MacOS vscode 缺省源&配置文件

MacOS 的 vscode 配置。ubuntu 的到时候再说。

缺省源

{
	// Place your snippets for cpp here. Each snippet is defined under a snippet name and has a prefix, body and 
	// description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
	// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the 
	// same ids are connected.
	// Example:
	// "Print to console": {
	// 	"prefix": "log",
	// 	"body": [
	// 		"console.log('$1');",
	// 		"$2"
	// 	],

本机：MacBook Pro (13-inch, M1, 2020)

这里的 g++ 和 gcc 用的其实是 clang++ 和 clang 。

没有万能头文件，需要自己去 bits/ 目录下新建一个 stdc++.h 。
