Smart Home System Architecture Based on the Internet of Things operating system hellm Smart Home is a branch application of IOT and a huge IT market space widely recognized. There are already many products or solutions for smart families on the market. However, unlike the mobile Internet, smart families have not yet fo

; setnextptr (ptrb ); Delete ptrb; This will cause a problem, because these pointers are connected into a loop, no matter from which point the deletion will cause a pointer to be deleted more than twice, which will cause the program to throw an exception. Of course, there are also some ways to solve this problem, but it is not difficult for C ++ programmers to develop a good habit, the difficulty is that sometimes this will bring you into a logical chaos, add unnecessary troubles, and sometimes

C + + Smart pointers First, Introduction Since the C + + language does not have an automatic memory recycling mechanism, the programmer will manually delete each new memory. The programmer forgets the delete, the process is too complex, resulting in no delete, the exception causes the program to exit prematurely, and the absence of a delete is not uncommon. The use of smart pointers can effectively allevi

To address the problem of C + + memory leaks, C++11 introduced smart pointers (smart Pointer).The principle of smart pointers is to accept a well-applied memory address, construct a smart pointer object stored on the stack, there is an important principle in C + +, at the end of the function (whether it is normal retur

a class to add a layer of packaging, the simplest is like this: "Class My_intptr{Publicint* m_p;My_intptr (int* p) {m_p = P;}~my_intptr () {delete m_p;}};............My_intptr Pi (new int);* (pi.m_p) = 10;............"Here we can safely use my_intptr without worrying about memory leaks: Once the PI variable is destroyed, we know that the memory block pointed to by PI.P is bound to be freed. But it would be too much trouble to access its members every time you use MY_INTPTR. To do this, you can

With the constant improvement of people's pursuit of quality of life, the requirements for living and living life are even higher. With the gradual development of smart life, people began to pursue a convenient and comfortable living environment, so smart home has become the target of many consumers. Modern people pay more and more attention to personalized life, especially as we join the 80 s after purchas

Today on the Internet to see an article on the smart pointer, feel very good, so reproduced to learn.　　Source: https://www.cnblogs.com/lanxuezaipiao/p/4132096.htmlGuideRecently in the sixth edition of "C + + Primer Plus", this is indeed a good book, where the chapter on smart pointers is very clear, a solution to many of my previous confusion. In the C + + interview process, many interviewers like to ask qu

In Gamebryo, you can use smart pointers to achieve semi-automatic reference counting. This is implemented through the NiPointer. This template class overload the operator so that its instance is represented as a standard pointer. However, The smart pointer automatically increases and reduces the reference count of the object to which it points, so that the application does not directly call the reference co

First, IntroductionSince the C + + language does not have an automatic memory recycling mechanism, the programmer will manually delete each new memory.

normal pointer has no constructors and destructors, so we have to write a class to add a layer of packaging, the simplest of which is like this: " Class My_intptr{Publicint* m_p; My_intptr (int* p) {m_p = P;}~my_intptr () {delete m_p;}}; ............ My_intptr Pi (new int);* (pi.m_p) = 10; ............"Here we can safely use my_intptr without worrying about memory leaks: Once PI is destroyed, we know that the block of memory that PI.P points to is bound to be released." But it would be too much

Intelligent home, that is automation, sometimes called smart-home. Smart home at the earliest when the internet was mentioned and the product appeared at the time is about 2013 years, then LU continued to appear a lot of "intelligent technology", "artificial Intelligence" at the beginning of the home, but many smart home products appear instead of making consumer
