Why do I get such a messed up output?

I'm writing a program to print the occurrences of letters and (one, two, three letter, etc..) words. So far I've gotten the letter part to work properly but I can't get the word part to work at all let alone differentiate between one, two, or three letter words. I tried to find out where the program was messing up, and it seems to be at the point I try to store them in the array "word".

Someone suggested strlok() but didn't mention how.

EDIT: I've substituted strlen() with sizeof() and have set my 'i' variable = 0 where it should be, but my output remains the first letter of the whole string and some strange character.

    printf ( "enter some text\n");
    if ( fgets( textStream, sizeof ( textStream), stdin)) //input up to 99 characters
    {
        findLetters(textStream);
    }
    else

Solution

There are a few problems in you code:

for(;i < strlen(point); i++) //seperates strings from each other When this line is executed the value of i is already strlen and therefore the following for is not executed. Add i=0 to fix it.
You should use sizeof not strlen, otherwise you miss the last word.
if(point[i] == '.' || point[i] == 44|| point[i] == 46) you are not checking for ' ' here. The correct if condition should be: if(point[i] == ' ' || point[i] == '.'|| point[i] == ' ')
Your code does not take into account the case where you have a comma and a space together.
The algorithm you're using to find a word in the array is flawed. You should use something like this :

how_many_times(word[i], word, number_of_words);

int how_many_times(char * word, char words[50][100], int how_many_words) {
  int i = 0, counter=0;                                                                         
  for (i=0; i< how_many_words; i++) {
    if ( strcmp(words[i], word) == 0 ) {
      counter++;
    }
  } 
  return counter;
}
