 Ans:-  #include "stdio.h"
main()
{
        int i,j,n,sp,st=1;
        printf("Enter total rows");
        scanf("%d",&n);
        sp=n-1;
        for(i=1;i<=n;i++)
        {
                for(j=1;j<=sp;j++)
                        printf(" ");
                for(j=1;j<=st;j++)
                        printf("*");
                printf("\n");
                sp=sp-1;
                st=st+2;
        }
}
