There must be thousands and thousands of examples for creating and reading from a text file in C++ out there. Have you done any research at all into your problem (whatever it actually is)?

Of course he has!
He found here, didn't he? :laugh:

I wonder if you google "do my homework for me" if the first hit is CP....

But a simple mod to the search string found this on the fourth try...:sigh:

It's "no" btw. CP isn't even on the first page.

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
So is the MFC, CLR, Linux, or what?
What have you tried? Where are you stuck? What do you want to read and write from the file?

C++

// reading a text file
#include < iostream > 
#include < fstream >
#include <string >
using namespace std;
 
int main () {
string line;
ifstream myfile ("example.txt");
if (myfile.is_open())
{
while ( getline (myfile,line) )
{
cout << line << '\n';
}
myfile.close();
}
 
else cout << "Unable to open file"; 
 
return 0;
}

Reading from a file can also be performed in the same way that we did with cin:

// reading a text file
#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main () {
string line;
ifstream myfile ("example.txt");
if (myfile.is_open())
{
while ( getline (myfile,line) )
{
cout << line << '\n';
}
myfile.close();
}

else cout << "Unable to open file";

return 0;
}
