Wait online! !! Regularly check whether the program is not responding, and if not, restart the program. How to achieve?

I wrote a sending and receiving program for SMS cats, which is executed every 30 seconds.

Questions are as follows:
1. How to check whether the program runs normally?

2. If the program is not responding, I want to restart the program, how to achieve it?

Write a separate program and use Winsock to communicate with the main program regularly. If no response is received, it means there is no response and restart.

Write a monitoring daemon to determine the time period between the last run and this inspection, the status value of the sending and receiving program
If it's not right, just hang and renew
