我以某種方式改變ctype.h？

Question

#include <stdbool.h> 
#include <stdio.h> 
#include <stdlib.h> 
#include <string.h> 
#include <ctype.h> 

#include "dictionary.h" 

#define HASH_SIZE 5 

// prototype 
int hash(char *word); 

// counter 
int counter; 

// node 
typedef struct node 
{ 
    char word[LENGTH + 1]; 
    struct node *next; 
} node; 

// hash table 
struct node *hashtable[HASH_SIZE]; 



/* 
* Returns true if word is in dictionary else false. 
*/ 

bool 
check(const char *word) 
{ 
    //make a writable word (palabra) 
    int len = strlen(word); 
    char palabra[len + 1]; 
    //int i; 

    // make la palabra all lowercase letters 
    for (int i = 0; i < len; i++) 
    { 
     if (isalpha(palabra[i]) || palabra[i] == '\'') 
      palabra[i] = tolower(word[i]); 
    } 

    //palabra[i] = (char) "\0"; 

    // hash the word 
    int value = hash(palabra); 

    // let's look at the first node in the bucket 
    struct node *n; 
    if (hashtable[value] == NULL) 
     return false; 
    else 
     n = hashtable[value]; 

    // iterate through the bucket to see if the word is there 
    while (strcmp(palabra, n->word) != 0 && n->next != NULL) 
    { 
     n = n->next; 
    } 


    // if the word is found, print true, else false 
    if (strcmp(palabra, n->word) ==0) 
     return true; 
    else 
     return false; 
} 


/* 
* Loads dictionary into memory. Returns true if successful else false.

bool 
load(const char *dictionary) 
{ 
    // open the dictionary 
    FILE *dict = fopen(dictionary, "r"); 
    if(dict == NULL) 
    { 
     printf("Could not open %s.\n", dictionary); 
     return false; 
    } 

    // set all values in the hash table to null 
    for(int i = 0; i < HASH_SIZE; i++) 
    { 
     hashtable[i] = NULL; 
    }

    counter = 0; 

    // iterate through the words in the dictionary 
    while (!feof(dict)) 
    { 
     //declare a node 
     node *n = malloc(sizeof(node)); 

     // copy the word into the node 
     fscanf(dict, "%s", n->word); 

     // hash the word, baby! 
     int hash_value = hash(n->word); 

     // start saving addresses to the hashtable 
     n->next = hashtable[hash_value]; 
     hashtable[hash_value] = n;

      q = q->next;

    printf("Ending the test.\n"); 

    fclose(dict); 

    return true; 
} 


/*

    return counter;

    // hash value and length of word 
    int value = 0; 
    int len = strlen(word); 

    // iterate through letters, adding ASCII values 
    for(int i = 0; i < len; i++) 
    { 
     int letter = (int) word[i]; 
     value += letter; 
    } 

    // make sure the value is less than 100 & return 
    value = value%HASH_SIZE; 
    return value; 
} 

當我運行我的代碼，我收到此錯誤信息：

在文件中包含從/usr/include/ctype.h:28:0， 從speller.c：10： 在/ usr/include/bits/types.h：31：1：error：expected'='，'，';'，'asm'或'attribute'before'typedef'

這是否意味着我有以某種方式設法改變ctype.h庫？如果是這樣，我該如何解決它？

啊哈！戈登，你解決了它！我發現在#include的正上方輸入了一些導致問題的零散字符。謝謝！
