関数型プログラミングについて2016/3時点での私の知識をまとめ、C++にどうやって適応していくと皆幸せになれるかを説明しました。 間違っているところなど、コメントお待ちしています。

1. Functional Programming

C++
y = cos x/3

2. Functional?
Differences from
Imperative
in C++
Agenda

3. Functional?

4. declarative code
higher-order function
static binding
lazy evaluation
Functional Programming is

5. C/C++ (Imperative)
Declarative code

6. std::function(), ,
, callback ,
DI, etc.
Higher-order function

7. Static binding

8. (eager evaluation)
C/C++
Lazy evaluation

9. PROS!

10. IO
CONS"

28. lambda

31. API
vector<int> function_name([xxx,] vector<int> &array);
result = filter_prime(sort(take3(array)));
vector<int> function_name([xxx,] vector<int> &array);
result = take3(filter_prime(sort(array)));

32. OK
Program is …
disposable
code
long life
