Read File

[commencer]

No error, but it does not read file

My class include string acno2, name_st, date2 and address_st; and I want to add new student:

  account ac;
	fstream outFile;
	outFile.open("Student.txt", ios::app | ios::out | ios::in);
	string dismiss;
	string acno;
	if (!outFile)
	{
		cout << "File could not be open !! Press any Key...";
	}
    else
    {
        ac.student_creac();
        while (!outFile.eof())
        {
            getline(outFile,acno,',');
            if (getline(outFile,dismiss,'\n'))
                if (ac.acno2==acno)
                {
                cout << "\tAccount existed, please enter another account." << endl;
                outFile.close();
                add_st();
                }
        }
    }
    outFile << ac.acno2 << ',' << ac.name_st << ',' << ac.date2 << ',' << '"' << ac.address_st << '"' << '\n';
    cout << "added" << endl;
	outFile.close();

Where is your text file? Where is your executable file? Where is your project file, if any?

If you're using an IDE, sometimes the default working directory is where the project file is, and not in the /bin folder. Try moving your file around.

Also, if on windows, you can try
system("cd"); to see where your program is executing from.

On Linux/Mac, do system("pwd");

my text file and executable file inside project file (where program is executing), i use this code to show (and even modify), and the same file it work properly but to add new data from the above code it is not work

account Lst;
    string dismiss;
	ifstream inFile2;
	inFile2.open("Student.txt", ios::in);
	if(!inFile2)
	{
		cout << "File could not be open !! Press any Key...";
	}
    while (inFile2)
    {
        getline(inFile2,Lst.acno2,',');
        getline(inFile2,Lst.name_st,',');
        getline(inFile2,Lst.date2,',');
        getline(inFile2,dismiss,'"');
        getline(inFile2,Lst.address_st,'"');
        if (!inFile2)
        {
            break;
        }
        Lst.report2();
    }
    inFile2.close();

Thanks

So it does open the file correctly, but fails at some point when reading.

I'm not sure then, try running your code through a debugger line-by-line so that you can tell where it starts to fail.
