我正在尝试将一个文件(充满一个单词，后跟一个换行符)读取到一个充满指向每个字符串的指针的数组。然后打印数组中的每个单词，并统计读取的单词数。然而它只是不打印任何单词并说导入了 0 个单词。
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#define ARGS_REQUIRED 2
#define MAX_WORDS 50
#define MAX_WORD_LENGTH 1024
void read_file (char * argv[], char word_storage[]);
void usage (char * argv[]);
int main (int argc, char* argv[])
{
char word_storage[MAX_WORDS];
if (argc == ARGS_REQUIRED)
{
system("clear");
read_file(&argv[1], word_storage);
}
else
{
usage(&argv[0]);
}
return 0;
}
void usage (char * argv[])
{
printf("Incorrect usage, try: ./program_name %s\n", argv[1]);
}
void read_file (char * argv[], char word_storage[])
{
FILE * file_name;
char *word[MAX_WORDS][MAX_WORD_LENGTH];
int word_count = 0, i = 0, j;
if ((file_name = fopen(argv[0], "r")) == NULL)
{
printf("Cannot open file ... \n");
}
while (fscanf(file_name, "%s", *word[MAX_WORDS]) == 1)
{
for (j = 0; j < MAX_WORDS; j++)
{
if (printf("%s\n", *word[j]) == 1)
{
word_count++;
}
}
}
fclose(file_name);
printf("Imported words: %d\n", word_count);
}
最佳答案
您可以按如下方式修改您的程序。这对我有用。请为 printf() 函数添加错误检查。
void read_file (char * argv[], char word_storage[])
{
FILE * file_name;
char word[MAX_WORDS][MAX_WORD_LENGTH];
int word_count = 0, i = 0, j;
if ((file_name = fopen(argv[0], "r")) == NULL)
{
printf("Cannot open file ... \n");
}
while (fscanf(file_name, "%s", word) == 1)
{
printf("%s\n",word);
word_count++;
/*
for (j = 0; j < MAX_WORDS; j++)
{
if (printf("%s\n", word[j]) == 1)
{
word_count++;
}
}
*/
}
fclose(file_name);
printf("Imported words: %d\n", word_count);
}
