带有 C++ header 的 VSCode 智能感知

我搜索过这个，但我找不到任何东西。如果是骗局，我会毫无问题地关闭我的问题。我在VSCODE中有一个c_cpp_properties.json配置文件

我正在 Ubuntu 16.04 中开发。我面临的问题是，当我输入 .cpp 文件时，标题的智能感知不起作用。

MyFooClass.h
#pragma once

#include <cstddef>
#include <fstream>
#include <string>

class MyFooClass
{
private:
    //My private fields

public:
    MyFooClass();
    virtual ~MyFooClass();
    bool MyFooFunction();
};

当我使用 MyFooClass.cpp 实现时

#include "MyFooClass.h"

Intellisense 不适用于 .h 中的函数和数据 在我看来，这应该在我的配置中默认启用，但我不知道是否必须添加一些新内容。非常感谢。
