The following code is an incorrect implementation of the bounded-buffer single producer and single consumer program. Pick three answers that are *CORRECT* in fixing the program to work even when the consumer and producer threads run simultaneously. #include #include #include #include #define BUFFER_SIZE 10#define COUNT 100int buffer;int in=0;int out=0;void enqueue(int data) {   buffer=data;   in = (in + 1) % BUFFER_SIZE;}int dequeue() {   int data;   data = buffer;   out = (out + 1) % BUFFER_SIZE;   return data;}void *producer(void *dummy) {   int i=0;   int count = (int) dummy;   while(i < count) {       enqueue(i++);      printf("Producing value %d\n",i);   }  return NULL;}void *consumer(void *dummy) {   int data;   int count = (int) dummy;   int i = 0;   while(i < count) {        data=dequeue();        printf("Consuming value %d\n",data);        i++;   }   return NULL;}int main() {   pthread_t tid;   pthread_create(&tid,NULL,producer,(void *)COUNT);   consumer((void *)COUNT);   pthread_join(tid,NULL);   return 0;}

In the prototyping phase of an Arduino-based project, why is it important to test both an input and output component together before final assembly?    

Single answer: xchgl is a x86 machine instruction that reads a 32bit value from a memory location and sets a new value to the same memory location as a single atomic instruction. The following xchg is the mutual exclusion (mutex) implemented in xv6 os kernel using a xchgl x86 instruction. For your understanding, the machine effects are described in C.   static inline int xchg(volatile int *addr, int newval) { uint result; /* atomic read followed by update in a C version */ result = *addr; *addr = new; return result;} Select one that *CORRECTLY* implements a mutual lock to enter a critical section (mutual exclusion) using the xchg above.
