This program is designed to demonstrate the extraction and formatting of virtual address components, such as segment, page, and offset, from a 31-bit address. It uses bitwise operations to isolate these components from a given virtual address and then prints them in a formatted manner.

• Extracts the segment, page, and offset from a 31-bit virtual address.
• Utilizes bitwise operations for extraction:
  • Offset: Extracted using a bitwise AND operation with 0x00000fff.
  • Page: Extracted by first ANDing with 0x00ffffff and then shifting the result right by 12 bits.
  • Segment: Extracted by shifting the address right by 24 bits.
• Displays the original address and its extracted components in a formatted output.

• The program begins by defining the main function, which initializes a 31-bit address and variables for the segment, page, and offset.
• It then extracts these components using bitwise operations.
• The printFormattedResults function is called to print the original address and its components.
• Finally, the extracted values are reset to 0, demonstrating the concept of variable reusability and function isolation.

Upon execution, the program will print the original 31-bit address and its extracted components (segment, page, and offset) in a hexadecimal format.
