Another useful member that functions in the tuples classes is tie(), which is used to unpack a tuple into individual objects or create a tuple of lvalue references. Also, we have the ignore helper class in tuples, a placeholder to skip an element when unpacking a tuple is using tie(). Let's see the use of tie() and ignore in the following block of code:
/* tuples_2.cpp */ #include <tuple> #include <iostream> using namespace std; auto main() -> int { cout << "[tuples_2.cpp]" << endl; // Initializing two Tuples tuple<int, string, bool> t1(1, "Robert", true); auto t2 = make_tuple(2, "Anna", false); int i; string s; bool b; // Unpacking t1 Tuples tie(i, s, b) = t1; cout << "tie(i, s, b) = t1" << endl; cout << "i = " << ...
