When to define a virtual destructor
Hello people,
I know that in a base class you should define the destructor as virtual but is there any cases that you define a destructor as virtual. In the case when you implement assignment operator and copy constructor you need to implement the destructor as well but does it need to be virtual too or not?
many thanks -

How to format decimal numbers
Hi guyz,
could anyone please tell me how can I convert an integer variable like 1 to a string variable but with this format 00X where x is the number, I mean like let's say I want to have a string with fixed size (let's say 3) and I want to convert an int variable into that string but if the int variable is less than 100 I want it to have 0s before that so 1 -> 001 and 10->010

well I use Windows XP and VS2005 and I don't have any problem about compiling or linking my application, all I want is a tool which automatically reviews the code based on some rules and shows me for instance if I have any unused variable or anything like that...Leave a comment:

Virtual Destructor
Hi everyone,
I have a class hierarchy with A as the base class, then I have another class B which inherits from A and another class C which inherits from B. so A<--B<--C. I have a method "Read" define in all three classes, but it's only virtual in A and B and not C. I only define A's destructor as virtual but now B and C. My question is should I define B's destructor as virtual too or not.
