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

myfile.seekg (0, ios::beg);

{
while ( myfile.good() )
{
getline (myfile,line);
cout << line << endl;
for(int i=0; i < length; i++){
}
}
myfile.close();
}
else cout << "Unable to open file";
return 0;
}

Right now it displays the file by line.

#include <iostream>
#include <fstream>
using namespace std;
int main()
{
double left[1000], right[1000];
int lpos = 0, rpos = 0;
for(ifstream fin("integers1.txt"); fin >> left[lpos++] >> right[rpos++]; );
lpos--; rpos--;
for(int i = 0; i < lpos; cout << left[i++] << " ");
cout << endl << endl;
for(int i = 0; i < rpos; cout << right[i++] << " ");
return 0;
}
