Optimisation

Hi every one!

I've wrote this (see code below), and i have some questions:

* is this code safe and even useful?
* how can i rewrite this code so that i just need to log one time as root and not have to check password each time i use a command?

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



using namespace std;



int main() {

    int choice;


    cout << "*******************\n";
    cout << "|    LAMP MENU    |\n";
    cout << "*******************\n\n";
    cout << "1. Start Apache\n";
    cout << "2. Start Mysql\n";
    cout << "3. Stop Apache\n";
    cout << "4. Stop Mysql\n";
    cout << "5. Reload Apache\n";
    cout << "6. Reload Mysql\n";
    cout << "7. Quitter\n\n"; // "Quitter" is "Exit" in french
    cout << "Choix: ";

    cin >> choice;

    if (choice == 1) {

        system("su -lc 'service httpd start'");
        cout << "\n\n";

    }
    else if (choice == 2) {

        system("su -lc 'service mysqld start'");
        cout << "\n\n";

    }
    else if (choice == 3) {

        system("su -lc 'service httpd stop'");
        cout << "\n\n";

    }
    else if (choice == 4) {

        system("su -lc 'service mysqld stop'");
        cout << "\n\n";

    }

    else if (choice == 5) {

        system("su -lc 'service httpd reload'");
        cout << "\n\n";

    }
    else if (choice == 6) {

        system("su -lc 'service mysqld reload'");
        cout << "\n\n";

    }
    else if (choice == 7) {

        exit(0);

    }
    else {

        cout << "\n\nChoisis entre 1 et 7...\n\n";

    }

    main();


}
