Making Pyramid with C/C++

#include<stdio.h>
#include<conio.h>

void main()
{
   int i = 0, j , n ;
   clrscr();
   printf("How many rows in pyramid:");
   scanf("%d",&n);

   while(i<n)
   {
             j=0;
             while(j<=i)
             {
               gotoxy(30+j,10+i);
               printf("%d",j);
               j++;
             }
             j=0;
            while(j<=i)
             {
               gotoxy(30-j,10+i);
               printf("%d",j);
               j++;
             }
             i++;
             printf("\n");
   }

   getch();
}

Remarks
For making two sides pyramid we have used two while loops and another while loop for controlling rows. Here gotoxy () function takes the curser to the specified location.
