Answer:
B. until another thread issues a notify on the semaphore.
Explanation:
A semaphore is a variable that is shared between threads and is not negative. It also acts as a calling mechanism that uses two atomic operations wait and signal for synchronization of processes.
A thread that is waiting for a process can be signaled by another thread.
A semaphore puts a thread to sleep until another thread issues a notify on the semaphore.
The wait operation will get a semaphore or otherwise wait if the busy S semaphore is available.
The signal operation will release a semaphore or wake a process if there is a thread waiting for S.
Answer:
#include <stdlib.h>
#include <time.h>
#include<iostream.h>
int main(void) {
int seedVal = 0;
seedVal = 4;
srand(seedVal);
/* Solution*/
cout<<rand() % 149 + 100<<endl;
cout<<rand() % 149 + 100<<endl;
return 0;
}
Explanation:
We start with the required include statements to enable use of srand, rand and time functions. I have also added iostream library to use "cout" function.
After that, the seed is initialized using srand(). And then the two rand functions are called with ranges including and between 100 and 149, and printed out.
