如何让我的系统检测输入单词是否在数组中

Question

#include <stdio.h>
#include <string.h>

//Detect Number Function
int hasNumbers(const char *word) {
    int len = strlen(word);
    for (int i = 0; i < len; i++) {
        if (word[i] >= '0' && word[i] <= '9') {
            return 1; // Found a digit
        }
    }
    return 0; // No digits found
}

//Detect Symbol Function
int containsSymbol(const char *word) {
    while (*word) {
        if ((*word >= 'A' && *word <= 'Z') || (*word >= 'a' && *word <= 'z') || (*word >= '0' && *word <= '9') || *word == ' ') {
            word++;
        } 
        else {
            return 1; // Symbol found
        }
    }
    return 0; // No symbols found
}

//Detect Centre Letter
int containsLetterL(const char *word) {
    for (int i = 0; word[i] != '\0'; i++) {
        if (word[i] == 'C' || word[i] == 'c') {
            return 0;  // 'L' or 'l' found
        }
    }
    return 1;  // 'L' or 'l' not found
}

//Detect Word in Array
int isWordInArray(char word[], char words[100][100], int wordCount) {
    for (int i = 0; i < wordCount; i++) {
        printf("CATS\n");
        if (strcmp(word, words[i]) == 0) {
            return 0;  // Word is found in the array
        }
        printf("DOGS\n");
    }
    return 1;  // Word is not found in the array
}

/*
int isWordInArray2(char word[100], char words[100][100], int wordCount) {
    for (int i = 0; i < wordCount; i++) {
        if (strcmp(word, words[i]) == 0) {
            return 1;  // Word is found in the array
        }
    }
    return 0;  // Word is not found in the array
}
*/

int main () {
    
    //Transfer Word in Text File to Array
    FILE *file;
    char wordA1[100]; // Assuming a maximum word length of 99 characters
    char words_array[100][100]; // Assuming a maximum of 100 words in the file
    
    // Open the file for reading
    file = fopen("wordlist_Game1.txt", "r");
    if (file == NULL) {
        printf("File not found or cannot be opened.\n");
        return 1;
    }
    
    int wordCountTextFile = 0;
    // Read words from the file and store them in the array
    while (fscanf(file, "%99s", wordA1) == 1) {
        strcpy(words_array[wordCountTextFile], wordA1);
        wordCountTextFile++;
    }
    // Close the file
    fclose(file);
    
    // Main Program
    char word[100];
    int wordCount = sizeof(word) / sizeof(words_array[0]);
    while (1) {
        printf("\nHere is your puzzle:\n");
        printf(" C T U L H N A\n");
        printf("Guess a word or END to quit: ");
        scanf("%s", word);
        printf("%s\n", word);
        
        //Detect END
        if (strcmp(word, "END") == 0) {
            printf("You entered 'END.' Exiting the loop.\n");
            break;
        }
        
        //Detect Number
        else if (hasNumbers(word)) {
            printf("The word contains numbers.\n");
        }
        
        
        //Detect Symbol
        else if (containsSymbol(word)) {
            printf("The word contains symbols.\n");
        }
        
        //Detect Centre Letter
        else if (containsLetterL(word)) {
            printf("The word doesn't contains centre letter 'C'.\n");
        } 
        
        
        //Detect Word in Array
        else if (isWordInArray(word, words_array, wordCount)) {
            printf("%s is in the array.\n", word);
        }
        
        /*
        //Detect Word in Array
        else if (isWordInArray2(word, words_array, wordCount)) {
            printf("%s is NOT the array.\n", word);
        }
        */
    }   
}

此代码用于检测遵循这些规则的特定单词。除了 isWordInArray 函数之外，每个函数都可以正常工作。该函数的作用是检测数组中的单词if。我希望它告诉我该单词是否不是数组并重复循环。如果该单词在数组中，则系统将继续执行 if-else 语句。问题是它跳过了告诉我该单词是否在数组中的部分。所以是的

根本原因：isWordInArray() 由于多种原因未能正确执行：

1. isWordInArray() 在找到单词时返回 false，而在未找到单词时返回 true
2. 代码将“wordCount”作为参数传递给 isWordInArray()，但“wordCount”的计算结果为 1——而不是实际的字数。我们通过将 wordCountTextFile 传递给 isWordInArray() 来解决这个问题。我们从读取操作中获得了实际字数，那么为什么不使用它呢？

下面是代码的可编译、工作子集，并应用了修复和注释：

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

    /* Updated:  Added some troubleshooting print outs */

    for(i = 0; i < wordCount; i++) 
        printf("%d: %s\n", i, words[i]);

    for(i = 0; i < wordCount; i++) 
    {
