process?? Do you have any ideas?

#include <stdio.h>

union discord {
unsigned char s[8];
unsigned long long v;
};

static union discord service = {
.s = "service"
};

static union discord process = {
.s = "process"
};

int main(void)
{
printf("The answer is %llu\n", service.v - process.v);
return 0;
}

Hmm, what do you mean by "service.v - process.v"? Is it mean that
Service is somethiing above process??

If you run a program, the running program is a process. If you dig further,
a process has a memory space associated with it and at least one thread.
Further, resources like e.g. open files are bound to a process. Note that
the terms task and process are used interchangeably, with task being used a
bit more often under Unix, I believe.

A service is a program that provides some service, like e.g. a timeserver,
webserver etc. Note that under Unix, the term service isn't used as often,
this is rather used in the MS Windows context. Under Unix, a service is
rather called daemon. Common to them is that they don't have a user
interface like e.g. a GUI or the standard input/output/error streams.
Rather, they are controlled by IPC mechanisms like signals.

So can i say that service is a "kind of" process witch , rather than
communicating with user communciates with other processes?
