    Doesn't Compile

    Hey guys, my family is starting a sort of in house bank and i want to write a program for it that will manage the accounts. I have started it a little bit and its not compileing. Its not much now but here is the source and the compiler log.

    Code:
    #include <iostream>
    #include <fstream>
    #include "stdafx.h"
    
    using namespace std;
    
    class Banker
    {
    public:
    	
    	const int CHECKING = 1;
    	const int SAVINGS = 0;
    
    
    	Banker(string name, int sBalance);
    	 ~Banker();
    	int GetBalance(int account);
    	int Deposit(int amount, int account);
    	int Transfer(int amount, Banker recieve);
    protected:
    	int balance;
    	string name;
    
    };
    
    int main()
    {
    	cout<< "Welcome to the Cullen Familly Banking Program.\n";
    	cout<< "Please select a choice:\n";
    	cout<< "1. Deposit";
    	cout<< "2. Check Balance";
    	cout<< "3. Make a transfer";
    	return 0;
    }

    What is your compiler? These errors are very strange to me.

    The only thing I see you must fix is the CHECKING and SAVINGS initialization. You must do it at the constructor.

    Set your project to not use precompiled headers and remove the stdafx.h include directive.

    MSC silently ignores everything that comes before the PCH include directive. Thus, it simply ignores your including iostream and fstream, thus has no definition of the std namespace and consequently doesn't let you use it.

    Make CHECKINGS and SAVINGS static and leave the initializations where they are.

    But static members must be initialized outside the class, donīt they?
    Code:
    class C{
       static int number;
    };
    
    int C::number = 1;
    And why make it static? Does every object will have the same value for these variables?

    Code:
    class C{
       static int number;
    };
    
    int C::number = 1;
    That's for variables. For constants, it's different. In modern compilers, they can get their values inside the class. (They still need a definition outside, though.)
    Code:
    class C{
       static const int number = 1;
    };
    
    const int C::number;

    And why make it static? Does every object will have the same value for these variables?
    Given that he wanted to initialize them in the class, I'd say yes. They're constants, not variables.

    How do you set it to not use precompiled headers? And what is MSC and PCH?

    Heres new code:

    Code:
    // Bank Program.cpp : Defines the entry point for the console application.
    //
    #include <iostream>
    #include <fstream>
    
    using namespace std;
    
    class Banker
    {
    public:
    	
    	static const int CHECKING;
    	static const int SAVINGS;
    
    
    	Banker(string name, int sBalance);
    	 ~Banker();
    	int GetBalance(int account);
    	int Deposit(int amount, int account);
    	int Transfer(int amount, Banker recieve);
    protected:
    	int balance;
    	string name;
    
    };
    
    int main()
    {
    	cout<< "Welcome to the Cullen Familly Banking Program.\n";
    	cout<< "Please select a choice:\n";
    	cout<< "1. Deposit";
    	cout<< "2. Check Balance";
    	cout<< "3. Make a transfer";
    	return 0;
    }
    Now ive only got this error about precompiled headers...

    c:\cpp stuff\bank program\bank program\bank program.cpp(36) : fatal error C1010: unexpected end of file while looking for precompiled header directive
    Error executing cl.exe.

    Bank Program.exe - 1 error(s), 0 warning(s)

    Thanks CornedBee!

    Justin C, your code compiles right in gcc 3.2. Maybe a new line after the end of main()?

    Somewhere in the project options, there's a point called "precompiled headers". You need to set it to "Don't use precompiled headers."

    MSC stands for Microsoft C compiler, PCH for precompiled header.

    In the future, check the "Empty Project" box when creating a new project.

    The first might be because you didn't include <string>. The second probably as well.
