In C++, when a method is declared, I’ve noticed that sometime the method may have an assignement appended to it.
Could anyone tell me what this is?
For example:
virtual void MyMethod () = 0;
What doe the ‘= 0’ mean. 🙂
Thanks everyone !!!
It means it’s a pure virtual function, i.e. no actual definition of it is available in this class and it must be overridden in a subclass. It’s not actually an assignment as such, zero is the only value you can “assign”.
And this is C++ syntax; in C# the same would be accomplished with the
abstractkeyword.
