Question

#include ... void sig_handler(){ static int i = 1; printf("Beep\n"); alarm(i); ++i; } int main(){ struct sigaction sa; sa.sa_flags = 0; sa.sa_handler = sig_handler; if(sigaction(SIGALRM, &sa, NULL) != 0){ printf("Failed to bind handler.\n"); exit(1); } printf("Going into an infinite loop.\n"); alarm(1); while(1); return 0; }
Suppose the above program is run for 7.5 seconds after it prints "Going into an infinite loop". The program is run multiple times where the "system load" from other processes sharing the cpu will vary from none to many other processes. Which best characterizes how many times "Beep" is printed?

Answer 1

Answer:

Explained below

Explanation:

After the compiling the program it prints "Going to infinite loop" after that i started the timer till 4.5 sec. The program prints more than 4 beeps nearly 6-7 beep messages were printed.

The number "Beep" would always be strictly greater than 4.

Hence, if the above program is run for 7.5 seconds after it prints "Going in an infinite loop", it will print Beep for about 9-10 times. Hence, the number will always be greater than 7
