Your poor indentation has blinded you to the obvious

while (getline(in_File, line)) {
    // snipped
    in_File.close();
}

You close the file after just one line!

> while (!out_File.eof())
Since you don't touch out_File inside this loop, I have to wonder what your plan is here.

Thanks Salem. I would like to search the file by account number and get the whole of this... but when I tried to search it only get the first line. Would you be able to help me on that please. Thanks

<< stu.student_number << endl
<< stu.first_name << endl
<< stu.middle_name << endl
<< stu.last_name << endl
<< stu.strGender1 << endl
<< stu.age << endl
<< stu.birth << endl
<< stu.address << endl
<< stu.strCN1 << endl
<< stu.stremail_add1 << endl
<< stu.father_name << endl
<< stu.mother_name << endl
<< stu.strProgram << endl;

Are you trying to copy all the records from "Student.txt" to "Temp.txt", where this is true
> if(key == stu.student_number)
kimikimy (3)
yes, salem.. after copying into the file ("Student.txt" to "Temp.txt") it will search the inputted student number (Key) and if it is the same with the stu.student_number.. it will output in C++ with all the given categories...

Thanks!!

Well searching through Temp.txt is going to be a right royal PITA because the information you want to filter out is spread out over many lines.

Filtering while you read will be so much easier

cout << "Enter SN ";
cin>> key;
while (getline(in_File, line)) {
    parseLine(line,stu);  // yes, make that mass of lines a separate function.
    if(key == stu.student_number) {
        out_File << "=====" << endl << endl
                 << stu.student_number << endl
    }
}




What's going on here?

		strGender << stu.gender;
		strGender >> stu.strGender1;
		getline(ss, stu.strGender1, ',');

You haven't read anything into stu.gender yet.
