Question

I want to read then store the content of a file in an array, but this isn’t working:

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main () {
    string content,line,fname;
    cout<<"Execute: ";
    cin>>fname;
    cin.ignore();
    cout<<endl;
    //Doesn't work:
    ifstream myfile(fname);
    if(!myfile.is_open()){
        cout<<"Unable to open file"<<endl; 
    }else{
        while(!myfile.eof()){
            getline(myfile,line);
            //I don't know how to insert the line in the string
        }
        myfile.close();
    }
    cin.get();

    return 0;
}

2 things.
When creating your ifstream, you must pass a char*, but you’re passing a string. To fix this, write :

ifstream myfile(fname.c_str());

Also, to add the line to the content, call the “append” method :

content.append(line);

It works for me 🙂

If you actually want to store each line seperatly, store every line into a string vector, like Skurmedel said.
