Reading line from text file and putting the strings into a vector?

by

Simplest form:

std::string line;
std::vector<std::string> myLines;
while (std::getline(myfile, line))
{
   myLines.push_back(line);
}

No need for crazy c thingies 🙂

Edit:

#include <iostream>
#include <fstream>
#include <string>
#include <vector>

int main()

{
    std::string line;
    std::vector<std::string> DataArray;
    std::vector<std::string> QueryArray;
    std::ifstream myfile("OHenry.txt");
    std::ifstream qfile("queries.txt");

    if(!myfile) //Always test the file open.
    {
        std::cout<<"Error opening output file"<< std::endl;
        system("pause");
        return -1;
    }
    while (std::getline(myfile, line))
    {
        DataArray.push_back(line);
    }

    if(!qfile) //Always test the file open.
    {
        std::cout<<"Error opening output file"<<std::endl;
        system("pause");
        return -1;
    }

    while (std::getline(qfile, line))
    {
        QueryArray.push_back(line);
    }

    std::cout<<QueryArray[20]<<std::endl;
    std::cout<<DataArray[12]<<std::endl;
    return 0;
}

Keyword using is illegal C++! Never use it. OK? Good. Now compare what I wrote with what you wrote and try to find out the differences. If you still have questions come back.
