getch() and some more!!

[fedderico10]

I need your help please!!
I have this code (and as you can see my level in c++ programming is the worst) and i have to add two others functions to de aplication.
1. When it says "Escoja una opcion" i need it to start the action without hiting enter. Someone said it must be done with getch() but i've tried and i cant make it to work because it (c++) is very new for me and i do not know the sintaxis.
2. This program is for playing some video files so i need it to keep waiting for another instruccion after finishing one video.
Please help me! this is a work for monday and i don't really know how to do it.
Thanks!
Sorry for my bad english!

Sorry, i didn't paste de piece of code in the post above. There it goes:

#include <iostream.h>
#include <ncurses.h>
#include<stdio.h>
 
int main()
{
 
char number;
 
    cout << "Escoja una opcion\n";
    cin >> number;
 
    switch (number)
    {
        case '0':
            system("mplayer -fs '3 Doors Down - Kryptonite.mpeg'");
        break;
        case '1':
            system("mplayer -fs 'Serena Brooke surfing (fuel.tv).flv'");
        break;
        case '2':
            system("mplayer -fs 'Serena Brooke surfing (fuel.tv).flv'");
        break;
        default:
            cout << "No escogio ninguna opcion\n";
    }
}

I supose that i need to say that i'm doing it under Linux.
