不寻常的声明错误

Question

This seems like a really easy fix, but I can't understand what it's coming from.

Any help fully appreciated!

The following 2 lines of code produce the following errors respectively.

vector <spades::player> players(4, player());
vector <spades::card> deck(52,card());

error: 'player' was not declared in this scope
error: 'card' was not declared in this scope

Below is my card.cpp

#include <iostream>
#include <sys/ioctl.h>
#include <cstdio>
#include <unistd.h>
#include <locale.h>
#include <ncursesw/ncurses.h>

#include "card.h"
namespace spades {
card::card()
{
    cardSuit = 0;
    cardNum = 0;
}

card::card(int suit, int number)
{
    cardSuit = suit;
    cardNum = number;
}
}

Below is my player.cpp

#include <iostream> // Stream declarations
#include <vector> //Vectors used to store deck and players hands
#include <string> //String declarations
#include <algorithm> //Shuffle Method
#include <sys/ioctl.h>
#include <cstdio>
#include <unistd.h>
#include <locale.h>
#include <ncursesw/ncurses.h>
#include "player.h"
namespace spades {
using namespace std;


player::player() {
    score =0; //total score
    bid = NULL; //bid for that round
    tricksTaken = 0; //score for thast round
    sandBag = 0; //the number of points you win, more than what you bid, every 10th bag = -100
    doubleNil = false;
    for(int i=0; i<13; i++)
        hand.push_back(card());
}

void player::addCard(spades::card b){
    for (int i=0; i<hand.size(); i++){
        //compare card being played to the ones in your hand to search and determine which one to erase
        if((hand.at(i).getCardNum() == 0) &&
            (hand.at(i).getSuit() == 0))
        {
            hand.at(i).setCardNum(b.getCardNum());
            hand.at(i).setSuit(b.getSuit());
            return;
        }
    }
}

void player::removeCard(spades::card a) {
    for (int i=0; i<hand.size(); i++){
        //compare card being played to the ones in your hand to search and determine which one to erase
        if((hand.at(i).getCardNum() == a.getCardNum()) &&
            (hand.at(i).getSuit() == a.getSuit()))
        {
            hand.at(i).setCardNum(0);
            hand.at(i).setSuit(0);
            return;
        }
    }
}
}

Answer 1

The compiler is actually complaining about the arguments you pass to vector constructors. You specified player() and card() in the constructor arguments, while it is obvious that your types are actually named spades::player and spades::card . You correctly specified the spades:: part in template parameters. Why did you omit the spades:: part from the constructor arguments?

It should be

vector <spades::player> players(4, spades::player());
vector <spades::card> deck(52, spades::card());

It should be noted though that the explicit argument is unnecessary, so you can just do

vector <spades::player> players(4);
vector <spades::card> deck(52);

and get the same result.

Answer 2

Also you don't need the

    namespace spades {

    }

block in player.cpp, only around you class definition in the header file. Maybe you ment

    using namespace spades;
