[Boost-users] Concatenating int value to string ..??

2 Nov 2013

      All,

I wish to have string (combination of string value and int value) which
increments until 100. The code is as below -

---
#include <iostream>
#include <cstdlib>
#include <string>
#include <boost/lexical_cast.hpp>

using namespace std;

int main() {
        std::string TID = "Apple";
        int TagID = 01, Value = 000 /* 100 IDs*/;
        std::string TagName, TagInitial, TagUId;
        TagName = TID + boost::lexical_cast<std::string>(TagID); // Should
be as -> Apple01
        TagInitial = TagName + boost::lexical_cast<std::string>(Value); //
Should be as -> Apple01000
        int i = boost::lexical_cast<int>(TagInitial) + 1; // Should be as
-> Apple01001
        TagUId = boost::lexical_cast<std::string>(i);
        std::cout << "Tag ID .." << TagUId << endl;
}

I get below error message -

--
terminate called after throwing an instance of
'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::bad_lexical_cast>
...
'
  what():  bad lexical cast: source type value could not be interpreted as
target
Aborted (core dumped)
--
Any clue?

~ Thanks!!
