Thread: Understanding strtok from string.h library

From my book I did the following example

Code:

#include <stdio.h>
#include <string.h>

int main()
{
  char string[] = "This is a sentence with 7 tokens";
  char *tokenPtr;

  printf( "%s\n%s\n\n%s\n",
          "The string to be tokenized is:", string,
          "The tokens are:" );

  tokenPtr = strtok( string, " " );

  while ( tokenPtr != NULL ) {
    printf( "%s\n", tokenPtr );
    tokenPtr = strtok( NULL, " " );
  }

  return 0;
}

What I'm noticing is that the token isn't being saved to a new array. A pointer is just pointed at the existing array. If that is the case how come printf doesn't print everything after tokenPtr? You would expect %s to print the whole array no?
