回答 1. std::length_error异常通常发生的情况 std::length_error 是C++标准库中的一个异常类型,用于表示尝试分配的内存大小超出了容器所能容纳的最大值。这种异常通常在使用STL容器(如std::vector)时发生,当向容器请求的空间超过了其最大容量限制时,就会抛出此异常。 2. 导致std::vector抛出std::length_error...

C++网格类(std::vector of cells)自定义大小调整函数导致分割错误。 在C++中,网格类通常用于表示二维或三维的网格结构,其中每个单元格存储了特定的数据。使用std::vector来存储单元格可以方便地进行动态大小调整。 然而,当我们自定义网格类的大小调整函数时,可能会出现分割错误。这种...
