inData outData

[golkab]

I am trying to understand how to save to a file and how to access the file and display to the screen as my cout<<, can someone do a step by step for me so I can practice this?? This is what I started but stuck now:
#include <iostream>
#include <string>
#include <iomanip>
#include <fstream>


using namespace std;

main ()
{

//declare variables
ifstream inData;
ofstream outData;
string numString;

//open data file
inData.open("Prog5_1.txt");
outData.open("Prog5_1.txt");

//prompt the user
cout<< "Enter a series of numbers, example: 123456: " << endl;
cin >> numString;
inData >> numString;

if (inData.is_open())
{
while (inData.good())
{

cout << numString << endl;


}

}

return 0;
}
