Is it possible to start the program from the terminal and continue to work after closing the terminal?

I wrote a program that I run after connecting to the box through SSH. It has some user interactions, such as selecting parameters after a request, and usually I wait for the processes that it completes to complete before leaving the system, which closes the terminal and terminates the program. But now the process is quite long, and I do not want to wait while you log in, so how can I implement a workaround for this in C, please?

C- :

//do interactive stuff...  
if(fork())
     exit(0);
//cool, I've been daemonized.

If you know that the code will never exit on a machine other than linux or BSD, you can even use daemon()

//interactive...
daemon(0, 0);
//background...
