I'm having lots of errors in my final project (a poker and black jack sim). I'm using a vector to implement the "hands" in the blackJack class, and I'm using a structured data type declared in another class, which is publicly inherited. The error I'm worried about is the compiler I'm using telling me that I'm not declaring a type in the vector.
blackJack header file:
#ifndef BLACKJACK_H
#define BLACKJACK_H
#include <vector>
#include "card.h"
class blackJack: public cards
{
private:
vector <Acard> playerHand;
vector <Acard> dealerHand;
public:
blackJack();
void dealHands();
void hitOrStay();
void dealerHit();
int handleReward(int);
void printHands();
};
#endif
card header file (this is the class black jack inherits from):
#ifndef CARD_H
#define CARD_H
const char club[] = "\xe2\x99\xa3";
const char heart[] = "\xe2\x99\xa5";
const char spade[] = "\xe2\x99\xa0";
const char diamond[] = "\xe2\x99\xa6";
//structured data to hold card information
//including:
// a number, representing Ace-King (aces low)
//a character, representing the card's suit
struct Acard
{
int number;
char pic[4];
};
// a class to hold information regarding a deck of cards
//including:
//An array of 52 Acard datatypes, representing our Deck
//an index to the next card in the array
//a constructor initializing the array indices to Ace-king in each suit
//a function using random numbers to shuffle our deck of cards
//13 void functions to print each card
class cards
{
private:
Acard Deck[52];
int NextCard;
public:
cards();
Acard getCard();
void shuffleDeck();
void cardAce(char[]);
void cardTwo(char[]);
void cardThree(char[]);
void cardFour(char[]);
void cardFive(char[]);
void cardSix(char[]);
void cardSeven(char[]);
void cardEight(char[]);
void cardNine(char[]);
void cardTen(char[]);
void cardJack(char[]);
void cardQueen(char[]);
void cardKing(char[]);
};
#endif
您忘了将std::
namespace前缀添加到vector
类名称。
use:
std::vector <Acard> playerHand;
everywhere qualify it by std::
or do:
using std::vector;
in your cpp file.
You have to do this because vector
is defined in the std
namespace and you do not tell your program to find it in std
namespace, you need to tell that.
您需要使用其命名空间( std
)限定vector
,或者在CPP文件的顶部导入命名空间:
using namespace std;
Also you can add #include<vector>
in the header. When two of the above solutions don't work.
