I finally did it !!!
After 2 hours [ I wish that I could function better ] of trying to do it I did it.
I'm not sure if I could tweak the code and make it more simple but it doesn't matter because it does what I wanted it to do at the start.
void getcircle(int *xp,int *yp);
void circle(int x,int y);
void circle(int x, int y)
void getcircle(int *xp, int *yp)
scanf("%d %d", &*xp,&*yp);
