ofstream将无符号的短写到文件 [英] ofstream write unsigned short to file

问题描述

#include "stdafx.h"
#include <iostream>
#include <fstream>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
std::ofstream fout("..\\INVNTRY.dat"); // output, normal file
unsigned short nianq = 2570;
fout.write ((const char*)&nianq,sizeof(nianq));
fout.close ();
return 0;
}

文件长度为4，但不是2.为什么?
我使用vs.net 2005

the file longth is 4,but not 2.why?
i use vs.net 2005

推荐答案

更改为std :: ofstream fout(".. \\ INVENTRY.dat"，ios_base :: binary);

ofstream默认情况下是基于字符的.运行时将插入回车符/换行符.

Change to std::ofstream fout("..\\INVENTRY.dat", ios_base::binary);

ofstream is character-based by default. The runtime inserts a carriage return/line feed.
