You could use class ifstream.

It makes very easy to read from a file as an input stream.

If you are not required to use the C++ library, then use the C one. I always preferred the C one. Even in my college courses, where we were expected to use C++ I was not penalized for using the standard C library. If you are going to school, you might want to double check if this is acceptable. IMO the C++ standard library using too confusing and abstracted of a syntax to be understandable. Plus I knew how to look at standard C code on paper and determine what the result would be, in C++ I wasn't and still can't always do this.
