```
*
***
*****
*******
```

here is my code

You're not going to call your new line with that for loop.

```
for(i=0;i<10;i++)
{
for(j=0;j<i;j++)
{
printf("*");
}
printf("\n");
}
```

Will now give the output:

*

**

So you now need to change the logic to add some spaces to make your * centre. I'll leave that one with you, once you have some updated code if you need any more help post back.

As I said, you need to add some formatting to cnetralise the * in each row. Until you have some code to show how you've attempted that I can't really help you.

To find the center column for the first *, you can use either the number of rows in the "tree", or the number of *s, in the bottom row.

So if the bottom row has 7 *s, then 7/2 equals 3. So you should have 3 spaces before the * on the first row. You can use a for loop (outer one), to code this:

```
//handles the outer row configuration
for(numstars=1;numstars<=botmRow;numstars+=2) {
numspaces = (botmRow - numstars)/2;
//handles the spaces before the stars
for(i=0;i<numspaces;i++)
print one space here
//prints out the star/s
for(i=0;i<numstars;i++)
print out star/s here
}
```

So the top row could be seen as:

`spc spc spc * spc spc spc`

because the top row will always have just ONE star. So all the other char's will have to be spaces. :)

Now for each row, the number of stars increases by 2, and that means the number of spaces on each side of the stars, will decrease by 1 (since there are two sides, and 2 * 1 = 2.

imo you don't want to use tabs for this assignment.
