help please. to list words and.....

Hi there.
i got this program to do 4 an assignment...i finished up to a part, but i can't seem to do the final bit....the program is supposed to display the word of each sentence as a list on the screen and stating which sentece the words belong to.eg

sentence 1
word
word
sentence2
word
word .....and so on

if the paragraph has puncutation characters it should not be listed in the list.

i know'i'm asking too much but i was trying all nite last nite and all day today to figure it out........PLEASE HELP
thank you




#include <stdio.h>
#define max_char 100

main(){
char para[max_char];
int len_sent,i,count,unit;

printf("Please enter a paragraph\n");
fflush(stdin);
gets(para);

len_sent = strlen(para);
count=0;

for(i=0;i<len_sent;i++) {
if (para[i]=='.'){
count++;
}
}

printf("the number of sentences are: %d\n", count );

count=1;

for(i=0;i<len_sent;i++){
if (para[i]== ' ') {
count++;
}
}
printf("The number of words in the paragraph are %d\n",count);
}

Hmmm well first of all I see evil old gets() in your program (step slowly away from the computer and it may not attack). Also , you are only checking for periods as far as punctuation goes. There are many ways of doing this sort of thing. I remember seeing this done in "The C Programming Language" a couple of times. If you need to keep track of the sentences then you could create a struct like

Code:

---

struct whatever {
    char *sentence;
    char **white_space_array;
};

//skeleton code
void read(char *read_in_data, struct whatever *w) {
  int i, j;

  i = strlen(read_in_data);
  j = count_whitespace(read_in_data);
  w->sentence = (char *)malloc(i);
  if(!w->sentence)
        fprintf(stderr, "NULL allocation!\n");
    else
        strcpy(w->sentence, read_in_data);
    w->white_space_array = (char **)malloc(j * sizeof(char *));

    replace_all_whitespace_with_space_character(w->sentence);
    //now just use strtok or something to tokenize w->sentence and point w->white_space_array to each of the tokens.
}

Don't get mad because I didn't give specific code. It isn't my assignment, and nothing is gained from me doing everything for you.

Please use code tags when pasting code... see my signature for a link and an example.

@RAY:
Both of these are bad:
>fflush(stdin);
>gets(para);
Do a board search for more information.

You only need one loop. Read the data into your array (using fgets() instead of gets() ), then simply do something like this:

Code:

---

int Sentence = 1
Write "Sentence %d\n", ++Sentence;
For i = 0 to len(input)
    if input[i] == EndOfSentence
        Write "Sentence %d\n", ++Sentence;
    end if
    if (input[i] is part of a word)
        Write input[i]
    end if
    else if (input[i] is an end of word marker)
        Write '\n'
    end if
end for

Also, the code you supplied doesn't do what your assignment asks, as it doesn't actually print any words.... but I'm sure you knew this already ;)

@master5001: Your code has a nasty little bug:
>i = strlen(read_in_data);
>w->sentence = (char *)malloc(i);
>strcpy(w->sentence, read_in_data);
You blew the array buffer by forgetting to include 1 extra byte for the null terminator.
