got problems with class code

[nsmith1779]

This should be pretty simple, but I cant figure it out. I will give you all three of my files and the error code I am getting, if someone could help.

.h file

using namespace std;

class Account
{

public:
Account();
Account (double);
double getBalance();
void deposit(double);
void withdraw(double);
void addInterest(double);
private:
double balance;

};

Account.ccp file

#include<iostream>
using namespace std;
#include "Account_A.h"

Account::Account()
{
balance=0.0;
};

Account::Account(double intialBalance)
{
balance=intialBalance;
};

void Account::deposit(double depositAmount)
{
balance=balance+depositAmount;
};

void Account::withdraw(double withdrawAmount)
{
balance=balance-withdrawAmount;
};

double Account::getBalance()
{
return balance;
};

void Account::addInterest(double rate)
{
double balance=balance+balance*rate;
};

useAccount.ccp file

#include<iostream>
using namespace std;
#include "Account_A.h"
int main()
{
Account a1;
Account a2(500);
a1.deposit(200);
a2.withdraw(50);
a1.addInterest(0.2);

cout<<a1.getBalance();
cout<<"\n";
cout<<a2.getBalance();

system("pause");
return 0;
}

Here, first of all, in the function, addInterest, the local variable balance, will overshadow the class variable, balance. So the compiler thinks you are creating balance(local), and using it in the equation statement, without initialization.
Solution: change the ID(name) of one of the variables(probably the function's, since it's local).
