(newbie) how to make a pinetree using for

Pinetree using stars

I need to make a program that asks the user the number of lines the pinetree will have then it should make a pinetree using the correspondent amount. It needs to be with one star in nested loops.

Example1:

Enter the amount of lines: 3


*

* *

* * *

Example2:

Enter the amount of lines: 5

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


Thanks in advance. Much is appreciated.

PS The pinetree is suppose to be like an actual tree when I post this the stars will all be on the left margin all together.

What's the problem?

Get yourself a piece of graphing paper. Draw a thick vertical line down the left side. This represents the left edge of your terminal. Draw your stars. It might look something like:

┌─┬─┬─┬─┬─┬─┬─┬─┬─┬─
│ │ │ │ │ │ │ │ │ │
├─┼─┼─┼─┼─┼─┼─┼─┼─┼─
│ │ ║ │ │ │ │ │ │ │
├─┼─╫─┼─┼─┼─┼─┼─┼─┼─
│ │ ║ │ │*│ │ │ │ │
├─┼─╫─┼─┼─┼─┼─┼─┼─┼─
│ │ ║ │*│*│*│ │ │ │
├─┼─╫─┼─┼─┼─┼─┼─┼─┼─
│ │ ║*│*│*│*│*│ │ │
├─┼─╫─┼─┼─┼─┼─┼─┼─┼─
│ │ ║ │ │ │ │ │ │ │
├─┼─╫─┼─┼─┼─┼─┼─┼─┼─

Now you can count how many spaces you need and how many stars you need for each row.
You should recognize a pattern. This will help you write your loop.

Good luck!

When I created this kind of program,I used 3 loops,1 for horizontal asterisk creation and 1 for spaces,and my main loop. As you can see Duoas illustration you can't use even numbers for printing asterisk. To make it look like a pine tree use decrement when printing the spaces and increment for the asterisk.
