strtok() - Manipulation Function

strtok() manipulation function is used to split a string into tokens. It returns a pointer to next token in the "str1", the characters of "str2" are the delimiters for the token. Function returns a NULL pointer if there are no tokens to return. When this function is called for the first time, "str1" point to string being tokenized and then a NULL pointer is used for "str1". Different delimiters can be used every time the strok() is called.

Syntax:

Example :

#include <stdio.h> #include <cstring.h> int main () { char str1[] = "Its* time*have* fun"; char str2[] = "*"; char * pnt; pnt=strtok( str1, str2 ); while( pnt!= NULL ) { printf( "Tokenized string using * is:: %s\n", pnt ); pnt = strtok( NULL, str2 ); } }

Result :
In the above example, "strtok()" manipulation function is used tokenize based on the delimiter "*". It splits it into tokens by the delimiters everytime it is called.
