c++ - Int tokenizer

Question

I know there are string tokenizers but is there an "int tokenizer"?

For example, I want to split the string "12 34 46" and have:

list[0]=12

list[1]=34

list[2]=46

In particular, I'm wondering if Boost::Tokenizer does this. Although I couldn't find any examples that didn't use strings.

The C++ String Toolkit Library (StrTk) has the following solution to your problem:

#include <string>
#include <deque>
#include "strtk.hpp"

int main()
{ 
   {
      std::string data = "12 34 46";
      std::deque<int> int_list;
      strtk::parse(data," ",int_list);
   }

   {
      std::string data = "12.12,34.34|46.46 58.58";
      std::deque<double> double_list;
      strtk::parse(data," ,|",double_list);
   }

   return 0;
}

Note: The parsing process is EXTREMELY fast and efficient, putting stdlib and boost based solutions to shame.
