How do we tuple initialize a class or structure?

Consider the following structure: struct X { int a; double b; // ... }; Here we could initialise with a std::tuple<int, double>. To achieve this we simply define a constructor that accepts the required tuple: #include<tuple> struct X { int a; double b; X::X (std::tuple<int, double>& t): a {std::get<0>(t)}, b {std::get<1>(t)} {} // ... }; Note that any constructor that has one argument is known as a conversion constructor, in this case converting from tuple to X. It is usually a good idea to declare such constructors explicit, particularly if you also provide the complementary conversion operator (from X to tuple). #include<tuple> struct X { int a; double b; explicit X::X (const std::tuple<int, double>& t): a {std::get<0>(t)}, b {std::get<1>(t)} {} operator std::tuple<int, double> (void) const {return std::make_tuple (a, b);} // ... };
