Star Structure

Q. Write a c program to print the following star structure:

*********
 *******
  *****
   ***
    *
   ***
  *****
 *******
*********

Ans.
/*c program for print the star structure*/
#include<stdio.h>
#include<conio.h>
int main()
{
 int num,n,r,c,sp;
 printf("Enter number of rows: ");
 scanf("%d", &num);
 printf("\n");
 n=num;
 for(r=1; r<=num; r++)
 {
  for(sp=1; sp<=r; sp++)
    printf(" ");
  for(c=1; c<=n; c++)
    printf("*");
  for(c=num-r; c>=1; c--)
    printf("*");
  n--;
  printf("\n");
 }
 for(r=2; r<=num; r++)
 {
  for(sp=num-r+1; sp>=1; sp--)
    printf(" ");
  for(c=1; c<=r; c++)
    printf("*");
  for(c=r-1; c>=1; c--)
    printf("*");
  printf("\n");
 }
 return 0;
}

The output of above program would be:
