what is the difference between local variable and global variable?
76271
Global variables are declared outside any function, and they can be accessed (used) on any function in the program. Local variables are declared inside a function, and can be used only inside that function. It is possible to have local variables with the same name in different functions.

If static variables are declared outside of all functions it will have global scope or it is declared within a function it will have scope within a function and it will retain until the life of program.

Static variables: means that they will die with the program itself, this means that the memory will be allocated & never will be released implicitly. Global: these variables can be accessed from anywhere. Local: these variables can be accessed inside their scopes only.

If a variable is global, you can access it in any compilation unit (commonly called source file, module etc.) If a variable is defined globally, there should be a way to tell compiler about possible global variables (or functions) that we may encounter. Keyword extern is present exactly for the same reason.

JavaScript variables have only two scopes. Global Variables − A global variable has a global scope which means it can be defined anywhere in your JavaScript code. Local Variables − A local variable will be visible only within a function where it is defined. Function parameters are always local to that function.

A local variable is the variable you declare in a function. Its lifespan is on that Function only. A member variable is the variable you declare in a class definition. Its lifespan is inside that class only.It is Global Variable.It can be access by any function inside that same class.

Global variables are variables which are defined outside the function. ... ﻿Static local variables: Variables declared as static inside a function are statically allocated, thereby keeping their memory cell throughout all program execution, while also having the same scope of visibility as automatic local variables.

Global Variables In Labview. Global variables are built-in LabVIEW objects. You can use variables to access and pass data among several VIs that run simultaneously. A local variable shares data within a VI; a global variable also shares data, but it shares data with multiple VIs.
