Synopsis

One deduction_guide is provided for std::array to provide an equivalent of std::experimental::make_array for construction of std::array from a variadic parameter pack. The program is ill-formed if (std::is_same_v<T, U> && …) is not true

Example

  #include <array>   int main()   {       int const x = 10;       std::array a{1, 2, 3, 5, x}; // OK, creates std::array<int, 5>

  // std::array b{1, 2u}; // Error, all arguments must have same type   }
