The C++ Standard Library: clang++とg++でコンパイルしてみた(まとめ)
https://qiita.com/kaizen_nagoya/items/9bdfaa392443d13e5759

#目的(purpose)
The C++ Standard Libraryコンパイル記録は、コンパイラおよび対応標準、コンパイラの版により、コンパイルエラーMessageの違いを記録し、どのエラーが出たら、どの版またはどの対応標準にすればエラーが少なくなるかを考察するための資料の第一歩です。

#成果(outcome)
(1)コンパイラの種類、対応標準の違いによってエラーの数が違う。
(2)同じエラーであってもMessageの表現が違う。
(3) Error Messageのネットで検索する際に役立つ。

#編纂器(compiler)

clang++

clang version 6.0.0 (tags/RELEASE_600/final)
Target: x86_64-apple-darwin17.5.0
Thread model: posix
InstalledDir: /usr/local/opt/llvm/bin

g++

complex2でclang++は入力待ちになる。どちらも
12, 34, 56, 77と入力すると次のようになる。

$./a.out
12
complex number c1: complex number c2: 34
c1 raised to the c2: (4.92224e+36,0)

45
