Thread: memory and strtok function!!

Hi!
the program below is supposed to accept a sentence, and then print out the words in that sentence. the program works fine, but in the end it gives me an error specifying that memory couldn't be read.
do I dismanage my memory here?

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(int arg, char* argv[]){
             char *sentence,words[5][200];
             int i = 0;
             sentence = (char*) malloc(sizeof(char) * 200);
             printf("Please enter your sentence(s):\n");
             gets(sentence);
             strcpy(words[i] , strtok(sentence," "));
             while (words[i]){
                   puts(words[i]);
                   i++;
                   strcpy(words[i] , strtok(NULL," "));
                   }
             system("PAUSE");
             return 0;
