3.3 Signals for Exceptions The signal sent for division by zero is SIGFPE. Write a main program and a signal handling routine that prints the message "caught a SIGFPE" for a floating point error (e.g. division by zero). Include a division by zero in the main program like the one below: / the division needs to use a variable or gcc will not compile the instruction/ int a 4; If you don't see your message, then you didn't set up the signal handler correctly. Hint: Add an exit statement at the end of the signal handler so the program will terminate In the report, please 5 pts) include your source code (5 pts) explain which line should come first to trigger your signal handler: the signal statement or the division-by-zero statement? Explain why
