static local variable

The static function of C ++ has two usage methods: static in process-oriented programming and static in object-oriented programming. The former applies to common variables and functions, and does not involve classes. The latter mainly describes the

ArticleDirectory (1) Auto (2) Register (3) static (4) const (5) Volatile (6) extern (1) Auto This keyword is used to declare that the lifetime of a variable is automatic, and variables not defined in any class, structure,

1: What is block body, what is the form, and when is it used?A) block is a C-level syntax and a feature of the runtime, similar to a function (function pointer) in standard C, which supports blocks very well starting with ios4.0. b) Its form is as

The visibility (i.e. scope) and lifetime of a variable are both distinct and related.A variable is not visible at some point in the program, but life can exist, such as the visibility of a local static variable in its function, outside the function

Usually see STRRCHR This function, people naturally want to ask the library is there strrstr this function???The answer is: No.But we can implement a STRRSTR function, its function is to find the last occurrence of the substring, if the call will

C Language Program after compiling the link to form a binary image file consists of stacks, heaps, data segments, code snippets, wherein the data segment is divided into: read-only data segment, has initialized the read and write data segments,

The In-memory stack area is at a relatively high address in the direction of the growth of the address, the stack address is growing downward, the stack is allocated local variable space, the heap area is an upward increase in the memory allocated

I. Variable declaration format: Storage Type modifier data type variable name; 2. function declaration format: storage type return type function name (parameter list) {} Storage types: 1. Auto : Only the storage type of [variable] can be identified.

1. static variable The type description of static variables is static. Static variables belong to static storage, but not necessarily static variables. For example, an external variable is a static storage method, but not necessarily a static

PHP static member variables and non-static member variables, PHP static data members can be divided into static variables, non-static variables, two kinds .Static member: A member in a static class joins the static modifier, which is a statically

Static variables can be static global variables. If unset is not called, the static variables will always exist until the program exits and is managed by Zend memory to release them. it can be static local variables: as defined in the function,

InC LanguageStatic (static) and extern (external) keywords are often used, but improper use mayProgramThe design is troublesome. Here we will introduce it. 1. Declare or define variables 1. Local variables: Static variables defined in the
