Moved to C++ since that is mentioned 6 times already.
I fixed the thread title as well.

I find it hard to believe that after 3 months of study, this is your first attempt at reading a file.
Your first exercise is to read the file into memory, and then print it out to the screen.
If you can't "print what you read" with any reliability, it's a waste of time working on the rest of the problem (you're just going to confuse yourself by processing garbage).
