上述代码一个使用的是text file mode,一个是binary file mode,但结果生成的二进制文件中保存的仍然是ASCII码,直接用记事本就可以打开查看。要说区别,主要是换行符的区别,binary file的换行符为<LF>,而text file的换行符为<CR><LF>,仅此而已,我就想怎么回事啊,我明明是用二进制模式打开的文件呀,怎么里面直接...
file.open("stuff.dat", ios::out | ios::binary); 1. 请注意,ios::out 和 ios::binary 标志使用|运算符联合加入到语句中,这导致文件以输出和二进制模式打开。 注意,默认情况下,文件以文本模式打开。 ostream 和 ofstream 类的 write 成员函数可用于将二进制数据写入文件或其他输出流。要调用该函数,需指定...
Now let's suppose the second binary fileoldprogram.binexists in the locationE:\cprogram. The second function opens the existing file for reading in binary mode'rb'. The reading mode only allows you to read the file, you cannot write into the file. ...

Binary files also usually have faster read and write times than text files, because a binary image of the record is stored directly from memory to disk (or vice versa). In a text file, everything has to be converted back and forth to text, and this takes time. ...
