strtok equiavalent in C++ ?

[tvn007]

// I am using strtok to break the string
// For example: to extract 5 from the string below:
// TEST 1,P,5,PASS
// Below is my code in C:


ptr =strtok(testbuff," \t\n,()");
ptr =strtok(NULL," \t\n,()");
ptr =strtok(NULL," \t\n,()");
ptr =strtok(NULL," \t\n,()");

// My question: is there a better way to do this in C++,
// assumed testbuff is C++ string type.

// Thanks in advance for any hint,

Check out the Boost Tokenizer library
(http://www.boost.org/libs/tokenizer/).

Cheers! --M

The std::string member function find_first_of can do the job of
strtok.

std::string::size_type i = 0;
i = testbuff.find_first_of(" \t\n,()", i);
i = testbuff.find_first_of(" \t\n,()", i);
i = testbuff.find_first_of(" \t\n,()", i);
i = testbuff.find_first_of(" \t\n,()", i);

Oops. Sorry. That was utter rubbish.

In addition, a chapter of _Accelerated C++_ (Koenig, Moo) is
devoted to developing a standard algorithm style template
function for splitting sequences into subsequences.
