c++ - Writing a series of std::conditional with the same condition -


is there more compact way write following?

typedef typename std::conditional< condition, type_a1, type_b1 > type_c1; typedef typename std::conditional< condition, type_a2, type_b2 > type_c2; typedef typename std::conditional< condition, type_a3, type_b3 > type_c3; ...

where condition same, , type_ax, type_bx, type_cx different lines different.

template<class a, class b> using select = std::conditional_t<condition, a, b>;  using c1 = select<a1, b1>; // or typedef if syntax // etc.
