Cannot be overloaded?

So I'm doing a little class assignment and I've ran into a little problem. My teacher in all of his source files declares all his method signatures all at once at the top of his class. However when I tried to do that I get a compiler error. Here's the source:

#include <iostream>
using namespace std;

const short DEFAULT_TYPE = 0, CLIENT_TYPE = 1,
            EMPLOYEE_TYPE=2, ADMIN_TYPE = 3;

class Account
{
    //Public members
    public:
        bool equals(Account);
        string toString();
        void print();
        string getName();
        void setName(string);
        short getAccountType();

    protected:
        string accountName;
        short accountType;

        Account()   {
            accountType = DEFAULT_TYPE;
            accountName = "Default";
        }

        Account(short typeIn, string nameIn)    {
            accountName = nameIn;
            accountType = typeIn;
        }
        
        bool equals(Account accountIn)  {
            int equality = accountIn.getName().compare(accountName);
            return(equality == 0)? true: false;
        }

};

When I try to compile that I get this error:

I don't really know why this doesn't work. Any suggestions?

The way you are doing it is declaring two equals functions with the same argument lists. You want to write a function prototype, then implement the function definition in a .cpp file.

Account.hpp

class Account
{
//your member functions go *inside* the class declaration
public:
  //...
  bool equals(Account) const;
  //...
};

Account.cpp

//then in a seperate .cpp file you write the definitions:
#include "Account.h"
//...
bool Account::equals(Account accountIn) const
{
  return (accountIn.getName().compare(accountName) == 0);
}
//...

Ok I tried to do what was mentioned above, but I'm still having a little bit of trouble. Its a different class but the problem is the same.

Password.h

#include <string>
using namespace std;

#ifndef PASSWORD_H_INCLUDED
#define PASSWORD_H_INCLUDED

class Password  {
    private:
    string password;

    public:
    string getInput();
    bool changePassword();
    bool authenticate(string passIn);
    string toString();
    Password();
    Password(string passIn);
}

#endif // PASSWORD_H_INCLUDED

Pasword.cpp

#include <iostream>
#include <windows.h>
#include "Password.h"

using namespace std;

const string PASS_ERROR = "Incorrect Password";

bool Password::changePassword()  {
    cout << "Enter Previous Password: " << endl;
    string old = Password::getInput();
    if(Password::authenticate(old)) {
        cout << endl << "Enter New Password: ";
        Password::password = Password::getInput();
        return true;
    }
    else    {
        cout<<endl<<PASS_ERROR;
        return false;
    }
}//....

But Im still getting a compiler error heres what it says.

D:\Andy\...Password.cpp|5|error: expected unqualified-id before 'using'|

whats the problem here?

Missing semicolon on line 18 in password.h

just like the sock monster in everyones laundry room who steals socks so you only have one matching sock there is also a semicolon goblin. he steals semicolons.

ok. maybe not...
