## strtok

Syntax:

        #include <cstring>
        char *strtok( char *str1, const char *str2 );

The strtok() function returns a pointer to the next “token” in str1, where str2 contains the delimiters that determine the token. strtok() returns NULL if no token is found. In order to convert a string to tokens, the first call to strtok() should have str1 point to the string to be tokenized. All calls after this should have str1 be NULL. For example:

         char str[] = "now # is the time for all # good men to come to the # aid of
      their country";
         char delims[] = "#";
         char *result = NULL;
         result = strtok( str, delims );
         while( result != NULL ) {
             printf( "result is \"%s\"\n", result );
             result = strtok( NULL, delims );
         }

The above code will display the following output:

         result is "now "
         result is " is the time for all "
         result is " good men to come to the "
         result is " aid of their country"
