter = " << counter << ". " << "returned false on (file.peek() != '\n')" << endl;
            return false;
        }
    }
}

终端输出（g++）：

counter % 5 = 0
counter = 5. true: (counter % 5 == 0)
counter = 5. true: (counter < 25)
counter = 5. returned false on (file.peek() != 'n')

这是我试图以字符串形式复制的.txt文件：

test.txt：
