Pascal triangle

[vishuvishal]

Hi folk,


I have a code for pascal triangle

Code: [Select]

@echo off
setlocal ENABLEDELAYEDEXPANSION
Title Pascal's Triangle
:Begin
cls
(set n=)
set /p "n=Input (?? Lines) : "
if not defined n goto :Begin
(set /a nspace=n-1)
(set temp_var=!nspace!)
for /L %%a in (1,1,!n!) do (
for /L %%n in (1,1,!nspace!) do (
for /F "Delims=" %%s in ('echo. ') do <nul set /p "=%%s"
)
(set /a nspace-=1)
(set Bil[%%a][1]=1)
(set Bil[%%a][%%a]=1)
if %%a gtr 2 for /L %%x in (2,1,!temp_var!) do (
set /a "prev=%%a-1"
set /a "prev_coloum=%%x-1"
call set "temp_1=%%Bil[!prev!][!prev_coloum!]%%"
call set "temp_2=%%Bil[!prev!][%%x]%%"
set /a "Bil[%%a][%%x]=temp_1+temp_2"
)
for /L %%b in (1,1,%%a) do <nul set /p "=!Bil[%%a][%%b]! "
echo.
)
pause>nul
goto :Begin
:END

It is using concept of array.

So, I am confused with each lines.
Can any comment on each lines and explain this to me.

Thanks and regards

I apologize for this.

But, wanted some explanation.
You routed me to same old posts.
I know if you want. You can explain me all these.
BC programmer.
Thank you in advance. It will be little lengthy time consuming. But will satisfy my curiosity.
I also want to devote my knowledge to this forum helping others.
So, want to be little knowledgeable like you all. Will take time. But, it is not impossible.

Thanks and regards.
