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

printf("%d",c);
for(c=num-r-1; c>=1; c--)
printf("%d",c);
printf("\n");
