首先将参数1,2,3打包,打包前1,2,3明显属于python数据类型中的integer,pack后就变成了C结构的二进制串,转成 python的string类型来显示就是 '\x01\x00\x00\x00\x02\x00\x03'。由于本机是小端('little- endian',关于大端和小端的区别请参照这里,故而高位放在低地址段。i 代表C struct中的int类型,故而本机...

You may also inherit from a POD struct. Unlike in C++, other programming languages might not support multiple inheritance or inheriting from a type that isn’t a class. Internalizing such subtleties is critical to a successful migration. Pay attention to the tiny-yet-crucial details. Give t...

The move constructor, on the other hand, can just copy the pointer and then set the pointer in the source to null. It is okay to "nullify" the source object in this manner, because the client has no way of inspecting the object again. I hope this example got the main point across....
YAML uses space indentation, which is familiar territory for Python developers. JavaScript developers love JSON because it is a subset of JavaScript and can be directly interpreted and written inside JavaScript, along with using a shorthand way to declare JSON, requiring no double quotes in keys wh...
