競プロ 環境構築

一応現時点で使っているものをメモしておく。

• C++14 を想定
• VSCode で C/C++ (ms-vscode.cpptools) と C++ Intellisense (austin.code-gnu-global) という拡張を入れる
• VSCode の settings.json に以下を加える（これは不要？）

    "C_Cpp.updateChannel": "Insiders",
    "C_Cpp.default.compilerPath": "/usr/bin/g++",
    "C_Cpp.default.cppStandard": "c++14",
    "C_Cpp.default.intelliSenseMode": "gcc-x64",
    "C_Cpp.default.includePath": ["/usr/local/include"],
    "clang.cxxflags": [
        "-std=c++14"
    ],
