The Scope of the variable determines the accessibility of the variable to a particular part of the application. Variables can be declared within the class, method, and code block of a loop, condition, etc. There are three types of scopes in C#.
A variable scope refers to the availability of variables in certain parts of the code. In C#, a variable has three types of scope: Class Level Scope Method Level Scope Block Level Scope C# Class Level Variable Scope In C#, when we declare a variable inside a class, the variable can be ...

An object is recognized by the computer by either its identifier or name. The object may be a variable of basic type or a function, a structure, or a union. The macro names and macro variables do not figure in the scope because macros are replaced by the
Variable scope refers to a variable's visibility to the other code in your application. A locally scoped variable is only accessible inside of the code block in which it's defined. If you attempt to access the variable outside of the code block, you'll get a compiler error....
In z/OS® Debugger, an object can be a variable or function and is also used to refer to line numbers.Note: The use of an object here is not to be confused with a C++ object. Any reference to C++ will be qualified as such....

The scope of a variable inpythonis that part of the code where it is visible. Actually, to refer to it, you don’t need to use any prefixes then. Types of Python Variable Scope There are 4 types of Variable Scope inPython, let’s discuss them one by one: ...
file, not just from the point in the source file where it is declared.Debug Toolsession variables always have a higher scope than program variables, and consequently have higher precedence than a program variable with the same name. The program variable can always be accessed through qualification...
