Answer / Jasvant Singh

In Object-Oriented Programming (OOP), Scope and Storage Class are essential concepts that determine the visibility, accessibility, and lifespan of variables and objects within a program. Here's an explanation of both:

1. Scope:
- Local Variable: Declared within a function or block, visible only within that scope.
- Global Variable: Declared outside any functions or blocks, accessible from anywhere in the program.
- Static Variable: Declared with the `static` keyword, maintained between function calls but still within the same scope.

2. Storage Class:
- Automatic (or auto): Created when a function or block is entered and destroyed once the function or block exits. Example: local variables in C++.
- Static: Allocated and deallocated only once during the entire execution of the program, maintaining its value between function calls. Example: static variables in C++.
- Extern: Declared outside any functions or blocks with no initial value. Used to define global variables that are shared across multiple source files.
- Register: Optimization directive to store a variable in a processor register instead of memory, which can lead to faster access times but limited space. Not supported by all compilers.
