Write a C program for:
One technique for dealing with deadlock is called “detect and
recover.” In this scheme, some procedure is used
to identify when a deadlock occurs, and then another procedure
is used to deal with the blocked processes. One technique to
identify a deadlock is to maintain a resource graph that identifies
all processes, all resources, and the relationships between them
(that is, which processes exclusively own which resources, and
which processes are blocked waiting for which...

Given the table, suppose we have avoided circular-wait by ordering the resources in the order R1 -> R2 -> R3 -> R4 and enforcing that each process must request resources in the ascending order. Show one allocation possibility of R1-R4 to P1-P4 and the corresponding wait-for graph. If there is a deadlock, please explain why or why not?

Assume that we desire to have deadlock-free mutual exclusion using locks on a shared object implemented via a set of shared registers. Suppose we allow threads to go through the lock method without writing to any of the shared registers? In general, it will be impossible to tell if a thread is in the critical section by examining the shared object. It will result in deadlocks. Both (a) and (b) Neither (a) nor (b) Suppose a thread attempts to lock...
