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...

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...

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. ...

FILE 定义在 stdio.h 中。有兴趣的读者可以自己去找一下 FILE 的定义。 我们给出 FILE 的一般定义: typedef struct { char *fpos; /* Current position of file pointer (absolute address) */ void *base; /* Pointer to the base of the file */ unsigned short handle; /* File handle */ short...
# 写入二进制数据到文件binary_data=b'\x48\x65\x6c\x6c\x6f'file.write(binary_data) 1. 2. 3. b'\x48\x65\x6c\x6c\x6f'是一个包含Hello的二进制数据。 write()方法用于将二进制数据写入到文件对象中。 步骤3:关闭文件对象 在这一步,我们需要关闭文件对象,确保数据已被写入并保存。
