Is there a good algorithms book with examples written in modern C++ (that's using all the recent additions to C++)?
>>53349211
interested too

> C++11
But you don't need move semantics, variadic templates, and smart pointers to implement BSTs, heaps, sorts, and tree traversals.
It kinda sounds like you're new to C++ and algorithms in general. For learning algorithms, you really shouldn't have to worry about the language syntax details.
Btw, and implemention of these things in!C++ will mostly look like it would in C.
>>53349684
there are things you can do using new C++ to speed up algorithms
>>53350087
assembly and c destroys anything in speed
>>53350122
in the real world the speed of writing the code also counts
and I'm not so sure C is reliably faster anymore

Step 1: learn the concept of programming
Step 2: learn the math of algorithms and running times
Step 3: look at pseudocode for proven algorithms
Congratulations you can now write algorithms for any language. If you can't, then programming may not be for you.

It does, but most if not all won't apply to what you're thinking about.
Care to prove me wrong?
Compile time computations via constexpr functions (not as useful until C++14) aren't really going to apply here if we're talking runtime sorts, tree/graph traversals, etc.

= you can't write anything in any real world language
Fuck C++, what about Rust ?
most algorithm books are written using java for examples, but i've always thought basic C was better suited for learning them.
i guess the Skiena book uses C and I've heard good things about it.
There's a version of Sedgewick using C++, btw, OP.
>>53350122
SBCL is faster than C.

Learn the algorithms and then just implement them using the new features
I used this book for my algorithms course I really liked it. All the examples in here are in java but unless you're new to programming you should be able to implement them in any language you want
there isn't really a lot of java specific stuff in this book
>>53351347
>most algorithm books are written using java
Only the really shitty ones.
>>53350087
No, the new stuff in C++11/14 really just make things faster to code.
>>53349684
>using smart pointers
kek, fucking casual
>>53349211
If you understand the algorithms, you shouldn't need/want more than pseudocode. Only retards demand copy-pastable source code

The other choices are a psychopath that has a history of deceit and evil, and a commie who's so dumb he thinks calling himself an honorary woman will help him gain female voters over an actual woman.
>>53353855
The difference is that I'm pretty sure she's a pro and unlike spoiled brat psychopath will more or less respect the boundaries as politicians learn. Her husband was a pretty good president, even worked a lot with the other side and got a lot of shit done.
>>53353722
bullshit, there are some tricks you can do now that also speed shit up
3 years ago I knew exactly what they were :)
the algorithms which use Java basically use it like C
If it was C++14 it would be a shitshow
I have that OP book, it is really nice

The best books on algorithms use pseudocode to convey implementations.
Searching high and low to find the one book using a specific version of a specific language is just doing yourself a disservice; it is sure to be subpar in comparison to the best learning resources out there on this subject (all of which use pseudocode and don't clutter things up with language specific details).
Besides, do you really want to end up like all the other C++ fizzbuzzers in this thread that have no idea what they're talking about? Learn C++ properly and separately from algorithms using the proper resources, and then, if you must, figure out the best way to translate that algorithm pseudocode into C++ yourself.
Btw, this smells like
