Ans.
/* c program for number structure */
#include<stdio.h>
#include<conio.h>
int main()
{
 int num,r,c,sp;
 printf("Enter loop repeat number : ");
 scanf("%d",&num);
 for(r=1; r<=num; r++)
 {
   for(sp=r; sp>1; sp--)
      printf(" ");
   for(c=r; c<=num; c++)
      printf("%d",c);
   for(c=num-1; c>=r; c--)
      printf("%d",c);
   printf("\n");
 }
 getch():
 return 0;
