constructor???
I found this code in a book.
1.)What does that line mean? Is it a constructor for 'struct's'?Code:class Binary_Search_Tree{ struct Node; Node * _root; //blah //blah }; struct Binary_Search_Tree::Node{ Type _; Node* _left; Node* _right; Node(Type = Type(), Node* =0, Node* = 0); };
I've never heard of constructors for structs.
2.)More over throughout the whole program, I dont see any
Is it correct?Code:template<class Type>
'Type' better be a typedef or class somewhere. The logical choice would've been to make it a template parameter as you suggested, but apparently, they didn't do that.
Structs can have constructors, destructors, private member data, virtual functions, inherit from one another, etc.
The only difference between classes and structs is their default access. That is:
That is the only difference.Code:struct foo1 { int bar; // This is public }; class foo2 { int bar; // This is private };
The word rap as it applies to music is the result of a peculiar phonological rule which has stripped the word of its initial voiceless velar stop.
Minor clarification: these are the only differences:Code:struct foo1 : base { // base is inherited publicly int bar; // This is public }; class foo2 : base { // base is inherited privately int bar; // This is private };
Right... Thanks.
I always explicitly state public/private inheritance, and never think about it.
Cheers

cool... I never knew this...
