c program not counting words properly

Vote count: 0

I have been trying to do a program that will count the number of words from a text file. I have been having problem with counting the words, I decided to create a function to do so because I will do other things with this program (I really want to create a text editor, but I am doing so piece by piece).

The problem is:

My program returns an enormous amount of counted words when I know the text file has a much lower word count. What I am really trying to learn here is how to iterate through characters in an array of strings[I][J].

Additional information:

1. The function that does the counting can print all the strings if I do a simple loop to print all the strings. That means it has passed the strings correctly.
2. I am sending the correct number of lines to the function, I have already double checked.

Here is my code:

#include <stdio.h>
#include <ctype.h>
#include <string.h>
#include <stdlib.h>
#define  MAX_LEN  10000

int main (int argc, char *argv[]) {

int  i = 0;
int  j = 0;
char content[MAX_LEN + 1];
int  totalWords = 0;
int  sentence = 0;
int  syl = 0;
int  totalLines = 0;
char **strings;
FILE *fp;

strings = malloc (sizeof(char *) * totalLines);
if (strings == NULL) {
   printf("Error: allocation failed\n");
   exit(0);
}

fp = fopen(argv[1], "r");
if (fp == NULL) {
   printf("Error opening file, file pointer is null\n");
   printf("Please try again with a new file\n");
   exit(0);
}

while(fgets(content, MAX_LEN, fp) ) {
   content[strlen(content) -1] = '\0';
   strings[i] = malloc ((sizeof(char*)) * (strlen(content)) +1 );
   strcpy(strings[i], content);
   i++;
   totalLines++;
   strings = realloc(strings, sizeof(char *) * (totalLines ) + 1 );
   if (strings == NULL) {
      printf("Error: memory reallocation failed\n");
      exit(0);
   }
}

totalWords = fWords(strings, totalLines);
printf("%d is the total of words\n", totalWords);

for (j = 0; j <= totalLines; j++) {
   free (strings[j]);
}
free(strings);
strings = NULL;
fclose(fp);

return 0;
}


int fWords (char **array, int index) {

int number;
int i  = 0;
int in = 0;
int j  = 0;
int length = 0;

while (i < index) {
length = strlen (array[i]);
   for (j = 0; array[i][j] <= length; j++) {
      if (isspace(array[i][j]) != 0) {
         in = 0;
      }
      else if (in == 0) {
         in = 1;
         number++;
     }
   }

  i++;
}

return number;
}
