對象構造函數調用未聲明在此範圍內

Question

I have managed to solve this myself by moving the #include for part_time.h to the top of the #include list. Why this made a difference, I have no idea.

我有我的分裂程序轉換成一個makefile後一個手動對象構建呼叫的問題。每個.cpp都有一個包含它的.h，main.cpp也包含每個.h。

相關代碼如下。錯誤是：

main.cpp: In function ‘void add_part_time()’: main.cpp:166:2: error: ‘part_time’ was not declared in this scope part_time part_time1(name, forklift, annual_leave, sick_leave); ^

main.cpp:166:12: error: expected ‘;’ before ‘part_time1’ part_time part_time1(name, forklift, annual_leave, sick_leave);

我注意到了一些奇怪的東西。如果我刪除了;在sick_leave定義行之後，我得到的唯一錯誤是同一個問題關於失蹤的問題;另一個錯誤消失。

#include <string> 
using namespace std; 

class employee 
{ 
    public: 
     static int count; 
     employee (std::string name); 
     string name; 
     ~employee(); 
}; 

employee::employee (string set_name) 
{ 
    name = set_name; 
} 

employee::~employee() 
{ 

} 

class dockhand: public employee 
{ 
    public: 
     dockhand (string set_name, bool set_forklift); 
     float start_shift; 
     bool forklift; 
     float payrate; 
     ~dockhand(); 
}; 

dockhand::dockhand (string set_name, bool set_forklift) : employee (set_name) 
{ 
    forklift = set_forklift; 
    start_shift = 4.00; 
} 

dockhand::~dockhand() 
{ 

} 

class part_time: public dockhand 
{ 
    public: 
     part_time (string set_name, bool set_forklift, int annual_leave, int sick_leave); 
     float end_shift; 
     int annual_leave; 
     int sick_leave; 
     ~part_time(); 
}; 

part_time::part_time (string set_name, bool set_forklift, int annual_leave, int sick_leave) : dockhand (set_name, set_forklift) 
{ 
    end_shift = 8.00; 
    payrate = 22.00; 
} 

part_time::~part_time() 
{ 

} 

void add_part_time() 
{ 
    string name; 
    bool forklift; 
    int annual_leave; 
    int sick_leave; 
    name = "bob"; 
    forklift = true; 
    annual_leave = 2; 
    sick_leave = 3; 
    part_time part_time1(name, forklift, annual_leave, sick_leave); 
} 

然而，完全相同的格式與另一個類編譯得很好。

void add_casual() 
{ 
    string name; 
    bool forklift; 
    name = "bob"; 
    forklift = true; 
    casual casual1(name, forklift); 
} 

我被困在什麼問題。註釋掉構造線會使其編譯，所以它絕對是一些東西。

編輯更改part_time part_time1（name，forklift，annual_leave，sick_leave）;行到隨便的構造函數調用使它與一個makefile很好地編譯。所以即使包含正確，該特定行仍然有問題。

我已經設法通過將#include for part_time.h移動到#include列表的頂部來解決這個問題。絕對沒有其他改變。爲什麼這有所作爲，我不知道。
