... (you can see them in the first diagram), one for B and one for C who virtually inherit A. D's object size is increased because it stores 2 pointers now; however there is only one A now. So B::A and C::A are the same and so there can be no ambiguous calls from D. If you don't use virtual inheri...

... When writing programs it is extremely common to want to logically group together a set of values which do not have sufficient commonality to justify making a class. Many programming languages allow you to logically group together a set of otherwise unrelated values without creating ...

...A heuristic is still a kind of an algorithm, but one that will not explore all possible states of the problem, or will begin by exploring the most likely ones. Typical examples are from games. When writing a chess game program you could imagine trying every possible move at some depth level and app...
