Can you help me on this project of mine?
Here's the problem.

It's a payroll system where the employee can enter his/her record. After entering his/her record it will be stored in a file. If their might be changes the employee might want to change he/she can be able to edit the record. Since it is a payroll system their will be many employees, so you must be able to add other records.

To sum it all up the main objective is to:
Make a payroll system, where you can enter, edit, display, and add a record.

Please help me out on this.

heres the code i made
but then some parts work i only have a problem with the edit part and how i can input many records

#include<iostream.h>
#include<fstream.h>

You can start by trashing out those old iostream.h and fstream.h headers and start using the modern ones:

#include <iostream>
#include <fstream>
using namespace std;

You'll also want to edit in your code tags as i described in my previous post (assuming it's not too late to edit by the time you read this).

I don't quite get your problem. You say there's a problem entering multiple records. What exactly do you mean by this? Post any error messages that occur, which lines cause them (if you know) and such.

The program must accept multiple records. Meaning i can input may records as long as i want. It's required. The problem with my program is it only accepts one record. Which does not fit the requirement.

Hmm... I don't see why you're having a problem. The while(1) statement will keep the whole menu system rolling until the user exits, so what exactly is stopping you?

Just tried compiling your code; it has a couple of errors:

int main()
{
    int ch;
    char Filename; // make this into an array so it can hold more than 1 char!

And here:

if(ch==3)
        {
            char edit;
            cout<<"\nEnter ID number of employee you wish to edit: ";
            cout<<"\t\t:";
            cin>>Filename;
            ifstream ifile(Filename);
            // you never declared 'obj'; perhaps you meant 'object'?
            ifile.seekg(((sizeof(obj))*(Filename-1)),ios::beg);
            ifile.read((char*)&obj,sizeof(obj));
            
            obj.print();

hi,
basically if this is a school project, i guess that you need to improve your object oriented design.For example you can create a class Employee and then a class EmployeeDataBase which will have a vector containing Employee objects.This will enable you to add as many records you like, plus {i think} it is better than implementing everything in one class...{i could be wrong because i just started learning OOP:)]
