使用std::iota函数,您可以提供一个起始值和一个结束值,函数会自动填充数组的元素。例如: std::array<int, 5> arr; std::iota(arr.begin(), arr.end(), 1); //从1开始递增初始化数组
问使用std::for_each和std::view::iota的并行循环EN当给定一个容器范围,我们通常需要对其中的每个...
问如何在std::结对中使用std::iota?ENC++中函数指针的用途非常广泛,例如回调函数,接口类的设计等,...
(顺便说一下,不要这样写生成器:有一个更好的特定生成器:std::iota)。 是的,通过lambda捕获的变量默认是const的,如果你想在lambda体中更改它们,你需要明确地使它们可变: std::generate_n(std::back_inserter(srcVec),10,[init]()mutable{returninit++;}); ...
