No. A static member variable is local to the class in which it is declared (much like a global, but scoped to the class) and is accessible to all instances of the class. Since it does not belong to any one instance of the class, it cannot be accessed via the this pointer, as you can with non-static members. Implicitly accessing the variable is the same as explicitly accessing it via
Note that it is possible to access a static member variable from outside the class by providing an accessor (getter) for it within the class. The accessor should be static as well, but needn't be, but it should return by value, otherwise it is no better than a global.

Why use static variable in programming language?
For C programming, the use of a static variable has two uses: One reason is to hide the variable from other modules. The scope of the static variable is limited to the compilation unit that it is described in. The second use of a static variable is to keep the value of the variable intact through the entire program execution unit.
When do we use an address operator in c'?
In C we use & operator while giving address of some variable to some pointer variable. & operator is also used in scanf().
How do you create static variables in PHP?
Use the "static" keyword to declare a static variable within a function like shown below. <?php function fun() { static $variable; static $another_variable = ''; } ?>
what is the difference between final and static keywords?
static: we can use the keyword static either to method or to a variable. when we declare to a method,(eg: public static void main(String args[]),we can use this method without any object. when we use to a variable,there will be only one instance of that variable irrespective of how many objects that get created of that class. Final: Usage of final to method or to a variable makes them as constant. It's value cannot be changed...

How can a PHP static be initialized?
PHP static can only be initialized using a literal or constant. You can not use an expression. You can initialize it to an integer but you may not to another variable.
Describe about storage allocation and scope of global extern static local and register variables?
Global Varible: The variable which is declared as "Global" one : having the preveleges to use and access that variable in any class and object( means any where in the program) just like PUBLIC keyword in OOPS concepts. Static Variable : If we declare a variable as Static , then it wont have the permission to access that variable through out the program and u have to use it inside the class or object which u declared itself.

In pointers what is the use of pointer variable?
Pointer is a variable that stores the address of another variable . So pointer basically stores the address of another variable and size of pointer can be evaluated by using sizeof operator.
Static method can use only static variable why?
A static method is a method that is a class method and is not attached to the object of that class. So if we use a non static variable of the class, it would most probably not have been initialized because no object could have been created for the class. Hence it would throw a null pointer exception. To avoid such an ambiguity, there is a restriction that static methods can use only static variables. This is to ensure that class methods can access only class variables both of which would get initialized simultaneously.
Which operator is allow to access hidden global variable in c plus plus?
A hidden global variable must be one that has its scope blocked by a local variable of the same name. To access the hidden variable, use the scope resolution operator ::, such as is ::variable_name. If there is another reason for the hidden status, please clarify and restate the question.
