The strtok() function breaks a string into a series of tokens using a list of delimiters.

Note: strtok() only works on C-style strings of type char str[];, not C++ style strings of type string str;.

Syntax

char *token = strtok(string, delimiter);

The strtok() function splits the C-style string parameter into tokens based on one or more delimiters, and returns the pointer to the first token.

Subsequent calls to strtok(), with string set to NULL, return a pointer to the next tokenized string. When there are no tokens left to retrieve, a NULL pointer is returned.
