deductionguidesforstd::pair(3) | C++ Standard Libary | deductionguidesforstd::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 arguments 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
}
