[Help] Menu making function!

[Xel]

#include <iostream>
#include <stdlib.h>
#include <windows.h>


char draw_menu(char title[50], char op1[50], char op2[50], char op3[50], char op4[50])
{
cout << "[" << title << "]\n\n";
cout << "1. " << op1 << endl;
cout << "2. " << op2 << endl;
cout << "3. " << op3 << endl;
cout << "4. " << op4 << endl;
}


int main()
{
draw_menu("Main Menu", "Start game", "High Scores", "Help/About", "Exit");

Sleep(10000);
}

I want to be able to add more than 4 options to draw_menu,
but I don't want to make it look like this

char draw_menu(char title[50], char op1[50], char op2[50], char op3[50], char op4[50], char op5[50], char op6[50], char op7[50], char op8[50])

What can I do?


ANOTHER QUESTION! Is it ok to do this

game()
{
....
menu(); //getting back to menu so it won't exit right away
}

menu()
{
...
game();
}


int main()
{
menu();
}

Can I just call menu() to get back to it or should I do a while() and return a value?

I take it this is for some kind of handheld PvP script? If so.. Very nice.
If you can wait a little bit, I could get my friend to check it out for you and see what the problem is.. if somebody doesn't reply within 8hrs at least.

C++ variable arguments in functions

[Xel]

I did not understand that website jjaa gave.

To clarify a bit I just need a function which can be given as many words as you want
without declaring like 100 variables or so.

The program should create a new variable each time a new word is given for function
draw_menu();

[jjaa]

#include <stdio.h>
#include <stdarg.h>
#include <iostream>

using namespace std;

void draw_menu(char* title, ...)
{

    //Declare a va_list macro and initialize it with va_start
    va_list l_Arg;
    va_start(l_Arg,title);

    cout << "[" << title << "]\n\n";

    char* val  = va_arg(l_Arg,char*);
    int i = 0;

    while (val != NULL)
    {
        
        cout << ++i <<". " << val << endl;
        val = va_arg(l_Arg,char*);
        
    }
    va_end(l_Arg);
}

int main()
{
    draw_menu("Main Menu", "Start game", "Bored", "Yay");
    draw_menu("Main Menu", "Start game", "Bored", "Yay", "Again", "bored");
    draw_menu("Main Menu");
    return 0;
}

I haven't used C++ for a long time. But, that should give you the basic idea.

That's how you'd do it in C.

Doing it like that in C++ is REALLY bad. (Google it if you don't believe me, but it should be obvious why)

Until variadic templates are added to the language (and all the mainstream compilers), your options are:
* Pass in a container (e.g vector<string>)
* Use operator overloading and chaining (See Boost.Format for an example)
* Use function overloading (though you'd probably want to use the preprocessor for this, and that in itself comes with a lot of issues and pitfalls)
* Probably something else I've forgotten
