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.
