Working with strings

can you describe what this sequence is?

the code below, breaks the sequence into tokens delimited by spaces.

your description of how they are processed is confusing

   A1N
   c2
   t120
   d4
   t0
   b5
   t0
   a2
   t368
   e2
   t452
   1c
   t0
   e1
   t600
#include <stdio.h>
#include <string.h>

char str [] = "A1N c2 t120 d4 t0 b5 t0 a2 t368 e2 t452 1c t0 e1 t600";

int
tokenize (
    char *str,
    char *tok [],
    int   maxTok )
{
    char s [100];

    strcpy (s, str);

    tok [0] = strtok (s, " ");
    int  n;
    for (n = 1; n < maxTok; n++)
        if (NULL == (tok [n] = strtok (NULL, " ")))
            break;
    return n;
}


#define MAX_TOK  20

int
main ()
{
    char *tok [MAX_TOK];
    int n = tokenize (str, tok, MAX_TOK);

    for (int i = 0; i < n; i++)
        printf ("   %s\n", tok [i]);
}
