Variable Scope

1. Local Scope: Variables defined inside a function are only accessible within that function.

   • Example: A variable x inside a function cannot be accessed outside it.

2. Global Scope: Variables defined outside functions are accessible throughout the program.

   • Example: A global variable y can be used in any part of the program.

3. Best Practices:

   • Use local variables when possible to avoid conflicts.
   • Clearly document global variables.
