hi
i have problem with add function in flight class

#include <iostream>
#include <string>
using namespace std;
class flight {
public:
	flight(); // constructor
	~flight();// destructor
	void Add_List();
	void Print_List();
	void Search_List();
	void Delete_List();
private:
	string mabda;
	string maghsad;
	 long int shomareParvaz;

};
struct list{
	list *next;
	list *prev;
	list *temp;
	list *tempezafi;


};	list *head;

flight::flight(){
	head=NULL;
}

flight::~flight(){
	list *temp=head;
	while ( temp != NULL ){
		list *tempezafi=temp;
		temp=temp->next;
		delete tempezafi;

	
	}
	
}

void flight::Add_List(string md , string ms ,  long int sp){
	if ( head == NULL ) {
		head = new list (md , ms , sp );
		system ("cls");
           cout <<" \t Data Succesfully Added"<<endl;
		   system("Pause");
		   system("cls");
	
	}
	else {
	list *temp = head; 
	while ( temp->next != NULL ){
		temp = temp->next;
		temp = new list (md , ms , sp);
		cout <<" \t Data Succesfully Added\n"<<endl;
		   system("Pause");
		   system("cls");
	}


	}


}

...
error C2511: 'void flight::Add_List(std::string,std::string,long)' : overloaded member function not found in 'flight'
can some one help me?

Hi there,

My guess is that you need to put the argument datatypes in the method prototype:

//line 8
void Add_List(string, string, long);

Hope that helps.

All the best,

The parameters are missing from the function declaration.

@ NwN & Peter87 thanks
i changed line 8 and now i get this error :
error C2661: 'list::list' : no overloaded function takes 3 arguments
can i insert "struct list" in private and add my argument in structure??
There is another way to solve this problem?

I believe you are not using list as you're supposed to.

The ways to create a list are described here:
http://www.cplusplus.com/reference/stl/list/list/

You can find plenty of examples to use lists here:
http://www.cplusplus.com/reference/stl/list/ (check the methods)

Maybe someone more advanced then myself can give you an alternative solution without lists.

All the best,
NwN
