Question

因此，我正在用C ++编写一个函数，该函数是一个小型数据库，其中包含运动和饮食两个类。这两个类非常相似，基本上完全相同。无论如何，我正在尝试打印我的运动课的内容。但是，我收到一条错误消息，提示函数StoreDailyPlan未定义。这很有趣，因为这两个类都有自己的重载函数版本，并且Diet版本运行良好。

void Wrapper::storeWeeklyPlan(ofstream& outfile, list<DietPlan>& dietlist)
{
DietPlan Node;
list<DietPlan>::iterator it; //this is our iterator, a pointer to the nodes in our list.

for(it = dietlist.begin(); it != dietlist.end(); it++) // start it at beginning, watch until end, and iterate it.
{
    Node = *it;
    storeDailyPlan(Node, outfile);
} //Another error here

}

void storeWeeklyPlan(ofstream& outfile, list<ExercisePlan>& exerciselist)
{
ExercisePlan Node;
list<ExercisePlan>::iterator it;

for (it = exerciselist.begin(); it != exerciselist.end(); it++)
{
    Node = *it;
    storeDailyPlan(Node, outfile); //THIS IS THE ERROR LINE
}

}

void Wrapper::storeDailyPlan(DietPlan diet, ofstream& outfile)
{
    outfile << diet;
}

void Wrapper::storeDailyPlan(ExercisePlan exercise, ofstream& outfile)
{
    outfile << exercise;
}

上面是直接负责将信息打印到文件上的4个功能。下面是一些其他相关代码。

class Wrapper
{
public:
Wrapper();
~Wrapper();
void runApp();
private:
int displayMenu();
void doChoice(int choice, list<DietPlan>& dietList, list<ExercisePlan>& exerciselist);

void loadDailyPlan(DietPlan& diet, ifstream& infile);
void loadDailyPlan(ExercisePlan& exercise, ifstream& infile);

void loadWeeklyPlan(ifstream& infile, list<DietPlan>& dietlist);
void loadWeeklyPlan(ifstream& infile, list<ExercisePlan>& exerciselist);

void storeWeeklyPlan(ofstream& outfile, list<DietPlan>& dietlist);
void storeWeeklyPlan(ofstream& outfile, list<ExercisePlan>& exerciselist);

void storeDailyPlan(DietPlan diet, ofstream& outfile);
void storeDailyPlan(ExercisePlan exercise, ofstream& outfile);


list <DietPlan> dietlist; //doubly linked list of DietPlan nodes. This is where it lives.
list <ExercisePlan> exerciselist;
};

如果您想查看其他任何代码，请告诉我。就像我说的那样，重载功能的节食版本效果很好。

我得到的错误是标识符“ storeDailyPlan”未定义并且 'storeDailyPlan'：找不到标识符

我正在使用Visual Studio 2015。

Answer 1

您在Wrapper::定义之前输了storeWeeklyPlan。

Answer 2

storeWeeklyPlan的声明中有错字。

// Replace this
void storeWeeklyPlan(ofstream& outfile, list<ExercisePlan>& exerciselist)
// With this
void Wrapper::storeWeeklyPlan(ofstream& outfile, list<ExercisePlan>& exerciselist)

函数标识符是未定义的C ++
