The objects of a class can be passed as arguments to member functions as well as nonmember functions either by value or by reference. When an object is passed by value, a copy of the actual object is created inside the function. This copy is destroyed wh

questions on C++ classes and objects includes MCQ questions about different ways of specifying a class and creating objects, defining and nesting of member function, private, static and constant member function. It also includes static data members and methods of using objects as function arguments....
Passing R6 objects as arguments to C++ functions is also straight forward by treating them as environments: #include<Rcpp.h> using namespace Rcpp; // [[Rcpp::export]] void give_shovel(Environment &person){ String item = "shovel"; Function give_i = person["give_item"]; give_i(item)...
This is really nit-picking and some would even argue it's better to know when you're performing a conversion. For example, CStrings can get you in trouble with functions that use C-style variable arguments (varargs), such as printf:Copy ...
Person(std::string n, int a) { // define a constructor for Person class that takes a string and an integer as arguments name = n; // set the value of 'name' data member to the argument passed in age = a; // set the value of 'age' data member to the argument passed in ...
