3)find_if搜索谓词p对其返回true的元素。 5)find_if_not搜索谓词q对其返回false的元素。 2,4,6)同(1,3,5),但按照policy执行。 这些重载只有在满足以下所有条件时才会参与重载决议: std::is_execution_policy_v<std::decay_t<ExecutionPolicy>>是true。

阅读cppreference.com,我注意到 ranges::find_last_if 不返回迭代器,但 ranges::find_if 却返回迭代器。我想知道这个决定是否有充分的理由? 显然,正确的用法是使用 ranges::find_if 并反转范围: const auto it = std::ranges::find_if(data | std::views::reverse, func); 也就是说, ranges::find...
