C++ press enter to continue - c++

Question

Evening, I am looking for a way to get the program to continue on instead of exiting out after asking to press enter to continue. 1 I cannot use the list command because im calling function "seatingChart" in another function and having the list command sends me back into the menu. Any suggestions?
void seatingChart()
{
for(row = 0; SEATROWS > row; ++row) // Placeholder for '#'
for (seat = 0; SEATS > seat; ++seat) // Placeholder for '#'
theater[row][seat] = '#'; // Applying '#' to the chart
cout << "\n\t\tSeats";
cout << "\n 123456789012345678901234567890" << endl; //seat header
for (int row = 0; SEATROWS > row; ++row)
{ // Initializing 15 rows
cout << "\nRow " << setw(2) << row+1 << "\t";
for (int seat = 0; SEATS > seat; ++seat)
{ // Initializing 30 seats
cout << theater [row][seat];} //display seating chart
}
cout << "\n\n\n\tLegend:\t* = Sold";
cout << "\n\t\t# = Available";
cout << "\n\n\nPress the Enter key to continue.";
cin.ignore();
cin.get();
}
}
Entire code below: I get the issue when I input "1" at the menu in order to display the seating chart.
#include <iostream>
#include <iomanip>
using namespace std;

double price[ROWS][COLS];
const int SEATROWS = 15; //PAT
const int SEATS = 30;//PAT
char theater[SEATROWS][SEATS];//PAT
int row;//PAT
int seat;//PAT
const char TAKEN = '*';//seats taken
const char EMPTY = '#';//seats free
int main()
{
int x; // Loop counter
for (x=0; x<ROWS;x++)
{
cout << "Please enter ticket price for Row " << setw(2) << (x + 1) << ": ";
cin >> price[x][COLS];
}
list();
return 0;

Answer 1

Unless you wrap your entire menu code inside a loop and make the exit condition for this loop the user input(in your case typing 5 for exit) the program will terminate as soon as it returns from your seatingchart() function because the list() function will return to main(i.e seatingchart() returns to list() and list() will return to main() ). You should do something like this:
do
{
cout << "\n\n\n\t\tC++ Theatre" << endl << endl;
cout << "\n\t1. View Available Seats";
cout << "\n\t2. View Seating Prices";
cout << "\n\t3. View Ticket Sales";
cout << "\n\t4. Purchase a Ticket";
cout << "\n\t5. Exit the Program\n\n";
cout << "\n\tEnter your choice(1-5): ";
cin>>choice;
while(choice>5 || choice<1)
{
cout<<"Choice must be between 1 and 5. Please re-enter:";
cin>>choice;
}
if (choice == 1)
seatingChart();
else if (choice == 2)
getPrices();
else if (choice == 3)
viewSales();
else if (choice == 4)
ticketSales();
else if (choice==5)//this is your exit condition
break;//will break out of the menu loop
}while(1);//the is your menu loop
By the way there are some logical errors in your code, see the comment that are given in the comment section and correct them.
