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.

How do you declare local and global variables in pseudo code?
Pseudocode is not a programming language (it's specifically intended for human interpretation), so there is no need to declare variables, you simply define them as and when you require them. For instance: Let x = 42 Let y = x * 2
Is a global variable a non-local variable?
True, a variable cannot be both global and local. But if a global and a local variable share the same name, the local one will hide the global.
What is a local variable and What statements are able to access a local variable?
A local variable is a variable that can only be called on by the module. Where as a global variable can be called upon by any module. Only statements made inside the same module can call on a local variable.
Why all variables are declared with in the function?
It is not necessary to to declare variables inside the function in C. If you declare a variable inside a function, the variable becomes local for the function and another variable of same name can be declared in any other function, but you can not use the variable declared in other function. When you declare any variable outside the function body then the variable becomes global and can be used in any function of the program. Note: errno is an example for a variable declared outside any function.
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.

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.
How you can declare local variable?
variable exit within a function and curly braces is local variable int main() { int x; }
What is the difference between declaring static variable as local and global?
There are two ways to declare varibles. 1. Locally 2. Globally When you declare a variable locally in any function that means it is only accessible by that function. When you declare a variable globally so it is accessible by all the functions in the program. Declaring variables with static keyword means you are setting its value null.

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 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.

Different between local and global?
The scope or the life span. The life span is from the birth (allocation) to death (deallocation). The life span of a global variable starts when the application is invoked. It dies when the application terminated. During the execution of the application , this global variable is available to any program unit within that application. The life span of a local variable, well, only locally. "Local" means a component, a method (subroutine), or even within a bracket ({} or BEGIN-END) of a statement. Outside of that block of codes, that local variable does not exist, hence cannot be accessed or referenced. Also, the same name of that local variable may be declared again in another local area without conflict, nor memory of the previous one. For languages similar to C: for (int i = 0; i < 100; i++) { // i can be referenced within { }, and within the for() control itself } for (int i = -1; i > -200; i--) { // this i is different from the i in the previous for-loop } Some computer language would allow you to declare a local variable with the same name as the global one (for example, there are global::X and local::X, but the code only refer as X). Most of the computer language would replace X with local::X at compile time, some would replace it with global::X) Some languages may not have the notion of local variables, everything is global, and some would not have the notion of global variable, but would provide a mean to act like one.
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.
