ya, read up on the "put" command.

here's what the code will look like:

code:

put "   *" put "  ***" put " *****" put "*******"

sorri i wasnt clear
i dont want to just use "put"

i want to get a number, eg like 5 and make a christmas tree like this:
--*
-***
*****

again ignore the dashes

oh, okay thats a pretty good question actually. simplest way is to use repeat and a for loop and play around with it until you get it

heres what i came up with

code:

var base : int put "Enter base width : " .. get base for t : 1 .. base     put repeat (" ", base - t) ..     put repeat ("*", t * 2 - 1) end for

thanks for ur help!!!!!!

i need to make a circle now with the asterisks...i think the closest thing i can make is an octagon though......so can i use repeat for making a "circle"?

interesting problem.
heres what i came up with:

code:

var radius : int put "enter radius : " .. get radius var x, y : real x := -radius - 1 for c : 1 .. radius * 2 + 1     x += 1     y := sqrt (radius ** 2 - x ** 2)     locate (round (x) + maxrow div 2, round (-y) + maxcol div 2)     put "*"     locate (round (x) + maxrow div 2, round (y) + maxcol div 2)     put "*" end for

unfortunately in text the width of a character is less than its height, so it looks very, very off. also it looks off because locate requires rounding.

Hey, if u enter 5, it looks like a rupee in Zelda!

um....sorri if this sounds dumb.....but can u explain the code u did cuz i am new at this and i duno wat that code meant....

[Cervantes]

i don't really know what it means either I basically played around altering and fixing stuff until i came up with that.
but basically, i used the equation of a circle. thats x^2 + y^2 = r^2. rearange that so that we get y^2 = r^2 - x^2, then sqrt it all so we get y = sqrt (r^2 - x^2). so now we've got x and y values (got x because we are just increasing x every time). so now locate at (x,y) and draw a *. I've got 2 locates and 2 puts. look what happens when you take one of them out. and as for the for loop being 1 .. radius * 2 + 1, look what happens when you take off the + 1. look what happens when you take off the *2.

this is how i program try something, fix it, try more, fix more, until i get it to work. Then i know how to do it, and if i have the energy i rewrite the code nice and organized and add any features i want.
