c - 我的 while 循环上的错误代码，试图逐行读取文件。在C中

Question

我正在尝试从文件字典中获取输入，一次一行，我知道文件字典中的每一行只是一个单词。当我尝试编译此代码时收到错误代码，错误是:

dictionary.c:66:36:错误:不同指针类型的比较('char ' 和 'int ()(FILE *)') [-Werror,-Wcompare-distinct-pointer-types] while ( (fgets(word, 46, dic)) != feof )

我对编码非常陌生，如果我尝试使用错误的方法或者我只是错误地编码，我不确定是否可以通过这种方式完成。感谢您提前提供帮助。

bool load(const char* dictionary)
{
    char word[46];
    unsigned long key;

    //remember file name
    FILE* dic = fopen(dictionary , "r");
    if (dic == NULL)
        {
            printf("Could not open file..\n");
            return false;
        }
    while ( (fgets(word, 46, dic)) != feof )
        {
            numberWords++;
            //Save new word
            node* newWord = malloc(sizeof(node));
            strcpy(newWord->dicWords, word);
            newWord->next = NULL;
            //Use Hash function on new word found
            key = hash(word);
            //Enter word into Hashtable
            if ( hashTable[key] == NULL )
                {
                    hashTable[key] = newWord;
                }
            else
                {
                    newWord->next = hashTable[key];
                    hashTable[key] = newWord;
                }
        }

    fclose(dic);

    return false;

feof 是库函数的标识符。请更改

while ( (fgets(word, 46, dic)) != feof )

至

while ( (fgets(word, 46, dic)) != NULL )
