Following C++ Array questions.

[lilzz]

1) ClassA &* tempA;
I guess that's a pointer to a reference. Why do you need a pointer to a reference? isn't a reference almost like a pointer itself.

2) ClassB<templA, templB>Ar (3, 4, 1)
what does it means <templA, templB> ? I have seen one template parameter inside but not two. What's (3, 4, 1)? Array initialization? An array of 3 initialized to 3, 4, 1?

3)[*ilx](index)
what's this ? dereference of ilx and then [ ] and a parameter of index?

lilzz,

You have a lot of these little C/C++ puzzles for us. Without any particular project/purpose in mind. You know, there are many books on the language that contain the answers.

Please be so kind as to acknowledge the comments to your last puzzle before we move on to this next batch.

I wonder if we're being used as Lilzz's online homework answer generator. Perhaps we should all give the wrong answers so that she fails with a D- grade.

1. Reference to a pointer?
2. Template can have as many parameters as you want. The parameters will depend on the template/class definition.
3. A pointer to a function which is called with the parameter index

As others have said, you have posted a lot of c++ etc questions recently, none of which appear to be Pi related. Please consider using a C++ forum for these types of questions, or searching up front with Google.

Are 1) and 2) trick questions? I can't see how they will even compile.
