A cin function for files?

[18hRX9L8]

Hello, I have this piece of code here, which opens a text file and puts text in it.

     std::ofstream myfile;
     myfile.open(filename);
     myfile << text << endl;

I was wondering if there is a >> operator to get lines from the text file.
For example:

     std::ofstream myfile;
     myfile.open(filename);
     myfile >> text >> endl;

Yep, there is: the std::ifstream class (with >> operator): http://www.cplusplus.com/reference/fstream/ifstream/ and
http://www.cplusplus.com/doc/tutorial/files/

Thanks Fransje.

Just a few other questions, how do you know when you are at the end of the file?
For example:

while(!FALSE)
{
     myfile >> text;
     if (text==NULL)
     {break;}
}

Also, would I define text as string? Does >> take the full line or the full file or a char?

Thanks!

Generally you would structure your while loop like so:

while ( myfile >> text )
{
    // process
}

// we're done with myfile.
