Thread: A little problem

Hello, I need little help with this. Basically what I want for the program to do for me is to show on the graphic window n number of circles with the positions i give it [a,b in my situation (that is x.y)]

I made this and it does print out the first circle but when ever I want to enter the positions for the 2nd circle it closes

Code:

void circle(int a,int b);

int main()
{
  int a,b;
  int n,i;


  openwindow();
  printf("Number of circles\n");

  scanf("%d", &n);

  if(n<=0)
  {
    printf("Please enter a number higher than 0\n");
    getch();
    return 0; 
  }
  if (n>3)
  {
      printf("The number of circles is to high\n");
      getch();

  return 0;
  }

 
  printf("Enter the position of the circle/s\n");


  
  for(i=0; i<n; i++);
  {
      scanf("%d %d", &a,&b);       // Im not sure how to fix this .. what ever i try I get errors like no pointer to "i"? 
  }

   circle(a,b);
        
  getch();
  
  return 0;
}

void circle(int a,int b)
{
      circle(a,b,200);
}

I would like if someone could give me a hint how to fix the problem I have, iv been trying to fix this for hours but i get an even more complicated problem after.

You should not have a semicolon at the end of for(i=0; i<n; i++);

Thank you! I did remove the semicolon and it doesn't close anymore at the 2nd input
How ever it prints out in the graphic window only one circle

example what it does

*enter the number of crircles
->2
*enter the position of the circle
x->0
y->0
x->100 [ it prints out only the last circle while skipping the first one ]
y->100


Iv been trying many things but the error list only gets flooded ...

Thanks Salem!!!!
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.

Code:

void getcircle(int *xp,int *yp);
void circle(int x,int y);

int main()
{
    int n;
    int x,y;
    int i=0;
    openwindow();

    scanf("%d",&n);

    while (i<n)
        {
        i++;
        getcircle(&x,&y);
        circle(x,y);
        }
    }
    


void circle(int x, int y)
{
    circle(x,y,200);
}


void getcircle(int *xp, int *yp)
{
    scanf("%d %d", &*xp,&*yp);
}
