I like to specialize in the knowledge I love and the joy of completing the project come on. When your strength can't meet your goals, calm down and learn! Pointer Basic concept of pointer Function of pointer: memory can be accessed indirectly through pointer The memory number starts from 0 and is generally represented by hexadecimal d ...

Understanding the asynchronous notification I/O model Synchronous and asynchronous The key of synchronization is the call and return time of function, as well as the start and completion time of data transmission. Data transmission starts at the moment when the send function is called, and the data transmission is completed at the moment ...

Monotone stack Is it time to use monotone stack We must remember that the data structure must assist us in solving problems, and must be optimized in the way of violent solution (in fact, space for time) The monotone stack must meet the first in first out feature when processing data, just as we must meet the first in first out feature w ...

unique_ptr unique_ptr is a move only type (move only type, std::mutex, etc.). Combine the factory mode to see its basic usage, and give priority to std::make_unique : (for the factory mode, see my notes: https://zhuanlan.zhihu.com/p/423725151) #include <iostream> #include <memory> class Animal { public: virtual void Print( ...
