如何让每一行都有自己的价格。 [英] How can I make each row has it's own price.

问题描述

我只是想改变代码来自要求我输入每行的价格到不要求我输入价格但是每行都有它自己的价格这是我的代码：

I just want to change the code from asking me to enter the price for each row to not ask me to enter the price but already each row has it's own price and this is my code:

#include <iostream>
using namespace std;

int Menu ();
void Show_Seats ();
const char FULL = 'X';
const char EMPTY = '#';
const int rows = 15;
const int columns = 30;
char map [rows][columns];
double price;
int total = 0;
int seat = 450;
int seat2 = 0;
int Quit = 1;
int main ()
{
const int Num_Rows = 15;
int price [Num_Rows];
int row2, column2, cost;
int answer;

    cout << "\t*********************************************************" << endl;
    cout << "\t*                                                       *" << endl;
    cout << "\t*               Welcome to MMU Concert                  *" << endl;
    cout << "\t*                                                       *" << endl;
    cout << "\t*********************************************************" << endl;
    cout << endl << endl;
    for (int count = 0; count < rows; count++)
        {
            cout << "Please enter the price for row " << (count + 1) << ": ";
                cin >> price [count];

        }
    for (int i = 0; i < rows; i++)
        {
            for (int j = 0; j < columns; j++)
                map [i][j] = EMPTY;
        }
int choice;
    do
    {
        choice = Menu();
        switch (choice)
        {
            case 1:
                cout << "View Seat Prices\n\n";

                for (int count = 0; count < rows; count++)
                {
                    cout << "The price for row " << (count + 1) << ": ";
                    cout << price [count] << endl;
                }
                break;
            case 2:
                cout << "Purchase a Ticket\n\n";
                do
                {
                    cout << "Please select the row you would like to sit in: ";
                    cin >> row2;
                    cout << "Please select the seat you would like to sit in: ";
                    cin >> column2;
                    if (map [row2] [column2] == '*')
                        {

                    {
                        cost = price [row2] + 0;
                        total = total + cost;
                        cout << "That ticket costs: " << cost << endl;
                        cout << "Confirm Purchase? Enter (1 = YES / 2 = NO)";
                        cin >> answer;
                        seat = seat - answer;

我的尝试：



我只是想看看程序员如何做到这一点

What I have tried:

I just want to see how you programmers can do it
