Reading the unsigned char from the file using << operator

原文 2019-01-06 16:33:50 8 1 c++/ file

I should read unsigned char from file and I don't know is it a char or a number. I can use the " << " operator only.

So if unsigned char in a file is a char I have no problems, but if it is a number it does not read it into a variable .

Data in files does not have types. There are no "chars" or "unsigned chars" or "numbers".

A file contains bytes . Period.

It is down to you to decide how to interpret those bytes.

Typically we have a convention or "file format" to help us decide how to do that for some given file.
