You should format your error message. Most likely those are compling errors.

Try to correct those errors, please look at line e.g string(line position) string(395). If you need help, copy the error line with code and post them here.

Try this;
1) Change every 'cout' to 'cin' where it appears in getline().
2) initialize i=0 on line 3.
3) Change every 'member' to 'Data[i]'.
4) Eliminate the 3rd parameter Details &member.

member doesn't belong in your SaveData(). Did you miss one? It should be gone completely.

OK. Try fixing the first problem and lets see how the error messages change.
i is an undeclared indentifier because the for loop begins and ends on line 3 (due to the extra ; on that line).

also these are now merging for some reason?

so when I go to input it comes out like this

agE IS fine because I did cin >> age;

The function has replaced it, but I wouldn't stay with that myself.
The DataEntry() function is where the "magic" of writing a Details object to a file occurs. You could call it from your SaveData() function (which would make your SaveData() function have very little code), but you would have to change a couple of things. You can't open and close the file everytime DataEntry() is called. Passing an ofstream object (to the open output file) should work.
You would open and close the file in SaveData().

Option B is you just leave SaveData() as is. It will do the job fine.

I didn't understand the merging problem. Could you explain it again please?
