Question

Answer 1

On Windows, you need to create a Windows/Linux/Mac Service or run the process in background. On Linux you need to create a daemon service or run the process in background. Services allow to automatically start the process on boot.

Answer 2

#include <stdlib.h>

int main()
{
    system("echo HelloWorld &");

    return 0;
}

This will spawn a new process.

Note: In general for the purpose of portability, avoid system functions.
