data _null_;
put '   *   ';
put '  ***  ';
put ' ***** ';
put '*******';
run;

Submit. Find your pyramid erected inside the log.

i have to get the output by hard coding (by doing iterations).

The output must be in pyramid shape.it has to be done in core coding by using do loop.

Hi ksharp,
Thanks for helping me,
pyramid must be build using normal coding not by matrix or graph plot.

How are graph plots "abnormal"?

What is your destination? A text file? HTML? RTF? PDF?

Note that the FONT used to display the output can result in an uneven appearance because of the way spaces may be displayed with proportional fonts (which is one possible reason to use graphic output)

Sounds like an algorithm puzzle. Perhaps a class assignment?

Given a list of records with asterisks left-aligned, build a pyramid (centered) version of these records? Sounds like you need to:

Learn the length of the longest record (let's call it X)
Pad each record with spaces on either side of the asterisks -- prepend and append X/2 - length(trim(current_record)), adjusting by one when that length is an even number.

It could be a fun little programming golf puzzle...but maybe people would be more inclined to help if they knew this wasn't just your homework? Or an interview question? Is there a business goal?

OK. How about this one .



data have;
input x $;
n=0;
do i=length(x) to 1 by -1;
 n+1;
 if mod(n,2)=0 then substr(x,length(x)-n+1,1)=' ';
 y=reverse(substr(x,2))||x; 
end;
cards;

run;
