专门性
The standard library provides a specialization of std::divides when T is not specified, which leaves the parameter types and return type to be deduced. divides<void> function object implementing x / y deducing argument and return types (class template specialization) | divides<void> | function object implementing x / y deducing argument and return types (class template specialization) | (since C++14) |
|---|---|---|---|
divides<void> | function object implementing x / y deducing argument and return types (class template specialization) |
