What are the differences between Local and Global Variable?

Local Variable:

• Scope: Local variables are declared within a specific block, function, or scope.
• Lifetime: They exist only within the block or function in which they are declared.
• Access: Accessible only within the block or function where they are defined.
• Initialization: This may not be initialized by default and must be explicitly assigned a value before use.
• Memory Allocation: Typically allocated on the stack.
• Visibility: Not visible or accessible outside the block or function where they are declared.

Global Variable:

• Scope: Global variables are declared outside of any function or block, making them accessible throughout the entire program.
• Lifetime: They exist for the entire duration of the program's execution.
• Access: Accessible from any part of the program, including functions and blocks.
• Initialization: May be initialized or uninitialized, and they retain their values between function calls.
• Memory Allocation: Typically allocated in the data segment of the program.
• Visibility: Visible and accessible from any part of the program.
