#include<stdio.h>

int main()

{

    int i, space, rows, star=0;

    printf("Enter the number of rows\n");

    scanf("%d",&rows);

     

    /* printing one row in every iteration */

    for(i = 1; i <= rows; i++) {

        /* Printing spaces */

        for(space = 1; space <= rows-i; space++) {

           printf(" ");

        }

        /* Printing stars */

        while(star != (2*i - 1)) {

            printf("*");

            star++;;

        }

        star=0;

        /* move to next row */

        printf("\n");

    }

    return 0;
