====== Programming - Visual Studio - Configure Visual Studio ======

Within .vscode,

Add some more compiler arguments (also called flags) to tasks.json.

<code json tasks.json>
{
  "version": "2.0.0",
  "tasks": [
    {
      "type": "shell",
      "label": "C/C++: g++ build active file",
      "command": "/usr/bin/g++",
      "args": [
        "-pthread",
        "-g",
        //"${file}",
        "${workspaceFolder}/*.cpp",
        "-o",
        "${fileDirname}/${fileBasenameNoExtension}",
        "-Wall",
        "-Wextra",
        "-Wconversion",
        "-Wsign-conversion",
        "-Wshadow",
        "-Wpedantic",
        "-std=c++23"
      ],
      "options": {
        "cwd": "${workspaceFolder}"
      },
      "problemMatcher": [
        "$gcc"
      ],
      "group": {
        "kind": "build",
        "isDefault": true
      }
    }
  ]
}
</code>

<WRAP info>
**NOTE:**

  * The arguments **-Wall**, **-Wextra**, **-Wconversion**, **-Wsign-conversion**, and **-Wshadow** will instruct the compiler to warn us about many different types of common mistakes.
    * VS Code will then display these warnings right in the editor.
    * This is an incredibly useful feature, which will automatically detect and help prevent potential bugs in our code.
    * Never develop any C or C++ program without turning on all of these warning flags!

  * In addition, **-Wpedantic** and **-std=c23** will instruct GCC to comply with the ISO C23 standard, the most recent standard, which will ensure that our program is maximally portable and can be compiled on other standards-complying compilers without too much hassle.

  * On Windows only, we should add the flag **-D__USE_MINGW_ANSI_STDIO=1**, which will ensure that printing to the terminal follows the C standard.

**NOTE:**  The string **${workspaceFolder}** will automatically be replaced with the current workspace folder, so this will configure debugging sessions so that your program opens files from that folder.
