strtok????

[Lee125]

can any one explain this?
i didnt understand clearly.

/* strtok example */
#include <stdio.h>
#include <string.h>

int main ()
{
  char str[] ="- This, a sample string.";
  char * pch;
  printf ("Splitting string \"%s\" into tokens:\n",str);
  pch = strtok (str," ,.-");
  while (pch != NULL)
  {
    printf ("%s\n",pch);
    pch = strtok (NULL, " ,.-");
  }
  return 0;
}

What is it that you don't understand?

Did you run the program?

Line 10 will tokenize str based on the list of delimiters and return a pointer to the start of the string.

Line 11 loops until the trailing null pointer (end of string) is returned by strtok.

Line 14 advances pch to the next token.
