Most of the time the compiler must deal withdynamicvariables, i.e. variables that are initialized and destroyed at runtime: local (block-scope) variables, function arguments, non-static class members, etc. The compiler has little chance to initialize such variables before execution starts: How i...

Static data refers to data that all objects of the class share and that you can modify after creation.
A static member function cannot access the non static members of the class or base class class X{ public: int b; static int a; enum mode{a1,a2,a3}; static int inc() { return b;//this will give an error } X(){}; }; Static data members of class have extern linkage, they ca...

Like static data members, you may access a static member functionf()of a classAwithout using an object of classA. A static member function does not have athispointer. The following example demonstrates this: #include <iostream> using namespace std; struct X { private: int i; static int ...
class SomeClass { static function methodName (identifier1 = value1, identifier2 = value2, ... identifiern = valuen) { } } As with instance methods, access-control modifiers can control the accessibility of static methods in a program. The access-control modifiers available for static-methods...
@SuppressWarnings("static-access")是什么意思呀?相关知识点: 试题来源: 解析 指示应该在注释元素(以及包含在该注释元素中的所有程序元素)中取消显示指定的编译器警告.注意,在给定元素中取消显示的警告集是所有包含元素中取消显示的警告的超集.例如,如果注释一个类来取消显示某个警告,同时注释一个方法来取消显示另一...
