Thread: Arrays of Words

I'm trying to work on a program that takes a string as an input, parses it into words according to spaces and newline characters, puts each word in its' own space into a char array, then prints the array. However, what I've got so far only prints garbage characters past the first two or so characters.

This:

Code:

#include <stdio.h>
#include <string.h>

int main ()
{
        char wordlist[100][100];
        char templist[] = "This is a bunch of words";
        char *tokenptr;

        int wordcnt = 0;

        tokenptr = strtok(templist, " ");
        while (tokenptr != NULL)
        {
                if (tokenptr != " ");
                {
                        *wordlist[wordcnt] = *tokenptr;
                }
                if (tokenptr == " ");
                {
                        wordcnt++;
                }
                tokenptr = strtok(NULL, " ");
        }
        for (wordcnt = 0; wordcnt < 100; wordcnt++)
        {
                printf("&#37;s", wordlist[wordcnt]);
        }
}

outputs this:

Code:

Tiabowÿ=öÿ=ö¬ÿ=öÿ=ö ÿ?B@ÿ?@0ÿ;Á0ÿ¿ïÿ?@¸ÿ?B@ÿ?U°ÿ?@0ÿ¿ð,ÿ?{pÿ¿í¨

Any idea what I'm doing wrong here?

Ok, new problem. The old one was just me being stupid and unobservant.

Code:

#include <stdio.h>
#include <string.h>

int main ()
{

        char wordlist[100][100];
        char templist[1000];
        char *tokenptr;

        int wordcnt = 0, cnt;

        scanf("%s", &templist);

        tokenptr = strtok(templist, " ");
        while (tokenptr != "0")
        {
                strcat(wordlist[wordcnt], tokenptr);
                tokenptr = strtok(NULL, " ");
                wordcnt++;
        }

        for (cnt = 0; cnt < wordcnt; cnt++)
        {
                printf("%s ", wordlist[cnt]);
        }
}

When executed, it's supposed to read input from input.txt using I/O redirection.
Input.txt:

Code:

This is a test.
0

However, when I execute, all I get is a seg fault. I tried to change it from tokenizing when it hits NULL instead of a 0 in the string, but the change there is that it only read up to 'This' of input.txt.

What I was trying to do there is have it tokenize until it reaches a '0' in the string (The string will consist only of alphanumeric characters).
