为什么在 C 17 中添加了 std::reduce? 我正在寻找对std::reduce的“返回值”描述的含义的彻底解释,根据 cppreference.com,它是: 也许在我正确理解本节之后,我可以更好地确定何时应该选择std::reduce而不是std::accumulate。 由于您要求进行彻底的解释,而先前的答案仅涵盖基础知识,因此我冒昧地添加更详尽的解释。
参考: std::reduce - cppreference.com及: 迦非喵:std::accumulate简单测试有: CMakeLists.txt cmake_minimum_required(VERSION 3.15) project ( testprj ) set ( PRJ_COMPILE_FEATURES ) list ( APPEND PRJ_C…
