reading in binary file 1

[yaids]

Hello,
I want to open a binary file and read in a single octet of data (I assume this to be one-byte?). Is there a C++ function that does this?

Yes, of course.

#include <iostream>
#include <fstream>
using namespace std;

ifstream f("thefile.xxx",ios::binary);
char ch;
if (f.get(ch))
{
   ...
}

Or use old good C library streams from <cstdio>:

#include <cstdio>
FILE* f;
char  ch;
f = fopen("thefile.xxx","rb);
if (f && (ch=fgetc(f)) != EOF)
{
   ...
}

What's a problem? It's basic C/C++ i/o mechanics...
