警告：傳遞從兼容的指針類型「word_search」的參數1 [默認啓用]

我很新的C語言編程，我不斷收到這些錯誤，我有沒有線索：警告：傳遞從兼容的指針類型「word_search」的參數1 [默認啓用]

HW5_mkhan44.c: In function ‘main’: 
HW5_mkhan44.c:31:3: warning: passing argument 1 of ‘word_search’ from incompatible pointer type [enabled by default] 
HW5_mkhan44.c:9:5: note: expected ‘char *’ but argument is of type ‘struct FILE **’ 
HW5_mkhan44.c:31:3: warning: passing argument 2 of ‘word_search’ from incompatible pointer type [enabled by default] 
HW5_mkhan44.c:9:5: note: expected ‘char *’ but argument is of type ‘char **’ 
HW5_mkhan44.c:31:3: error: too many arguments to function ‘word_search’ 
HW5_mkhan44.c:9:5: note: declared here

而且，這裏是代碼：

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

int word_search(char word[100], char str[100]); 
int character_count(char curr_str[100]); 
void search_count(FILE *fpter, char c[100], int *len, int *result); 

int main(void) 
{ 
     FILE *fileptr; 
     char filename[100]; 
     char* word[100]; 
     int *length; 
     int *num; 

     printf("Please input the text file name: "); 
     scanf("%s", filename); 

     fileptr = fopen(filename, "r"); 



    if(fileptr == NULL) 
       printf("File does not exist"); 
     else{ 
       printf("Please enter a word to search: "); 
       scanf("%s", word); 
       word_search(&fileptr, word, &length, &num); 

       if(*num == 0){ 
         printf("Word exists in file"); 
         printf("There are %d characters in file", *length); 
       } 
       else 
         printf("Word does not exist in file"); 
     } 
     fclose(fileptr); 

     return 0; 
} 

int word_search(char word[100], char str[100]) 
{ 
     int num; 
     if(strcmp(word, str) == 0){ 
       num = 0; 
       return(num); 
     } 
     else{ 
       num = 1; 
       return(num); 
     } 
} 

int character_count(char current_str[100]) 
{ 
     int word_length; 

     word_length = strlen(current_str); 

     return(word_length); 
} 

void search_and_count(FILE *fpter, char c[100], int *len, int *result) 
{ 
     char line[120]; 

     while(fgets(line, sizeof(line), fpter)){ 
       char* t = strtok(line, " "); 
       *len = wordsearch(c, t); 
       *result = character_count(t); 
     } 
}

在此先感謝您。

我知道你是C的新手。但是看起來你有基本的錯誤，即使是新手也能看到你是否真的仔細檢查了你的代碼。例如，'int word_search（char word [100]，char str [100]）;'聲明一個帶有兩個參數的函數，然後用四個參數調用它：'word_search（＆fileptr，word，＆length，&num);'。 – kaylum

And remove '*'from char * word [100]; int * length; int * num;' – BLUEPIXY

編碼時，縮進一致，不要使用製表符縮進。縮進後每個大括號'{'。unindent before every closing括號'}'。爲每個縮進級別建議使用4個空格不要使用製表符，因爲每個文字處理器/編輯器的製表位/製表符寬度設置不同 – user3629249

你wordsearh功能有兩個參數的定義：

int word_search(char word[100], char str[100])

你用4個參數調用;

word_search(&fileptr, word, &length, &num);

不要想從主調用功能search_and_count？

謝謝！它現在正在工作。 –
