ASCII中的数字10"是换行字符\n.在C ++中，这是换行符.

The "number 10" in ASCII is the line feed character, \n. In C++, this is the newline character.

您显然已将文件作为文本流打开.因为换行符在不同平台上的表示方式不同，所以文本流执行换行符翻译:在读取时，它们将平台特定的换行符表示转换为\n；在编写时，它们将\n字符转换为平台特定的换行符表示.

You have apparently opened the file as a text stream. Because newlines are represented differently on different platforms, text streams perform newline translation: when reading they translate the platform-specific newline representation into \n and when writing they translate the \n character into the platform-specific newline representation.

在Windows上，换行符由\r\n表示.当您向文本流中写入\n时，它将被写入为\r\n.

On Windows, line breaks are represented by \r\n. When you write a \n to the text stream, it gets written as \r\n.

要写入原始二进制数据，需要将流作为二进制流打开.这是通过将ios_base::binary标志传递到流的构造函数来完成的.

To write raw binary data, you need to open the stream as a binary stream. This is done by passing the ios_base::binary flag to the constructor of the stream.
