我想在VS配置一个c++模板（毕竟每次手写都很麻烦），这是我的.json文件：

{
	"Print to conaole":{
	"prefix": "cpp", //在新建立的页面中输入C++就会有智能提示，Tab就自动生成好了
	"body": [
	"#include <bits/stdc++.h>",
	"#define int long long",
	"#define lsf(a) scanf("%lld", &a)",
	"#define lpf(a) printf("%lld", a)",
	"#define dsf(a) scanf("%lf", &a)",
	"#define dpf(a) printf("%lf", a)",
	"#define csf(a) scanf("%c", &a)",
	"#define cpf(a) printf("%c", a)",
	"#define ssf(a) scanf("%s", a)",
	"#define spf(a) printf("%s", a)",
	"using namespace std;", //标准命名空间
	"",
	"signed main()", //main()函数
	"{",
	"    $0", //最终光标会在这里等待输入
	"	return 0;"
	"}",
	"",
	],
	"description": "A cpp file template." //用户输入后智能提示的内容
	}
}

然后，我想象的：

#include <bits/stdc++.h>
#define int long long
#define lsf(a) scanf("%lld", &a)
#define lpf(a) printf("%lld", a)
#define dsf(a) scanf("%lf", &a)
#define dpf(a) printf("%lf", a)
#define csf(a) scanf("%c", &a)
#define cpf(a) printf("%c", a)
#define ssf(a) scanf("%s", a)
#define spf(a) printf("%s", a)
using namespace std;

signed main()
{

    return 0;
}

实际是这样的：

#include <bits/stdc++.h>
#define int long long
#define lsf(a) scanf(
, &a)
#define lpf(a) printf(
, a)
#define dsf(a) scanf(
, &a)
#define dpf(a) printf(
, a)
#define csf(a) scanf(
, &a)
#define cpf(a) printf(
, a)
#define ssf(a) scanf(
, a)
#define spf(a) printf(
, a)
using namespace std;

signed main()
{
    
    return 0;
}

这是咋回事捏？求助（悬关）！
