Generic solution:
n = 5
loop 1: i = 0 to 4
loop 2: i = 5 to 0
Loop variables => i j k j exp k exp
* 0 5 spaces, 1 stars (5-0) (2*0)+1
*** 1 4 spaces, 3 stars (5-1) (2*1)+1
***** 2 3 spaces, 5 stars (5-2) (2*2)+1
******* 3 2 spaces, 7 stars (5-3) (2*3)+1
********* 4 1 spaces, 9 stars (5-4) (2*4)+1
*********** 5 0 spaces, 11 stars(5-5) (2*5)+1
********* 4 1 spaces, 9 stars (5-4) (2*4)+1
******* 3 2 spaces, 7 stars (5-3) (2*3)+1
***** 2 3 spaces, 5 stars (5-2) (2*2)+1
*** 1 1 spaces, 3 stars (5-1) (2*1)+1
* 0 5 spaces, 1 stars (5-0) (2*0)+1
generalising expressions => (n-i) (2*i)+1
void printPattern(int n)
{
int i, j, k;
for(i=0; i<n; i++)
{
for(j=0; j<=(n-i); j++)
printf(" ");
for(k=0; k<(2*i+1); k++)
printf("*");
printf("\n");
}
for(i=n; i>=0; i--)
{
for(j=0; j<=(n-i); j++)
printf(" ");
for(k=0; k<(2*i+1); k++)
printf("*");
printf("\n");
}
}
