Mac版 VS code 关于建立头文件与引用

随意建立一个文件夹  用VS code 打开该文件夹而不是文件 

然后随意写个包含类定义的头文件(保存在刚建立的新文件夹)
如代码块1

// Fig. GradeBook.h
#include <iostream>
#include <string>
using namespace std;

class GradeBook
{
  public:
    GradeBook(string name)
    {
        setCourseName(name);
    }

    void setCourseName(string name)
    {
        courseName = name;
    }
    string getCourseName()
    {
        return courseName;
    }
    void dispalyMessage()
    {
        cout << "Welcome to the grade book for\n"
             << getCourseName() << "!" << endl;
    }

  private:
    string courseName;
};

接下来在用使用main函数的cpp文件中引用即可

#include <iostream>
#include "GradeBook.h"
using namespace std;

int main(int argc, char const *argv[])
{
    GradeBook gradeBook1("CS101 Introduction to C++ Programming");
    GradeBook gradeBook2("CS102 Data Structures in C++");

    cout << "gradeBook1 created for course : " << gradeBook1.getCourseName()
        << "\ngradeBook2 created for course : " << gradeBook2.getCourseName() << endl;
    return 0;
}
