如何修复C ++错误:预期的unqualified-id [英] How to fix C++ error: expected unqualified-id

问题描述

我在第6行遇到此错误:

I'm getting this error on line 6:

error: expected unqualified-id before '{' token

我不知道怎么了.

#include <iostream>

using namespace std;

class WordGame;
{               // <== error is here on line 6
public:

    void setWord( string word )
    {
        theWord = word;
    }
    string getWord()
    {
        return theWord;
    }
    void displayWord()
    {
        cout << "Your word is " << getWord() << endl;
    }
private:
    string theWord;
}


int main()
{
    string aWord;
    WordGame theGame;
    cin >> aWord;
    theGame.setWord(aWord);
    theGame.displaymessage();

}

推荐答案

此处不应使用分号:

class WordGame;

...但是在类定义的末尾应该有一个:

...but there should be one at the end of your class definition:

...
private:
    string theWord;
}; // <-- Semicolon should be at the end of your class definition
