strtok()() is used to iteratively parse a string into substrings.
The function should initially be called with both string and delimiter arguments, which does the following:
Subsequent calls to strtok() returns a new substring that extends from the end of the last substring returned to the next instance of any of the characters in delimiter . If none of the characters in delimiter are present in the string, the remainder of the string is returned. If there are no characters left to return, the function returns FALSE .
The string used in delimiter can be changed with every call to strtok() .
