Definido no cabeçalho <tuple>
template<class... Types> tuple<VTypes...> make_tuple( Types&&... args);		(desde C++11)

Creates a tuple object, deducing the target type from the types of arguments. The deduced types are std::decay<Ti>::type (transformed as if passed to a function by value) unless application of std::decay results in std::reference_wrapper<X> for some type X, in which case the deduced type is is X&.

Valor de retorno

A std::tuple object containing the given values.

Exemplo

#include <iostream>#include <tuple>#include <functional>   int main(){auto t1 = std::make_tuple(10, "Test", 3.14);std::cout<<"The value of t1 is "<<"("<< std::get<0>(t1)<<", "<< std::get<1>(t1)<<", "<< std::get<2>(t1)<<")\n";   int n =1;auto t2 = std::make_tuple(std::ref(n), n); n =7;std::cout<<"The value of t2 is "<<"("<< std::get<0>(t2)<<", "<< std::get<1>(t2)<<")\n";}

Saída:

The value of t1 is (10, Test, 3.14) The value of t2 is (7, 1)
