strok is not properly tokenizing words - c

Question

I am attempting to tokenize and store separate words into an array but for some reason the first word gets stored in index 0 and the rest of the words are not tokenized and are all stored in index 1.
I have the following code....
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
int main(int argc, char const *argv[])
{
char input[300];
while (1)
{
printf ("\nEnter input to check or q to quit\n");
fgets(input, 300, stdin);
for (int j = 0; j < 300; j++)
{
input[j] = tolower(input[j]);
}
/* remove the newline character from the input */
int i = 0;
while (input[i] != '\n' && input[i] != '\0')
{
i++;
}
input[i] = '\0';
/* check if user enter q or Q to quit program */
if ( (strcmp (input, "q") == 0) || (strcmp (input, "Q") == 0) )
break;
//printf ("%s\n", input);
/*Start tokenizing the input into words separated by space
*The tokenized words are added to an array of words*/
char delim[] = " ";
char *ptr = strtok(input, delim);
int j = 0 ;
// allocate our array
char *wordList[15];
for (i = 0 ; i < 16; i++)
{
wordList[i] = (char *) malloc(sizeof(char) * 300);
}
while (ptr != NULL)
{
strcpy(wordList[j], ptr);
printf ("%s\n", wordList[j]);
ptr = strtok(NULL, delim);
j++;
}
printf ("%s\n", wordList[1]);
}
printf ("\nGoodbye\n");
return 0;
}
Expected output
hello
there
sir
Output I'm getting
hello
there sir
Any help is greatly appreciated. Thanks.

Answer 1

This loop
// allocate our array
char *wordList[15];
for (i = 0 ; i < 16; i++)
{
wordList[i] = (char *) malloc(sizeof(char) * 300);
}
is bad because it is writing to wordList[15] while only wordList[0] to wordList[14] are available.
delim may be placed just after wordList and writing to this out-of-range wordList[15] may break the contents of delim.
Increase the number of elements
// allocate our array
char *wordList[16];
for (i = 0 ; i < 16; i++)
{
wordList[i] = (char *) malloc(sizeof(char) * 300);
}
Or decrease the number of iteration.
// allocate our array
char *wordList[15];
for (i = 0 ; i < 15; i++)
{
wordList[i] = (char *) malloc(sizeof(char) * 300);
}
