Reading/Writing txt files

I'm writing a program that accepts a file and inputs each line from a txt file into a vector. Is it correct to use:

Code:

class filereader
{
public:
filereader(string filename);
private:

}
filereader::filereader(string filename)
{
   vector<string> v;
   ifstream File(filename.c_str());
   cin.getline(filename.c_str());
   v.push_back(filename);
   while(cin.good())
   {
      cin.getline(filename.c_str());
      v.push_back(filename);
   }
}

The class is not what I'm using, it's just to complement the function. What I need help with is the function filereader(string filename).

I'm sort of confused. I would appreciate any help!

> cin.getline(filename.c_str());
> v.push_back(filename);
c_str() is a CONST, so you shouldn't be trying to modify it with getline.

Something like

Code:

   vector<string> v;
   ifstream File(filename.c_str());
   string line;
   while ( File.getline( line ) ) {
      v.push_back(line);
   }

Is there an overloaded function in streams that read into a std::string? I don't think so, IIRC.
You may have to use std::getline(yourfile, yourstring);
