need help with my C code for process_word and save_to_file

int process_word(char *filename, WORDSUMMARY *words, char *stopwords[]); this function opens and reads text file of name passed by *filename line by line. For each line, it gets each word, if it is not a stop word, check if it is already in array words->word_array, if yes, increases its frequency by 1, otherwise inserts it to the end of the word_array and set its frequency 1. Meantime, it updates the count information.

int save_to_file(char *filename, WORDSUMMARY *words); this saves the data of WORDSUMMARY words to file of name passed by filename in specified format.

code:

#include

#include

#include "myword.h"

#include "mystring.h"

typedef struct word {

char word[30];

int frequency;

} WORD;

typedef struct words {

WORD word_array[1000];

int line_count;

int word_count;

int keyword_count;

} WORDSUMMARY;

void set_stopword(char *filename, char *stopwords[])

{

// your implementation

char line[1000];

char delimiters[] = "., \t ";

char *token;

int i;

FILE *fp = fopen(*filename, "r");

if(fp == NULL)

{

perror("Error opening file");

return 0;

}

while(fgets(line, 1000, fp) != NULL)

{

token = (char*) strtok(line, delimiters);

while(token != NULL)

{

i = (int)(*token - 'a');

strcat(stopwords[i], token);

strcat(stopwords[i], ",");

token = (char*) strtok(NULL, delimiters);

}

}

}

// this function check if the word is contained in directory stopwords[]

// returns 1 if yes, 0 otherwise. It use function str_contain_word()

int contain_word(char *stopwords[], char *word)

{

if(word == NULL || *word == '\0')

return 0;

else {

return str_contain_word(stopwords[*word - 'a'], word);

}

}

// this function check if word is a word in string str,

// returns 1 if yes, 0 otherwise

int str_contain_word(char *str, char *word)

{

if (str == NULL || word == NULL) return 0;

char temp[20] = {0};

strcat(temp, ",");

strcat(temp, word);

strcat(temp, ",");

if(strstr(str, temp))

return 1;

else

return 0;

}

int process_word(char *filename, WORDSUMMARY *words, char *stopwords[])

{

const char delimiters[] = " .,;:!()&?- \t \"\'";

char line[1000];

char buf[128];

char *token;

int frequency;

FILE *fp = fopen(*filename, "r");

while(!feof(fp))

{

if(fgets(buf, sizeof(buf), fp));

printf("%s", buf);

}

while(fgets(line, MAX_LINE_LEN, fp) != NULL)

{

words->line_count++;

lower_case(line);

trim(line);

token = (char*) strtok(line, delimiters);

while (token != NULL)

{

if(contain_word(stopwords, token) == 0)

{

}

token = (char*) strtok(NULL, delimiters);

}

}

}

int save_to_file(char *filename, WORDSUMMARY *words)

{

// your implementation

FILE *fp = fopen(*filename, "r");

fprintf(fp, "%-20s %8d ", "Word count", words->word_count);

fprintf(fp, "%-20s %8d ", "Keyword count", words->keyword_count);

fprintf(fp, "%-18s %10s ", "Keyword", "frequency");

// your implementation

for(int i = 0; i < (*words).keyword_count; i++)

{

fprintf(fp, "%-20s %8d ", words->word_array[i].word, words->word_array[i].frequency);

}

return 1;

}

output should look like this if everything works:

Line count 2 Word count 10 Keyword count 3 Keyword frequency first 1 test 2 second 1
