vs创建C++模板

在使用C++做题的时候发现每次都要打一遍模板文件，或者复制，这样的操作有点烦。vs中有一个自定义模板可以帮我们解决这个问题

1. 点击左下角齿轮，选择user snippets

输入cpp.json，回车 

复制以下代码

{
	// 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"
	// 	],
	// 	"description": "Log output to console"
	// }
	"C++ template": {
		"prefix": "cpp",
		"body": [
			"#include ",
			"#include ",
			"using namespace std;",
			"int main(){",
			"",
			"treturn 0;",
			"}"
		],
		"description": "C++模板"
	}
}

prefix表示前缀，我这里用的是cpp来带出模板文件，body是带出的内容，description是描述，可以自由修改，"t"是加一个tab，控制缩进
