User integer and character Validation

[AfroManCompsci]

Okay so now every time I run my program i try to check to see if i enter the same seat twice it displays the message but doesn't count it towards the overall sales and also when i key in seat 1a it still takes it as though i already inputted the seat character as well here is my code

      #include<iostream>
#include<string>
#include <iomanip>
using namespace std;

#include "C:\Users\barta\OneDrive\Documents\Visual Studio 2015\Projects\Project 4\Project 4\array.h"

void displayPlane(char msg[], char[ROW][COL]);
void getData(int &, char &);
void salesReport(int classCtr[], double fare[], string classes[]);

int main()
{
    int row = 0;
    int total = 0;
    char seat;


    while (row != -1)
    {

        displayPlane("\tChesapeaake Airlines", layout);
        cout << endl;
        getData(row, seat);
        if (row == -1)
            break;
        cout << endl;
        int COL = seat - 'A';
        if (layout[row - 1][COL] == 'X')
        {

            cout << "Sorry this seat is taken" << endl;
        }
        else
        {

            layout[row - 1][COL] = 'X';
            std::cout << std::fixed;
            std::cout << std::setprecision(2);

            for (int i = 0; i < 3; i++)
            {
                total += classCtr[i];
            }
        }

    }
    double percentOccupied;


    cout << setw(18) << "Total Seats =  " << total << endl << endl;
    percentOccupied = ((double)total / 36) * 100;
    cout << setw(22) << "Percent Occupied = " << percentOccupied << endl;
    cout << endl;
    salesReport(classCtr, fare, classes);
    cout << endl << endl;

    cout << "Have a nice day! " << endl;

    system("pause");
    return 0;
}
void displayPlane(char msg[], char[ROW][COL])
{
    cout << msg << endl;
    for (int r = 0; r < ROW; r++)
    {
        cout << endl;
        cout << setw(4) << r + 1;
        for (int c = 0; c < COL; c++)
        {
            cout << setw(4) << layout[r][c];
        }

    }

}
void getData(int& row, char& seat)
{
    cout << "Enter row <-1 to stop>  ";
    cin >> row;
    cout << endl;
    if (row == -1)
        return;
    if (row == 1)
    {
        classCtr[0]++;
    }
    else if (row >= 2 && row <= 4)
    {
        classCtr[1]++;
    }
    else if (row >= 5 && row <= 9)
    {
        classCtr[2]++;
    }

    cout << "Enter your prefered seat  ";
    cin >> seat;
    seat = toupper(seat);


}
void salesReport(int classCtr[], double fare[], string classes[])
{
    double totalSales = 0;
    for (int i = 0; i < 3; i++)
    {
        totalSales += classCtr[i] * fare[i];
    }
    cout << setw(34) << "Sales Report\n\n" << setw(23) << "Ticket Price" << setw(16) << "Total Sales\n\n"
        << setw(14) << classes[0] << "\t" << fare[0] << setw(6) << classCtr[0] << setw(9) << fare[0] * classCtr[0] << "\n\n"
        << classes[1] << "\t" << fare[1] << setw(6) << classCtr[1] << setw(9) << fare[1] * classCtr[1] << "\n\n"

        << "\t\n\n Total Sales = " << totalSales;
}

here is the header file
[/code]
/arrays for airline problem

const int ROW = 9;
const int COL = 4;
const int CTR = 3;

//initial seats in the plane
char layout[ROW][COL] = { { 'A', 'B', 'C', 'D' },
{ 'A', 'B', 'C', 'D' },
{ 'A', 'B', 'C', 'D' },
{ 'A', 'B', 'C', 'D' },
{ 'A', 'B', 'C', 'D' },
{ 'A', 'B', 'C', 'D' },
{ 'A', 'B', 'C', 'D' },
{ 'A', 'B', 'C', 'D' },
{ 'A', 'B', 'C', 'D' }};

int classCtr[CTR] = {0,0,0};

string classes[] = {"First Class", "Business Class", "Coach"};

double fare [] = {500, 300, 100};

Hello,

you call getData to receive the row. Then you change classCtr in that function. After the function returns you check whether the seat is already taken.
The next time a valid seat is entered you sum up these "invalid" changes.
