strtok program crashing

Question

the program for strtok given on http://www.opengroup.org/onlinepubs/000095399/functions/strtok.html crashes everytime..

#include 
...
char *t         


        

Answer 1

Since this has a C++ tag:

// Beware, brain-compiled code ahead!
#include 
#include 
#include 

int main()
{
  std::istringstream iss("LINE TO BE SEPARATED");
  while( iss.good() ) {
    std::string token;
    iss >> token;
    std::cout << token '\n';
  }

  return 0;
}

Edit: As Konrad said in his comment, the above loop could be replaced by std::copy working on stream iterators:

// Beware, brain-compiled code ahead!
#include 
#include 
#include 
#include 

int main()
{
  std::istringstream iss("LINE TO BE SEPARATED");
  std::copy( std::istream_iterator(std::iss)
           , std::istream_iterator()
           , std::ostream_iterator(std::cout, "\n") );
  return 0;
}

I have to (grudgingly) admit that there's something to be said for it.
