i need help whit my code

[Beginner007]

i am confused, i would appreciate any help and thanks in advanced.

the code is suppose register the number of 20 seat and the name of the person

in this program if you press 1 it should reserve the seat

if you press 2 it should not reserve the seat

you press 3 it should report if you reserved or not

if you press 4 it should exit the program

this part of the code is suppose to gather information if the seat is reserved or not reserved. i need to add this part to my main code.

int main()
{
	double slot[2][20];
	
	for(int i = 0; i < 20; i++)
	{
		cout << "the seat number" << (i + 1) << "?";
		cin >> slot[0][i];
		cout << "what is the name?";
		cin >> slot[1][i];
	}


	for(int i = 1; i < 20; i++)
	{
		double inf = seatReservation(slot[0][i-1], slot[0][i]);

		cout << "the staus of the table" << slot[1][i-1] << " is " << inf << endl;
	}

	
	system("PAUSE");
	return 0;
}


double seatReservation()
{
	// print if reserved or not
}

this is my main code

#include <iostream>
#include <string>

using namespace std;

int main ()
{

    bool reservationStatus[20];
	string names[20];
    int seatNumber = 1;
    int menuChoice;
    

    while (true)
    {
        cout << "Please enter a selection" << endl;

        
        cout << "Press 1 Reserve a seat" << endl;
        cout << "Press 1 Clear Reservation" << endl;
        cout << "Press 1 Order a Report" << endl;
        cout << "Press 1 Exit Program" << endl;
        cin >> menuChoice;

        switch (menuChoice)
        {
            case 1:
        for(int i=0; i < 20; i++)
        {
            reservationStatus[i] = false;
        }
        if (reservationStatus[seatNumber] == true)
        {
            cout << "not reserved" << endl;
            cin >> reservationStatus[seatNumber];
        }

                break;

            case 2:
           if (reservationStatus[seatNumber] == false)
        {
            cout << "reserved" << endl;
            cin >> reservationStatus[seatNumber];
        }
                break;

            case 3:
                // Code for the Report
                break;

            case 4:
                
                return 0;
        }
    }
	system ("PAUSE");
    return 0;
}
