Answer :

Undefined behavior

Explanation:

The second statement results in undefined behavior because
it points to some location whose value may not be available
for modification. This type of pointer in which the
non-availability of the implementation of the referenced
location is known as 'incomplete type'.

Question: We would like to design and implement a programming solution to the reader-writer problem using semaphores in C language under UNIX. We assume that we have three readers and two writers processes that would run concurrently. A writer is to update (write) into one memory location (let’s say a variable of type integer named temp initialized to 0). In the other hand, a reader is to read the content of temp and display its content on the screen in a formatted output. One writer can access the shared data exclusively without the presence of other writer or any reader, whereas, a reader may access the shared memory for reading with the presence of other readers (but not writers).
