Hi Angelo,

std::cout << "var: " <<  add << std::endl;
     std::cout << "vm: " <<  vm["add"].as<int>() << std::endl;
     po::notify(vm);
return 1;
}
Compiling and running:
$ g++ program_options.cpp -lboost_program_options
$ ./a.out --add 4
var: 5
vm: 4
Why the value of the variable "add" is not receiving 4?
Because 'add' is only assigned when you call po::notify, and your program prints the value
of 'add' before calling po::notify
