deductiongu...forstd::pair(3) C++ Standard Libarydeductiongu...forstd::pair(3)

NAME
       deductionguidesforstd::pair - deductionguidesforstd::pair

Synopsis
	  Defined in header <utility>
	  template<class T1, class T2>	 (since	C++17)
	  pair(T1, T2) -> pair<T1, T2>;

	  One  deduction  guide	 is  provided for std::pair to account for the
       edge cases missed
	  by the implicit deduction guides, in particular, non-copyable	 argu-
       ments and array to
	  pointer conversion.

Example
       // Run this code

	#include <utility>

	int main()
	{
	    int	a[2], b[3];
	    std::pair  p{a,  b};  //  explicit deduction guide is used in this
       case
	}
