What is Global variables in vb6?
Global variables are accessible through your project. Different classes, modules, and interfaces can access a variable if it is global. A Global Variable can simply be declared by putting the word Public in front of the variable. Here is an example. Public V As String Now anything in your whole entire project can access the variable V.
If the variable flag can only be declared once in the program it was declared as what type of variable?
It's a global variable.
How do you access global variable from within the main function when the local variable is of the same name?
When you acess a global variable inside main function you must use the same name, because the variable declared as global can be accessed by any function/procedure on the class where it was defined.
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.

Why static variables in a function have global extent?
A variable declared static outside of a function has a scope the of the source file only. It is not a global variable. A variable declared outside of a function and without the static qualifier would be a global variable.
What is the difference between a static variable a global variable and a local variable?
A static variable is a variable allocated in static storage. A local variable is a variable declared inside a function. A global variable is a variable declared outside of any class or function. Note that local variables and global variables can both be allocated in static storage.
What is the difference between global variable and extern variable?
Global variables are non-local variables. That is, variables that are not defined in a function or class. They are globally accessible to all code in the same translation unit. External variables are global variables that have external linkage; they are accessible across translation units.
How can you declare global and local variable in pseudocode?
A local variable is a variable declared inside a construct, such as a class or function, while a global variable is a variable declared outside of any construct.
Which is the keyword used to access the variable declared as global variable in another file?
To be able to access a variable declared in one file/class from another file/class you need to declare that variable as "public". Doing this is a very bad coding practice because exposing a variable of a class to be available publicly to other classes is totally against the Java object oriented concepts of Encapsulation and Data hiding. So, preferably you shouldn't be doing this. However, a better way to do this is, declare the variable as private and have public accessor methods through which you can access this variable. This will ensure that your data is protected even if it is available outside the class
How are global variable different from local variable in Visual BASIC?
A global variable is available for use throughout the program. It is normally declared outside any procedure. A local variable is only available for use in the procedure it was declared in. Most variables are local, but there will be occasions when you want different procedures to be able to use the same variable. This is when you use a global variable.
What are global variable?
Variables that are declared globally outside every program are called global variables.
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.
