Answer 1

Use a binary stream:

#include <fstream>

char buffer[100];
ifstream myFile ("myImage.bmp", ios::in | ios::binary);
myFile.read (buffer, 100);

myFile.close();

However, parsing it will be a bit trickier if you insist on doing it that way. I suggest you look into a generic C++ image library, such as the boost GIL (doesn’t support bmp) or this open source bmp library.

If you are unable to use any third party or OS-specific libraries, you will have to parse the data yourself. The C++ standard libraries don’t include anything to do that for you. You’ll have to start by familiarising yourself with the BMP structure. Wikipedia’s article has a good description of it.
