Comparison between several smart pointers in C ++, smart pointersWhen designing these smart pointers, a key issue is the control of ownership. If you compare the object pointed to by the pointer to a TV, the pointer is the audience. When the first person needs to watch TV, he needs to turn it on. When no one needs to watch TV, he must make sure to turn off the TV

In C + +, programmers can manipulate memory directly, adding a lot of flexibility to programming. But flexibility comes at a cost, and programmers have to be responsible for releasing the memory they're applying for, or there's a memory leak. Smart pointers exist to solve this problem. It has no essential difference from other pointers, and the main purpose is to avoid the problem of hanging pointers and memory leaks. Here, I use the object's app coun
Smart pointers are a way of using the RAII mechanism (explained later) in C + + to manage pointers through objects.In C + +, dynamic memory needs to be maintained by ourselves, we must release it manually before the function scope or program exits abnormally , otherwise it will cause a memory leak.For example: When we use pointer variables to create an object, we need to manually delete itString * pstr = new string ("Hello world!"); .... delete Pstr;I

Unlike Java and C #, C ++ does not have a garbage collection mechanism, but it provides a powerful and flexible management mechanism that allows developers to avoid memory leaks. You can use new to obtain the memory or create objects, and delete must be used to release them, so as to avoid Memory leakage. At the same time, the allocation and usage can be encapsulated with cla
