Preprocessor issues

I am having severe issues with preprocessor commands.

I have 3 files

• account.h
• account.cpp
• bank.cpp

bank.cpp makes use of account as a class.
I just end up with a ton of errors every time I compile (they seem like they could fill a post on their own)

Here is account.h

Code:

#ifndef _Account_
#define Account

class Account
{
  double money;                      // amount of money held by this account
  double interestRate;  // a monthly or yearly interestrate, depending on how the account is to be used.


public:

     // create an account with an initial amountand a specified interest rate

	Account(double amount, double percent);


     // return the account's balance
  double balance();
     // add money to the account
  void deposit(double);
     // substract money from the account
  void withdraw(double);
     // add money according to the interest rate.
  void addInterest();

};
#endif

Here is account.cpp

Code:

#include "account.h"



		     // create an account with an initial amountand a specified interest rate
		  Account(double amount, double percent)
		  {
			money = amount;
			interestRate = percent;
		  }

			 // return the account's balance
		  double balance()
		  {
			return money;
		  }

			 // add money to the account
		  void deposit(double amount)
		  {
			money += amount;
		  }

			 // substract money from the account
		  void withdraw(double amount)
		  {
			money -= amount;
		  }

			 // add money according to the interest rate.
		  void addInterest()
		  {
			money *= (1 + interestRate/100.0);
				  // this, ofcourse, is the same as money = money * (1 + (interestRate/100) );
		  }

And here is bank.cpp

Code:

#include <iostream>
#include "account.cpp"

using namespace std;


	void main(void)
	{
		Account stdAccount(100, 4); // create an account with £100and 4% interest rate

	  stdAccount.addInterest();
	  cout << "Balance: " << stdAccount.balance()<< endl;

	  stdAccount.deposit(50);
	  cout << "Balance: " << stdAccount.balance()<< endl;

	  stdAccount.withdraw(100);
	  cout << "Balance: " << stdAccount.balance()<< endl;

	  int i;
	  cin >> i;
	}

Any help with this issue would be really appreciated!

The errors that appear to begin with are
Error 1 error C2062: type 'double' unexpected d:\users\tom\documents\visual studio 2008\projects\bank\bank\account.h 14
Error 3 error C2062: type 'double' unexpected d:\users\tom\documents\visual studio 2008\projects\bank\bank\account.cpp 6
Error 11 error C2062: type 'double' unexpected d:\users\tom\documents\visual studio 2008\projects\bank\bank\account.h 14
Error 13 error C2062: type 'double' unexpected d:\users\tom\documents\visual studio 2008\projects\bank\bank\account.cpp 6

Thanks for reading my post

You never include .cpp files.

thanks for pointing out that tab I feel like a right fool now! but learning is like that

ok after modifying the top of my bank.cpp to look like this

Code:

#include <iostream>
#include "account.h"

using namespace std;
using namespace account;

it cuts the error count down to 23 and dumps these 4 out to start

#include <iostream>
#include "account.h"

using namespace std;
using namespace account;

Thanks

There's also a problem here:

Code:

#ifndef _Account_
#define Account

You should define the same macro that isn't defined. And you shouldn't use identifiers beginning with underscore(s) (the precise rules are bit more complicated), since these are reserved for compiler / standard library implementations.

And you shouldn't declare macros that collide with other names you want to use (macro Account and class Account). A popular way to ensure that macros don't collide with other identifiers is to use all caps for them. And for header guards you might also use a suffix like *_H or *_DEFINED.

I fixed it by simply adjusting my preprocessor commands in account.h and adding private: before my variables

see new account.h top

Code:

#ifndef Account_h
#define Account_h

class Account
{
private:
  double money;                      // amount of money held by this account
  double interestRate;  // a monthly or yearly interestrate, depending on how the account is to be used.


public:

     // create an account with an initial amountand a specified interest rate
  Account(double amount, double percent);

Thanks for all the help
