First C++ Program Getting Errors

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!

You're getting it because you didn't declare the variables... — tpg2114, Feb 06 '12 at 18:11
Not that it has anything to do with your error messages, but `system("pause");` always gives me -- er, pause. See http://stackoverflow.com/q/1107705/10077 — Fred Larson, Feb 06 '12 at 18:18

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;

The constants need types too. – Ben Voigt Feb 06 '12 at 18:14
Doesn't VC++ add unsigned int if it sees a variable declaration like "auto i" or "const i". It's only printing out errors for the "Total" variables. – dreta Feb 06 '12 at 18:33
it does, but thats not to say you should let it! – StevieG Feb 06 '12 at 18:57

Understanding compiler errors is something you'll soon learn, as you practise!

const isn't a type, it's a modifier. orchestraPrice should be declared:

const int orchestraPrice = 25;

You have three similar lines with the same problem.

And you haven't declared orchestraTotal before you use it. Try this instead:

const int orchestraTotal = orchestraNum * orchestraPrice;

Again, you have three similar lines with the same problem.

I recommend reading a book or two on C++. See The Definitive C++ Book Guide and List .

Good luck!

Thanks I will take a look at the book. Right now we are reading in my intro class An Introduction to Programming with c++ by D.Zak – Feb 06 '12 at 18:19

You need to declare variables before you use or while you initialize them.

int orchestraTotal = orchestraNum * orchestraPrice;
int mainTotal = mainNum * mainPrice;
int balconyTotal = balconyNum * balconyPrice;
int overallTotal = mainTotal + balconyTotal + orchestraTotal;

you have not declared the 4 variables:

mainTotal, bacolnyTotal, orchestraTotal, overallTotal

The other common cause of this error is spelling and capitalization mismatches, which your answer has in spades. – Ben Voigt Feb 06 '12 at 18:18

orchestraTotal = orchestraNum * orchestraPrice;
mainTotal = mainNum * mainPrice;
balconyTotal = balconyNum * balconyPrice;
overallTotal = mainTotal + balconyTotal + orchestraTotal;

Turn these into definitions and you should be fine. You don't declare or define any of these variables before using them, that's why the compiler is printing errors.
