【问题描述】:
我对 C 编程还很陌生,而且我不断收到这些我不知道的错误:
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
另外,代码如下:
#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);
}
}
提前谢谢你。
【问题讨论】:
-
我知道您是 C 新手。但是您似乎有一些基本错误,即使是新手也可以看到如果您真的仔细检查了您的代码。例如,
int word_search(char word[100], char str[100]);声明了一个带有两个参数的函数,但您使用四个参数调用它:word_search(&fileptr, word, &length, &num);。 -
并从
char* word[100]; int *length; int *num;中删除* -
编码时,一致缩进,不要使用制表符进行缩进。在每个左大括号“{”后缩进。在每个右大括号 '}` 之前不缩进。建议每个缩进级别使用 4 个空格。永远不要使用制表符,因为每个文字处理器/编辑器的制表位/制表符宽度设置不同
