Implementation

Design and implement a comprehensive Process Control Block structure.

Requirements:

Define struct Process with all essential fields
Include: identification, processor state, process state, memory info
Include: file descriptors, accounting, scheduling info
Implement PCB initialization
Implement PCB display function (show all fields)
Implement PCB copy (for fork())
Implement PCB state transitions (ready→running→blocked)
Demonstrate PCB usage with multiple processes
Show PCB changes during context switch

Why This Matters

The struct you're designing mirrors Linux's real `task_struct` in `sched.h`, which has grown to hundreds of fields and is why `/proc/[pid]/status` can expose dozens of process attributes to tools like `ps` and `top`. Getting the fork()-copy semantics right here matters in production: forgetting to reset a field like open file descriptors is exactly the kind of bug that caused real fd-leak incidents in forking servers.
