make_tuple Function

Makes a tuple from element values.

template<class T1, class T2, ..., class TN>
    tuple<V1, V2, ..., VN>
    make_tuple(const T1& t1, const T2& t2, ..., const TN& tN);

TN

The type of the Nth function parameter.

tN

The value of the Nth function parameter.

The template function returns tuple<V1, V2, ..., VN>(t1, t2, ..., tN), where each type Vi is X& when the corresponding type Ti is cv reference_wrapper<X> and Ti otherwise.
