dangling reference

The article is a bit long, the process of writing is very rewarding, but the process of reading is not necessarily a harvest, cautious intoThe crash problem caused by the "abstract" dangling pointer (dangling pointer) is often encountered during the

ARCThe compile time feature of the automatic memory management of the ARC Apple version. It represents the automatic reference count (Automatic Reference counting). That is, for an object, memory is freed only if the reference count is 0.Strong

Java parameter mode-value passing or reference passingArguments are passed by value instead of by reference. The Java application has only one parameter passing mechanism that is passed by value. It is written to expose a pervasive myth that Java

An important feature of the Java language is the introduction of an automatic memory management mechanism that allows developers to manage memory in their applications without their own. C + + developers need to explicitly allocate and free memory

An important feature of the Java language is the introduction of an automatic memory management mechanism, so that developers do not have to manage the memory in the application on their own. C/C ++ developers need to use functions such as

Auto Reference Count (Automatic Reference counting, ARC)Garbage collector:Starting with Mac OS X 10.8, the " Garbage collector " (Gargae collector) has officially been deprecated.Each object has a counter that indicates how many things are currently

The importance of proper memory management C and C + + programs that have memory errors can cause various problems. If they leak memory, the running speed slows down and eventually stops running, and if memory is overwritten, it becomes very

Smart Pointers-what, why, which? What are they? Smart pointers are objects that look and feel like pointers, but are smarter. What does this mean? To look and feel like pointers, smart pointers need to have the same interface that pointers do: they

IntroductionThe Objective-c language uses reference counts to manage memory, that is, each object has a counter that can be incremented or decremented. If you want to keep an object alive, increment its reference count, and after it is exhausted, it

Arguments are passed by value instead of by reference. The Java application has only one parameter passing mechanism that is passed by value.Objects are never passed in a Java application, and only object references are passed. Therefore, the object
