read/write to the same file (getting gmon.out)
My homework asks that I use a single file to output data to, send calculations to that file, and read the results from that file. The data is a series of input ages from 1-100, controlled by a decrement counter based off of a variable cin by user: totalAges.
The problem I'm having is that the file is not being created as variable.txt it is gmon.out.
i've looked at a bunch of tutorials tried to troubleshoot myself, tried to use fstream/ofstream/ifstream etc... I can't figure it out. How can I get it to first write the data to a file, then read FROM that file?
The error i'm mostly getting is:
data>>age;
No match for 'operator>>'.
AND

^^ that happens a bunch which i'm thinking is trying to use ofstream with ios::in.
I'm not sure how to accomplish this task.
#include <iostream>
#include <iomanip>
#include <cmath>
#include <cstring>
#include <fstream>
using namespace std;
int totalAges;
int age;
string str_fileIn;
int average = 0;
cout<<"Enter a filename.\n";
cin>>str_fileIn;
ofstream data;
data.open //this may be the problem but i'm not sure why exactly.
((str_fileIn+".txt").c_str(), ios::in | ios::out);
counter = totalAges;
for (counter; counter>=1; --counter)
{
cout<<"Enter an age value 1-100. ";
cin>>age;
average = average + age;
}
average = average /totalAges;
highest = age;
lowest = age;
while(data.is_open())
{
if (age > highest)
{highest = age;}
if (age < lowest)
{lowest = age;}
data>>age; //this operator will not work here!
counter++;
if (counter==totalAges)
data.close();
}
Sorry If i missed something crucial I tried to include as much info as possible while not being a textbook.
Thank you.

When you do
data>>age;
you are trying to read from the output stream. You should be using << to write instead:
data<<age;
Before that though, you need to check if the file actually is open, or any writing to it will not work. You also need to make sure the file is created where you think it is created. It might not where you expect it to be, so search for it.

The gmon.out file is the output from the gprof runtime profiling tool. You must have enabled gprof profiling in your compilation settings. It has nothing to do with your output file.
Your output file is being created, if it gets created at all, in the directory where your executable gets executed from. Which is not necessarily the same directory with your source files are, or the directory where the executable gets created. Check your compiler settings to determine which directory your executable runs from, and you should find your variable.txt file there.
