/* structure for a node */
/*Hello Erik,
 *
 * Thanks a lot for your time today.Please find the exercise below.Take your time and show me your inner C skills;)
 *
 * # The split
 *
 * In C, write a function that takes into input :
 * -a null terminated string
 *  - a character
 *  and returns an array of strings.
 *
 *  The array of strings will be the parts of the original string, separated by the character.
 *
 *  E.g.:
 *
 *  "qwe.try.cdsd”, ‘.' -> ["qwe", "try", "cdsd"]
 *
 *  Please let me know if anything was unclear!
 *
 *  Cheers,
 *  */
