c++ - 视觉 C++ : Compiler Error C4430

Question

Game.h代码:

#ifndef GAME_H
#define GAME_H

class Game
{
    public:
        const static string QUIT_GAME; // line 8
        virtual void playGame() = 0;
};

#endif

错误:

game.h(8): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
game.h(8): error C2146: syntax error : missing ';' before identifier 'QUIT_GAME'
game.h(8): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

我做错了什么？

Answer 1

你需要做两件事:

• #include <string>
• 将类型更改为 const static std::string QUIT_GAME (添加 std:: )
