Question

Hello, I am working on a project for my C++ class, I have the vast majority of the code figured out but am running into a few issues. Mainly updating each * to an X. The problem is as follows:(Airplane Seating Assignment) Write a program that can be used to assign seats for a commercial airplane. The airplane has 13 rows, with six seats in each row. Rows 1 and 2 are first class, rows 3 through 7 are business class, and rows 8 through 13 are economy class. Your program must prompt the user to enter the following information: a. Ticket type (first class, business class, or economy class) b. Desired seat Output the seating plan in the following form: A B C D E F Row 1 * * X * X X Row 2 * X * X * X Row 3 * * X X * X Row 4 X * X * X X Row 5 * X * X * * Row 6 * X * * * X Row 7 X * * * X X Row 8 * X * X X * Row 9 X * X X * X Row 10 * X * X X X Row 11 * * X * X * Row 12 * * X X * X Row 13 * * * * X * Here, * indicates that the seat is available; X indicates that the seat is occupied. Make this a menu-driven program; show the user’s choices and allow the user to make the appropriate choices.

and my code is as follows:

#include <cstring>
#include <iomanip>
#include <iostream>

void displayPlane(char[][6], int, int);
void fillArray(char[][6]);
using namespace std;
int main(int argc, char **argv) {
char airplaneSeats[13][6];
fillArray(airplaneSeats);
int priceTotal = 0;

char seatType;

cout << "This program will help you choose your seat on an airplane." << endl;
cout << "First class is the first two rows, business is the third to seventh "
"row, and economy is the eigth to thirteenth row."
<< endl;

bool seatTypeValid = false;
while (!seatTypeValid) {
cout << "Do you want to sit in (F)irst class, (B)usiness, or (E)conomy?: ";

cin >> seatType;
if (seatType == 'F' || seatType == 'B' || seatType == 'E') {
seatTypeValid = true;
} else {
cout << "Please enter a valid seat type!" << endl;
}
}
switch (seatType) {
case 'F':
displayPlane(airplaneSeats, 0, 1);
break;
case 'B':
displayPlane(airplaneSeats, 2, 6);
break;
default:
displayPlane(airplaneSeats, 7, 12);
}

bool seatAvailable = false;

int rowNum;
char letter;
int convertedLetter;
  
while (!seatAvailable) {
bool correctRow = false;
while (!correctRow) {
cout << "Enter the row number of your chosen seat: ";
cin >> rowNum;
if (seatType == 'F' && (rowNum > 0 && rowNum <= 2)) {
correctRow = true;
} else if (seatType == 'B' && (rowNum > 2 && row <= 7)) {
correctRow = true;
} else if (seatType == 'E' && (rowNum > 7 && rowNum <= 13)) {
correctRow = true;
} else {
cout << "You entered an invalid number, please enter a number in your "
"chosen class!"
<< endl;
}
}
cout << "Please pick a seat from A-F." << endl;
cin >> letter;
convertedLetter = (int)(letter)-65;
if (airplaneSeats[(rowNum - 1)][convertedLetter] == 'X') {
cout << "That seat is taken, please choose another seat!" << endl;
} else {
seatAvailable = true;
}
}

airplaneSeats[(rowNum - 1)][convertedLetter] = 'X';

return 0;
}
}
void fillArray(char airplaneSeats1[][6]) {
for (int r = 0; r < 13; r++) {
for (int c = 0; c < 6; c++) {
airplaneSeats1[r][c] = '*';
}
}
}
void displayPlane(char airplaneSeats2[][6], int i, int h) {
cout << left << " A B C D E F" << endl;
string rowNums[13] = {"Row 1", "Row 2", "Row 3", "Row 4", "Row 5",
"Row 6", "Row 7", "Row 8", "Row 9", "Row 10",
"Row 11", "Row 12", "Row 13"};
for (int r = i; r <= h; r++) {
cout << setw(6) << rowNums[r] << " ";
for (int c = 0; c < 6; c++) {
cout << airplaneSeats2[r][c] << " ";
}
cout << endl;
}
cout << endl;
}

any help would be greatly appreciated!

//Your program worked fine, except one error which i have corrected. This program runs only once, so seat assignment takes place just once. Please tell how this program is to be structured if you want it to behave differently
