Hi! Jim, Could you please tell me why this code is not working:
#include <iostream> #include <boost/any.hpp> using namespace boost; int main() {
any holdsanything ; holdsanything = 9; std::cout<<holdsanything<<endl; holdsanything = std::string("hello"); std::cout<<holdsanything<<endl; return 0; }
Hi, Raj You didn't specify what problems you were having. Am I correct in assuming you get a compiler error on the std::cout lines? If so, then the problem is that class 'any' does not have an extraction operator defined. If you change the lines to: std::cout << any_cast<int>(holdsanything)<<std::endl; and std::cout << any_cast<const char *>(holdsanything) << std::endl; it should work properly. -- Jim
