Hi i am trying to pass a whole file into a string. This is my Code but the program is always exiting on the first if(). I just can't get behind what i am doing wrong here.

```
#include <iostream>
#include <fstream>
#include <string>

std::string readFile (std::string filename);

int main() {
    std::string filename;
    std::string Eingabestring;

    std::cout << "Geben Sie eine Datei an" << std::endl;
    std::cin >> filename;
    Eingabestring = readFile(filename);

    std::cout << Eingabestring << std::endl;

    return 0;
}

std::string readFile (std::string filename)
{
    std::string zeile,inhalt ;
    std::ifstream quelle;
    quelle.open(filename.c_str());

    if (!quelle)
    {
        std::cerr << filename << " kann nicht geöffnet werden!\n";
        return exit(-1);
    }

    while (!quelle.eof())
    {
        getline(quelle,zeile);
        inhalt = inhalt + zeile;
    }

    return inhalt;

}

```

Already thanks for your help!

Edit: I just noticed that i put the file into a wrong folder.. But the code still isn't reading the whole file. Just the first line, but i thought with the loop i could get every line of my file into the string?

And i fixed the second return 0 to exit(-1). Thats better right?
