Design Question mem vars
I have two very basic quesions which I hope someone could help me out with:
Say I have a class
CAccount
with member function PrintAccountName()
with private member variable m_dbAccountNumber.
Is it good practice to access the member variable directly in its own class or should I have a GetAccount() and SetAccount public member functions to access the variablei.e.
CAccount::PrintAccountNumb
{
cout<<m_dbAccountNumber;
}

What is probably the *better* way would be
LPCTSTR CAccount::GetAccountNumber
{
return m_dbAccountNumber;
}
(assuming the account number is a string)
Reason - if you wanted to check validity then it is much easier to do it in one place rather than all the places you use the account number.
Also should you need to make a change then you only need to change the code in one place - the class.

Similar code for setting the account number.

Thanks AndyAinscow,
But that doesn't really answer my question. If I access m_dbAccountNumber directly I still only need to change the code once. My question is is there a neet to use a get method?

There is no need to use functions to Get/Set the variables however there are advantages (as I said initially).
