Question

Ok so for an assignment we have to make our first program. Mine is to make a program that calculates the ticket revenue for each seating section at a theater. The problem is that I keep getting this undeclared identifier or identifier undefined error along with like 23 other errors. The program I am using is Visual Studio 2010 Premium.

Here is my code.

// Chp4HWprgm.cpp 
// Created by Bryce Easley on 2/6/2012
#include <iostream>
using namespace std;

int main(){
//declare variables

int orchestraNum = 0;
int mainNum = 0;
int balconyNum =0;
const orchestraPrice = 25;
const mainPrice = 30;
const balconyPrice = 15;

//enter input of sales
cout << "Number of Orchestra tickets sold?";
cin >> orchestraNum;
cout << "Number of Main Floor tickets sold?";
cin >> mainNum;
cout << "Number of Balcony tickets sold?";
cin >> balconyNum;

//calculate revenue for each and total revenue
orchestraTotal = orchestraNum * orchestraPrice;
mainTotal = mainNum * mainPrice;
balconyTotal = balconyNum * balconyPrice;
overallTotal = mainTotal + balconyTotal + orchestraTotal;

//display figures
cout <<"Orchestra Revenue: $" << orchestraTotal << endl;
cout <<"Main Floor Revenue: $" << mainTotal << endl;
cout <<"Balcony Revenue: $" << balconyTotal << endl;
cout <<"Overall Revenue: $" << overallTotal << endl;

system("pause");
return 0;}
//end of main function 

Here are my errors:

Gracias to everyone that answered. I seriously stared at this forever and I couldnt figure it out. It’s like learning a whole new language and it’s a bit confusing!

Answer 1

You need to declare your constants and total variables with types:

const int orchestraPrice = 25; 
const int mainPrice = 30; 
const int balconyPrice = 15;

...

//calculate revenue for each and total revenue 
int orchestraTotal = orchestraNum * orchestraPrice; 
int mainTotal = mainNum * mainPrice; 
int balconyTotal = balconyNum * balconyPrice; 
int overallTotal = mainTotal + balconyTotal + orchestraTotal;
