在这一步,我们需要将二进制数据写入到文件中。 # 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...
cout << "Now writing the data to the file.\n"; file.write(reinterpret_cast<char *>(buffer), sizeof(buffer)); file.close (); // Open the file and use a binary read to read contents of the file into an array file.open("nums.dat", ios::in); if (!file) { cout << "Error ...
fgetc 是 file get char 的缩写,意思是从指定的文件中读取一个字符。fgetc() 的用法为: intfgetc(FILE *fp); fp 为文件指针。fgetc() 读取成功时返回读取到的字符,读取到文件末尾或读取失败时返回EOF。 EOF 是 end of file 的缩写,表示文件末尾,是在 stdio.h 中定义的宏,它的值是一个负数,往往是 -1。

cstruct maps bytes (i.e. binary data) to MATLAB structures and vice versa. It is very useful for unpacking binary data from a disk file, or preparing MATLAB data for sending over an interface. The name 'cstruct' is derived from its original use of reading binary data from a socket ...
