subclass's destructor?Because the premise of polymorphism is virtual function.Under normal circumstances, the destructor of a class should be written as a virtual function, which, if forgotten, could cause a memory leak.(2) A space for an array is applied, but only the space of the first element is releasedclassnewclass[5];delete pA;Not all of these situations can lead to memory leaks, and if class is a built-in type, such as int, char, there is no p

What is the memory leak in the program? We have written many programs with the keyword Free (). For example, I am in this post about some of the important operations of the list (Important operations on a Linked list) to delete the entire list of this function, the code snippet is as follows:struct node * deletelist (struct node * head) { struct node * temp; while (Head! = NULL) { = head; = Head , next; Free (t

Android WebView Memories Leak WebView Memory leaksIn this development process, you need to use the WebView to display some interfaces, but the loaded page if there are many pictures will find the memory consumption soared, and after exiting the interface, even in the activity of the webview containing the Destroy () method, Use Webview.destroy (), webview=null, or no effect on memory for recycling.

Visual Leak Detector (VLD). The downloaded version is 1.9d. It supports vc6, vc7 (2003), and vc8 (2005). It is open-source and can be compiled based on the source code, 64-bit machines can compile 64-bit machines by themselves. However, in my machine (64-bit CPU, 64-bit windows7), 74-bit is not compiled separately. VLD is only valid for the debug version of the program and does not work for the release version. Therefore, you can use VLD in a release
