"Heaven and Earth Xuan Huang, the Universe primitive", First has the world, the rear has the ancient and modern.Variables are the same, with the scope of the variable (where it exists), and then the lifetime of the variable (the time it exists)."How variables are stored"The first variable is actually stored in two regions: Static storage: Refers to how the system allocates a fixed amount of storage space in the program run interval.

is completely invisible. The main difference between it and the OnPause () method is that, for example,The new activity that starts is a dialog-style activity, then the OnPause () method is executed, while the OnStop ()method does not execute.6. OnDestroy ()This method is called before the activity is destroyed, and then the state of the activity becomes the destroy state.7. Onrestart ()This method is called before the activity is changed from the stopped state to the running state, i.e. the ac

What is the relationship between survival and scope? Let's explain the lifetime first.The memory space corresponding to a process contains five different data zones.Stack, heap, BSS segment, data segment, and code segment are arranged in the ascending order of memory.STACK: stores local objects temporarily created by the program. Generally, the executable file generated by VC ++ 6.0 is only 1 MIB of stacks.Heap: stores the memory segments dynamically

Unity uses classes that inherit from the Lifetimemanager base class to control how the reference to the object instance is stored and how the container destroys the instances, that is, unity is managing the creation and destruction of objects based on the specific lifetime manager class. Currently there are two lifetime manager classes available for us to use directly, and of course you can implement your

People seem to use this concept inadvertently. I often see it used as a lifetime or definition space, for example, "when this variable is out of scope, the corresponding memory space will be released "

Local variablesScope: A variable defined within a function that is scoped to the body of the function.Lifetime: The program executes to this function to assign a memory unit to a local variable, and the storage unit that the local variable occupies is freed after the function executesGlobal variablesVariables defined outside the body of the function are global variables that can be used by all other functions in this file.Scope: All files. In a CPP-defined global variable used in another CPP, th

. Static local variables always exist, that is, their lifetime is the whole sourceProgram.(2) Although the lifetime of the static local variable is the entire source program, its scope is still the same as that of the automatic variable, that is, the variable can only be used within the function that defines the variable. After exiting the function, although the variable still exists, it cannot be used.(3)

"C Program Design" rectification version 4th for the lifetime scope of the auto variable is described, including memory management and release, stating that "after the function is finished, automatically release the memory units occupied by the automatic variable"After the function is finished, the automatic variable is freed, even if it is returned as a pointer, and the pointer address does not change when returned, but any read operation flushes the
