#include<stdio.h>
#include<conio.h>
main()
{
 int i,j,row,t=1;
 clrscr();
 printf("Enter the number of rows\t");
 scanf("%d",&row);
 for(i=0;i<row;i++)
 {
  for(j=0;j<=i;j++)
  {
    if (t<10)
       printf("%d  ",t);
    else
       printf("%d ",t);
     t++;
   }
   printf("\n");
  }

 getch();
}
