IN C

Write a program that does the following: 1) Prints a Hello for every Ctri-C the user sends during the first 100 seconds of its life. But these Hellos are printed only after 100 seconds are over. (10 points) 2) "Ignores" any Ctrl-C's the user sends after first 100 seconds of its life. Here "ignoring" means ignoring the signal (and not simply blocking it). (10 points) 3) Terminates after roughly 200 seconds of life. (10 points) Hints 1. To ignore a signal, you must modify its signal handler using sigaction0 2. To print a hello, you must install a signal handler for the signal using sigaction0. 2. You can use alarmO to send yourself a SIGALR.M signal after a specified number of seconds. 3. A signal can be waited upon using a signal handlersigsuspendO OR using sigwait0. 4. In order to block a signal, you must modify the signal mask using sigprocmaskO Write a program that does the following: 1) Prints a Hello for every Ctri-C the user sends during the first 100 seconds of its life.
