vscode cpp snippets

cpp.json

{
	// 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:
	"main function with iostream": {
		"prefix": "main2",
		"body": [
			"#include <iostream>",
			"",
			"int main()",
			"{"
			"	$1",
			"",
			"	return 0;",
			"}"
		],
		"description": "c++ program template"
	},
	"atcoder template": {
		"prefix": "atcoder",
		"body": [
			"#include <bits/stdc++.h>",
			"using namespace std;",
			"int main()",
			"{"
			"	$1",
			"",
			"	return 0;",
			"}"
		],
		"description": "atcoder c++ program template"
	}
