Answer the questions on multithreading and concurrency. Answers without explanations will not get partial credits.

a. Given the following code excerpt

int count = 0; void thread_func() {

int temp = count;

count = temp + 1; }

What are the minimum and maximum possible final values for int count when there are five threads that execute thread_func ( ) concurrently? Describe the execution pattern for the threads that generates the minimum value.

Min: __________ Max:__________ Explanation:

b. Given the following code excerpt

int count = 0; void thread_func() {

for(int i = 0; i < 5; i++) { int temp = count; count = temp + 1;

} }
