complier error

[menewbie]

Hi guys!

I am working on a small project which contains three files
1. MainTest.cpp
2. CashRegister.h
3. CashRegister.cpp

I have done everything that suppose to be done but still I am getting an error and can not execute the program.... can anyone points out what is wrong with my program?

Here is the code

// MainTest.cpp

#include <iomanip>
	using std::setw;
	using std::left;
#include <iostream>
	using std::cout;
	using std::endl;
	using std::ios;
#include "CashRegister.h"

const char ERROR[] = "Error! Registration failed."; 

int main()
{
	CashRegister cash("Register.txt", 5);

	cout << "This test should give five error messages below!" << endl;
	cout << "------------------------------------------------" << endl;

}

//CashRegister.cpp

	~CashRegister(); // registered items and balances

	bool registerItem(int category, char* articleName, double amount);
	double batchTotal(){
		double total = _batchTotal;
		_batchTotal = 0;	// batchTotal() is expected to reset _batchTotal;
		return total;
	}
private:
	ofstream _file; // Here will registered items be saved
	int _nrOfCategories; // products are organized in categories
	double* _categorySums; // The vector will contain respective sum of each category sold during the day
	double _batchTotal; // sold since the last summation
};

// CashRegister.h
#ifndef CASHREGISTER_H
#define CASHREGISTER_H

	CashRegister(char* fileName, int nrOfCategories);
	bool registerItem(int category, char* articleName, double amount);
    double batchTotal();

#endif 

any kind of help will be appreciated... thanks in advance

What error? is it compile time or runtime? What error message is?

[menewbie]

Hi guys!

Thanks for your time and reply. I have made the changes you have suggested and moved the class declaration and definition to .h file

and now the error I am getting is error: 'ofstream' does not name a type

the line it is point out is:
ofstream _file;

[MiiNiPaa]

1) You could forgot to #include <fstream>
2) You might want to use qualified name std::ofstream

[menewbie]

the error I am getting is

undefined reference to 'CashRegister::CashRegister(char*, int)'
undefined reference to 'CashRegister::registerItem(int, char*, double)'

[MiiNiPaa]

Your .h file does not contain class declaration. It only have freestanding functions.

[menewbie]

so how to fix it? do i need to write class declaration in the .cpp file? or in the headerfile?

[MiiNiPaa]

Class declaration in header file.
Definition of class functions in cpp file.
Include .h file where needed
Make sure that cpp file is compiled and linked.
