Consider the following scenario: multiple threads execute function Compute and all of them modify a shared variable SharedCounter (critical section). Add the appropriate code (using semaphores or mutex) to make sure that only one thread modifies SharedCounter at the time.

#include  #include  int SharedCounter = 0;   void *Compute(); int main(int argc, char *argv[]) { /* multiple threads are created. All of then execute Compute*/ /* wait for threads to exit */   printf("SharedCounter = %d ", SharedCounter);   } void *Compute() { int increment;    SharedCounter += increment;    pthread_exit(0); }
