Let’s understand symmetric matrices better with a concrete example. Consider the following (3 \times 3) square matrix: 我们可以清晰地看到,该矩阵的元素关于主对角线对称。这种对称性质在计算机科学、物理学、工程学等多个领域都有广泛应用。 It’s evident that the elements of this matrix are symmetric...
enum class my_type : size_t {}; Then, change your definition of placement new and delete to use this type as the second argument instead of size_t. You'll also need to update the calls to placement new to pass the new type (for example, by using static_cast<my_type> to convert...
