帮助我，Obi C Kenobi ......

我是C ++新手，我可能会犯一些C ++新手的错误， 因为我是新手，我不知道这个错误会是什么意思是。 我正在使用DevCpp来编译它。线索欢迎。 Ed。You''re my only hope!OK, I gots a mystery on my hands. I''m hoping someone can tell me justwhat the **** is going on here.I''m familiar with other object oriented programming tools, such as Java& REBOL. In an effort to become more familiar with C++, I decided towrite an object oriented BlackJack program. After writing some staticroutines for Faces and Suits, I turned my attention to creating Cardsand Hands. Cards were no problem, Hands are starting to tick me off. :)First, my header file for Hands:================================================== ====================#ifndef _Hand_H_#define _Hand_H_#include "Card.h"class Hand {public:Hand();bool add(Card prmCard);bool canDouble();bool canSplit();int getSize();int getValue();bool isBlackjack();bool isBusted();bool isSoft();void setHidden(int prmHideNo);string toString();string toString(bool prmLong);private:bool clsSoft;int clsCount;int clsHidden;Card clsCards[0];}#endif //_Hand_H_================================================== ====================Next, my C++ file for Hands:================================================== ====================#include <cstdlib>#include <iostream>#include <string>using namespace std;// Declarations...#include "Hand.h"// Definitions...int clsCount;int clsHidden;bool clsSoft;Card clsCards[0];// Constructors...Hand::Hand( ) {}// Methods....... All methods are currently stubs.================================================== ====================Please notice the "definitions" section. When compiled, it produces thefollowing error: "extraneous `int'' ignored."When I remove all definitions in that section, I get:----------------------------------------------------------------------12 Hand.cpp new types may not be defined in a return type12 Hand.cpp return type specification for constructor invalid----------------------------------------------------------------------But when I change the definition section to remove the first, and onlyfirst, int declaration, so that it looks like this:================================================== ====================// Definitions...clsCount;int clsHidden;bool clsSoft;Card clsCards[0];================================================== ====================It compiles successfully!AND! More entertainingly! If I switch the declarations around so thatthe bool is first, like this:================================================== ====================// Definitions...bool clsSoft;int clsCount;int clsHidden;Card clsCards[0];================================================== ====================I get the error: "''bool'' is now a keyword." But, once again, like int,leaving the bool keyword out compiles successfully.What''s going on?I''m a C++ newbie, and I''m probably making some kinda C++ newbie mistake,but because I a newbie, I''ve got no idea what that mistake might be.I''m using DevCpp to compile this.

You need a semi-colon here, and you haven''tput one in. #endif // _ Hand_H_ ============================================= ===== ==================== 接下来，我手中的C ++文件： =============================================== === ==================== #include< cstdlib> #include< iostream> ; #include< string> using namespace std; //声明...... #include" Hand.h"#endif //_Hand_H_================================================== ====================Next, my C++ file for Hands:================================================== ====================#include <cstdlib>#include <iostream>#include <string>using namespace std;// Declarations...#include "Hand.h" 因此，当编译器到达此处时，它希望您将名称 命名为Hand。它认为你在宣布。因此有趣的 结果。So when the compiler gets here, it is expecting you to give the namethe the "Hand" that it thinks you are declaring. Hence the funnyresults. //定义...... int clsCount; int clsHidden; bool clsSoft; Card clsCards [0];// Definitions... int clsCount; int clsHidden; bool clsSoft; Card clsCards[0]; Ed Dana schrieb：Ed Dana schrieb: 你是我唯一的希望！ 好​​吧，我手上有一个谜。我希望有人可以告诉我 ****这里发生了什么。You''re my only hope!OK, I gots a mystery on my hands.
