Ubun in or Mac Termina Part one-Threads Programming (0.5% Write a program in C that prompts the user to enter n which represents the number of threads, your program should then create n threads and wait for them to finish the execution. Threads from 1. should print the numbes from 1 Whereas threads from+1n should print their unique ids along with an informative message. Part two-Tracing (1.0% Trace the below code and answer the following questions: inc include include include cuntstd.h> estdio otdinc(votd n) rtntf("I'n thread nt main) threadt tid; number %ld and ny value is %d ", pthread-self(),K*2); thread create(&tid, NULL,inc, NULL) thread exit(NULL) 1. 2.

How many threads does this process have? 2. What is the name of the function that is executed by all threads? 3. What is the parameter that is passed to the thread function? 4. Choose the correct type for the variable x a. x is a global variable shared among al threads b. x is local and not shared among all threads S. Choose the correct type for the variable y a yis a global variable shared among all threads b. y is local and not shared among all threads 6.
