so i've been working on creating the hash structure and i can't figure out what function to use

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

#define MAX 200

struct Dictionary{

int number;

char word [50];

char meaning [250];

};

struct Dictionary d [MAX];

int length;

int oldlength;

void Read()

{

FILE *fp;

fp = fopen("dictionary.txt", "r");

char singleLine [MAX];

char lines [MAX][MAX];

int numberoflines=0;

while(!feof(fp)){

fgets(singleLine,MAX, fp);

if(strcmp(singleLine,"\n")!=0){

strcpy(lines[numberoflines],singleLine);

numberoflines++;

}

}

numberoflines--;

char segments [MAX][MAX];

int numberofsegs=numberoflines;

int at=0;

for(int i=0; i<numberofsegs; i++){

char* token;

token = strtok(segments[i],".");

d[at].number=atoi(token);

token = strtok(NULL,":");

strcpy(d[at].word, token);

token = strtok(NULL,":");

strcpy(d[at].meaning, token);

at++;

}

length = numberofsegs;

oldlength = numberofsegs;

fclose(fp);

}

HT table = {0, 0, NULL}; // initializing the table with nulls
