当创建结构时，我很难为结构初始化一个空数组。

pragma solidity ^0.5.1;

contract Board {

    //storage
    Post[] posts;

    //struct
    struct Post {
        address author;
        string title;
        string content;
        Comment[] comments;
    }

    struct Comment {
        address author;
        string comment;
    }

    //add-post
    function addPost(address _author, string memory _title, string memory _content) public {
        posts.push(Post(_author, _title, _content, /* HERE IS THE PROBLEM POINT */));
    }
}

我想用空数组（类型：注释）初始化注释（结构成员）。我应该使用哪个代码来解决问题点？
