Error C2512 - No Appropriate default constructor available, i thought i put on in help :( ???

[DriftKing13]

So i keep getting this error and ive included a constructor i think, any help to fix this issue would be greatly appreciated, im just trying to add an object to a vector and i know its not a good way but please focus on the issue I have and not how ugly my code is. thankyou.

#include <iostream>
#include <string>
#include <vector>
#include <fstream>
#include <algorithm>
#include <ctime>

#include "Dock.h"

using namespace std;

//time method using this way 
	time_t now = time(0);
	char* dt = ctime(&now);

	int entNum;
	string shipName;
	string shipSize;
	string shipRowPos;

	//creation of a new ship
	Ship newShip; <<<<<<<<<<<<<<<<<<<<<<< here is the error line :/

	//test just for debugging
	Row theRow;

	//Row vector.insert(Row vector.end(), Shipvector.begin(), Shipvector.end());

int main(int argc, char *argv[]) {

	fstream port;

	cout << "Welcome to Dock Manager v1.2" << endl;

	login();

	menu();

	cin >> entNum;

	switch (entNum)
	{
	case 1:	

	    port.open("portLog.txt", ios::in);

		cout << "Dock ship to port" << endl;
	
		cout << "Enter ship name" << endl;
		cin >> newShip.shipName;

		cout << "Enter ship size using S,M,L meaning Small, Medium or Large" << endl;
		cin >> newShip.shipSize;

		cout << "Ship Size: " << newShip.shipSize << ", and Ship Name: " << newShip.shipName << endl;

		theRow.dock(newShip);

		//open port log add ship with position and timestamp to portlog.txt
		//if no spaces for ships add to waiting list

		port << dt << " " << newShip.shipName << " " << newShip.shipSize << endl;; 

		break;
}
	port.close();

	cin.get();
	cin.ignore();

}

Line 22 tries to use the default constructor Ship(), which is not defined in the Ship class.

You can either make a default constructor or declare the newShip variable as a pointer. Ship *newShip;

thanks for the reply @smac89, however isnt the Ship(std::string shipName, std::string shipSize) a default contructor?

[Smac89]

No a default constructor is one that takes no parameters. Your constructor takes parameters, so it cannot be said to be the default constructor.

Note that if you didn't specify a constructor, then the default constructor is used. Since you have defined a constructor that is not the default constructor, the only way an object of type Ship can exist is if you create it with any of the of those constructors you have defined.

[DriftKing13]

Right I see when i make Ship(); the default constructor I get these errors :/ @smac89

1>Source.obj : error LNK2019: unresolved external symbol "public: __thiscall Ship::Ship(void)" (??0Ship@@QAE@XZ) referenced in function "void __cdecl `dynamic initializer for 'newShip''(void)" (??__EnewShip@@YAXXZ)

[Smac89]

Can you show how you are defined the constructor?
