在CodeBlocks錯誤中得到這個錯誤：數組下標的無效類型'main（）:: fields [int]'

Question

嗨，我是一個begginer，我正在閱讀「Beggining C++ through game programming」（第3版）。這實際上是來自書籍，每一行的代碼，並且我在標題中遇到錯誤。上線路24（串theHint = HINT [選擇] [HINT]; //對於字HINT）

我使用的碼塊

 #include<iostream> 
    #include<cstdlib> 
    #include<string> 
    #include<ctime> 

    using namespace std; 

    int main() 
{ 

    enum fields {WORD, HINT, NUM_FIELDS}; 
    const int NUM_WORDS=5; 
    const string WORDS[NUM_WORDS][NUM_FIELDS]= 
    { 
    {"wall", "Do you feel you're banging your head against something?"}, 
    {"glasses","These might help you see the answer."}, 
    {"labored","Going slowly, is it?"}, 
    {"persistent", "Keep at it."}, 
    {"jumble", "It's what the game is all about"} 
    }; 

    srand(static_cast<unsigned int>(time(0))); 
    int choice=(rand()% NUM_WORDS); 
    string theWord=WORDS[choice][WORD]; //WORD TO GUESS 
    string theHint=HINT[choice][HINT]; //HINT FOR WORD 

    string jumble=theWord; //jumbled version of word 
    int lenght=jumble.size(); 
    for(int i=0;i<lenght;++i) 
    { 
     int index1=(rand()%lenght); 
     int index2=(rand()%lenght); 
     char temp=jumble[index1]; 
     jumble[index1]=jumble[index2]; 
     jumble[index2]=temp; 
    } 
    //WELCOMING THE PLAYER 
    cout<<"\t\t\tWelcome to Word Jumble!\n\n"; 
    cout<<"Unscramble the letters to make a word.\n"; 
    cout<<"Enter 'hint' for hint.\n"; 
    cout<<"Enter 'quit' to quit the game.\n\n"; 
    cout<<"The jumble is: "<<jumble; 

    string guess; 
    cout<<"\n\nYour guess: "; 
    cin>>guess; 

    //ENTERING THE GAME LOOP 

    while((guess !=theWord)&& (guess!="quit")) 
    { 
     if(guess=="hint") 
     { 
      cout<<theHint; 
     } 
     else 
     { 
      cout<<"Sorry that's not it."; 
     } 
     cout<<"\n\nYour guess: "; 
     cin>>guess; 
    } 

    if(guess==theWord) 
    { 
     cout<<"\nThat's it! You guessed it!\n"; 
    } 
    cout<<"\nThanks for playing. \n"; 

    return 0; 
}

你想

WORDS[choice][HINT] 

因爲WORDS，作爲陣列，都有它的話和提示。
