Read it in as a BMP.  Stick any appropriate image dimension (a 1x? could work, or you could try making some factorizing algorithm).
There's extensive documentation on the BMP format (it's just a header+palette(if necessary)+image data).

IDK about a pure C/C++ implementation.  I've seen people use fseek() to the end of the file, then ftell() to get the location (ie the filesize).  I haven't programmed in C/C++ much, so I can't recommend much.
If you don't mind going into the Windows API, there's the GetFileSize function (note, if you do this, you restrict your code to only be compiled for Windows).
