Error: vector does not name a type

Question

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

You forgot to add std:: namespace prefix to vector class name.
