Thread: Hello there:-)

You should post your code with your questions.
The number of *s on each line changes. What is the criteria for when the number increases and for when the number decreases? How is the line # of the line you are printing one related to the number of *s to go on that line?

The input # should equal the number of *'s in the middle of the "arrow head". It should begin by increasing from * to ** to *** to the number the user inputs. Then it should decrease in the same way. I have tried soooo many things. But everytime I mess with it I either get a straight line of *, or a infinite loop of them.......................grr!



Scanner input = new Scanner(System.in);
int starlength;

System.out.print("Please enter the number of *'s to span the length of your arrowhead:");
starlength=input.nextInt();
int row=1;
while(row<=starlength)
{
int star=1;
while(star<=row)
{
System.out.print("*");
star++;
}
System.out.println();
row++;

}}}



The output if the user inputs 5 is:

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



So any advice? Btw, thanks for responding Only girl in my class and I feel like the slow one

How does your code determine when it should decrease the number of *s on a line?

}s should not be nested all on one line. They should go on their own lines and be beneath the line with the beginning {

  {
       // some code 
       {
          // some more
       }
  }

Please Edit your post and wrap your code with[code=java]<YOUR CODE HERE>[/code] to get highlighting

Please edit your code and format it properly. Each nesting level within a set of {} should be indented 3-4 spaces
The } should NOT be directly beneath each other. See the simple example in my last post.

What if you used two loops? One for when the number increases and one for when it decreases.
