Answer 1

Lol wrong section - this is mathematics.... but ill help a bit anyway.
Before I start, do you know for sure the file format is in decimals?

Answer 2

and are you not worried about finding the wrong file oir anything?

Answer 3

but if I were you, I'd do something along the lines of
string name;
// get file name
ifstream ifs(name.c_str());
// do stuff (get ints out, do operations)
string oname;
ofstream ofs(oname.c_str();
// put ints in
