Logic to print pyramid star pattern
* *** ***** ******* *********
- Input number of rows to print from user. Store it in a variable say rows.
- To iterate through rows, run an outer loop from 1 to rows. The loop structure should look like
for(i=1; i<=rows; i++). - To print spaces, run an inner loop from i to
rows - 1. The loop structure should look likefor(j=i; j<rows; j++). Inside this loop print single space. - To print star, run another inner loop from 1 to
2 * i - 1. The loop structure should look likefor(j=1; j<=(2*i - 1); j++). Inside this loop print star. - After printing stars for current row, move to next line i.e. print new line.
