How do I read text files?

Hi I already found a tutorial on this but it didnt work. But I am wondering if anyone can tell me how to read text files line by line and determine what they say. Also is it posibble to make a new enumerated type but have it also be a function or class? Or would that cause errors?
Thanks ahead for helping.

How to read a textfile

very easy to do in QT ( a well developed C++ framework)

Code:

---

QFile myfile("text.txt");
myfile.open(QFile::ReadOnly);
QTextStream myreader(&myfile);
QString  linereader = myreader.readline(); // reading one line at a time
Qstring  readall = myreader.readall() // read all texty into a single QString  same as std::string

if you are new to C++ then stick with well established framework as QT or wxwidgets

these frameworks make writing C++ code relatively easy and offer tons of easy to use API
further they are very well documented.

I'd say qt is much better documented than wx. I'd also say for reading files stl is simple enough :)

I just realised this might be in the wrong section but I use visual C++ for compiling c++ and it makes errors for the way I tried to do it. So how would I do it with that? It has an error where I
type:

ifstream myfile;

the error is "ifstream is unidentified"
So how would I do this on visual c++
