#includeThis example shows how to create a new String_var object and assign a string to it. The value of the string can be accessed using the `in()` method. The example also demonstrates how to release the String_var object and shutdown the ORB. The `example.hh` file is part of the CORBA package library and contains the IDL (Interface Definition Language) definition for the Example module, which defines the String_var datatype.#include #include #include "example.hh" using namespace std; int main(int argc, char* argv[]) { // Initialize the ORB CORBA::ORB_var orb = CORBA::ORB_init(argc, argv); // Create a new String_var object Example::String_var str_var = new CORBA::String_var("Hello, world!"); // Print the value of the String_var object cout << str_var.in() << endl; // Release the String_var object str_var = CORBA::String_var(); // Shutdown the ORB orb->shutdown(); orb->destroy(); return 0; }
