Chapter8_math instance, the Add method, which is declared as PUBILC in the parent class, is clearly overridden in the subclass.Of course, when we were wondering about "Case 3", we might have overlooked that "case 3" was created as a math instance, so from the compilation to the heap is a typical parent class, so this is not the overriding operation at all.Now, there is a key point to the static method problem of the static modification,The sub method, which is now declared static, is obviously

- 设置关注变量 - 18.9 detection system 18.9.1 using UID as selection criteria if (current->uid! = 7777) { / old algorithm / Else { / New Algorithm / } 18.9.2 Using condition variables You can use conditional variables if your code is not process-independent, or if you want to have a mechanism that can be used for all situations to control an attribute. This is easier than using UID, just to create a global variable as a conditional selector

I browsed the books launched in 2005 only in 2010. I did not work hard in these years. If it weren't for the "first-line architect Practice Guide", I would continue to ignore this book every time I stood in front of the shelf of Luming bookstore. To be honest, if I read this book in 2005, it will be a great improvement for myself. MQ, COM +, authentication, authorization, and configuration. At that time, I
