Yeah, what Uman wrote is pretty much how you'll do it. Then all main needs is a simple loop to output all the employees in your list.

Yeah, use lists. The whole thing is actually fairly simple. I decided to do it on a whim, used a list and strings, the whole thing took about an hour of mostly copying and pasting.

You got help. Do your own homework.

Mack1982 · May 23rd, 2006, 12:08 PM

I don't want the entire code,.. Just the menu part,.. How did he do use a menu to Add and list employees,..? or perhaps a similar example would do to,...

Twilight · May 23rd, 2006, 4:05 PM

The menu was the easiest part. I just had something like the following:

(Toggle Plain Text)

std::list<Employee*> employees;

int main()
{
    string choice;
    while(1)
    {
        cout << "Decribe the options you want the user to choose from" << endl;
        cin >> choice;
        //parse choice from a string to an int

        switch(int version of choice)
        {
            case 1:  
                 //do choice1 stuff
                 system("cls");
                 break;
            case 2:
                 //do choice2 stuff
                 system("cls"); 
                 break;
            case 3:
                 //quit
                 return 0;
            default:
                 system("cls");
                 cout << "Invalid selection, ";
        }
    } 
}

This just loops forever until the user chooses your quit option. And by adding more cases, you can add more options for the user.

We were all at school/college/uni once upon a time, and we know what homework questions look like

Besides being against the rules, doing someone's homework for them is NOT doing them any favors. First, they don't learn. Secondly, in one case I'm aware of, a student was flunked entirely because his instructor happened to see the thread.

what does this error mean

(Toggle Plain Text)

First.cpp
f:\program files\microsoft visual studio 8\vc\include\sal.h(226) : error C2143: syntax error : missing ';' before 'string'
f:\program files\microsoft visual studio 8\vc\include\sal.h(226) : error C2059: syntax error : 'string'

Because I didn't use any Sal.h in my program. This thing just pops up and all the errors are in here, no in my code.

my MAIN

(Toggle Plain Text)

#include "first.h"
#include <iostream>
#include <string>

using namespace std;

int main()

Perhaps one of the include files is including another file. Looks like it. You also have another source file, First.cpp, which may have other includes in it. Information is key, both for debugging and for seeking help. Be sure and think about what you want to know and what you need to express to get there. The meaning of error messages is expanded on slightly in the help files. One should begin there. You will find that messages similar to yours are often caused by a variable (or type) not being defined. Check for matching braces, also.

One presumes that you hadn't gotten around to reading the rules. Those, the FAQ (which is the same thing, here), and posting guidelines are the first place you should turn when you begin with a forum. It gives you a sense of the community's preferences and style.
