struct S { var a = VArray<Int32, $2>(item: 0) var b = VArray<Int32, $0>(item: 0) } 注意 C 语言中允许结构体的最后一个字段为未指明长度的数组类型,该数组被称为柔性数组(flexible array),仓颉不支持包含柔性数组的结构体的映射。字符...
Convert uint64_t to byte array portably and optimally in Clang 如果要将uint64_t转换为uint8_t[8](小尾数)。在小端架构上,您只能执行难看的reinterpret_cast<>或memcpy(),例如: 123 void from_memcpy(const std::uint64_t &x, uint8_t* bytes) { std::memcpy(bytes, &x, sizeof(x)); } ...

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 from the integer value) and update the definition of new and delete to cast back to the integer type. You don't need to use an enum for this; a ...
