ofstream:- no output on the text file though the file is getting created

Question

    void megaadmin()
    {
        system("cls");
        cout<<"this console is only for registering new admins";
        cout<<"please enter the required username";
        string temporary_string;
        cin>>temporary_string;
        ofstream f("admin_details.txt",ios::out|ios::app);
        f<<temporary_string;
        cout<<"please enter the password";
        cin>>temporary_string;
        f<<temporary_string;
        cout<<"would u like to enter more usernames and passwords if yes enter 1 eles 2";
        int n;
        cin>>n;
        if(n==1)
            megaadmin();
        else
            exit(0);
    }

admin_details.txt is getting created but the information that is the username and password that i entering is not getting stored in that particular text file

*When* and *how* do you check the contents of the file? Perhaps you should `flush` the buffers before checking? — Some programmer dude, Oct 02 '17 at 08:19
Also (but unrelated to your problem), I suggest you use *loops* instead of recursion in the code you show. — Some programmer dude, Oct 02 '17 at 08:19
Also unrelated: there's no point in specifying `ios::out` on an `ofstream`. — molbdnilo, Oct 02 '17 at 08:35
@Someprogrammerdude i am new to c++ how would i flush in this code? — varun krishna, Oct 02 '17 at 09:09
@varunkrishna use `ostream::flush()`. For example, `f.flush()`. — Null, Oct 02 '17 at 09:26

After each cin >> temporary_string; I would add cout << temporary_string for debugging only to make sure that the string is read successfully.

If it is, then there is no output since your stream is probably not flushed. Just call f.flush() and you should see the content.

BTW, when you close the program, the stream will be flushed as well during destruction, so you will see the content as well.
