So virtual function overloading? Can you give a small bit of sample code to demonstrate what you mean?

Ah gotcha. Yes in the current situation we can do nearly everything that the concepts proposal for C++20 does with enable_if, void_t, and a few other helpers. Though concepts have the benefit of letting you "say what you mean", in

Concepts are also C++20. They were voted in, however, shortly after 17 shipped.

C++ doesn't have multiple dispatch. I think the OP was referring to multiple inheritance, which is not the same thing.

That's interesting, and a bit counter-intuitive IMO. But I guess that's why we measure things. The reserve operation is essentially just a single reallocation, whereas the resize is a reallocation plus a bunch of zeroing out. Stra

One other minor nitpick: know the difference between vector.resize vs vector.reserve. If all you're doing is copying new data into the vector after sizing it, use reserve. This avoids default-constructing all of the values inside of it

It doesn't make sense, in my opinion (though I could be ignorant). For classification, wouldn't it be better to stick to discrete probability mass functions?

This has been going on for a lot longer than the current US government. Chances are high it's just Zug Island, which contains blasting furnaces for steel and whatnot. The problem is that Zug Island is a part of Michigan, while Windsor

Hopefully that will be fixed in a future C++ standard. There is an interesting static reflection proposal floating around that would allow for this, plus more.

Me too. Sendmail and his friends did unspeakable things to me.

When C++11 came out, I bought the ANSI copy (identical to the ISO one except for the front page if I remember correctly) for $30. It sure beat the ISO version in terms of price.

I wrote my master's thesis in literate haskell. It was cool to watch the same source material generate either a program or a dissertation, depending on what processor I sent it through.

My supervisor's thesis from the 70's is in about as good as shape as the one linked. Must depend on when it was scanned.

xhtml: it's just a good idea, IMO.

Yep! It runs on all of my personal gear for that exact reason. Praise Bob!

The languages, idioms, and ecosystems are different enough that I don't see that as a problem. They should be treated like two different languages. You wouldn't read a C book and expect to understand the conventions of C#. Neither

Unfortunately yes. The implementation is straight forward though: template <typename Container> std::size_t size(Container const& c) { return c.size(); } template <typename T, std::size_t K> std::size_t si

Or use the std::size free function. It's overloaded to work with C-style arrays.

They've been voted into C++20! The wait may finally be over (in a few more years) :-)

It's a simple concept that appears all over in computing. I'm not surprised that that's the case.

At least in C++, knowing your type forms a monoid with your operation informs you when you are safe to use various parallel algorithms. e.g. `std::accumulate` with an associative operator is safe to run in parallel.

Nope, but they are in the pipe. Maybe we'll see them for C++20.

Access control rules are all checked at compile time. There's literally nothing to store. If you want proof, check the output of your compiler. The only thing a non-virtual struct/class might do is reorder member variables if they

Unless you explicitly type `virtual`, your C++ classes will have the exact same overhead as C structs. Even with inheritance. The memory layout of struct A { int x; }; struct B : A { int y; }; is the same as if you had written

If you have the horsepower to test a population of deep nets, then absolutely.

Genetic algorithms and the like are still useful for various combinatorial search problems. Not everything can be mapped to a smooth function, and so there will always be (in my opinion at least) room for metaheuristics.
