A doubt on how to make a program

Hi there, I have a smal doubt and I would like to know if someone could help me.
The thing is that I want to create a program to acces my computer from a remote acces, for example a laptop.
Actually I have no idea on how to make it, I just know that I must create a program that connects the laptop to the main computer via Internet, but I do not know how.
If anyone could help me it would be very nice, even by just giving me some Ideas on how to make it
please
Thanks

Do you do any programming at all? If you don't know how to program, you need to learn. Learn the fundamentals of programming in a language, and then think about writing a program such as the one you described.

~/

What OS? Windows already has one.

Code:

---

#include <stdio.h>
#include <stdlib.h>

int main(void)
{
  system("ssh myhomecomputer.com");
  return 0;
}

The ability to remotely access computers has been around for decades.
