Berikut saya berikan contoh code untuk membuat formasi X dengan karakter '*', untuk codenya silahkan simak di bawah ini:
begin
     read(n);
     for i:=1 to n do
         begin
              for j:=1 to n do
                  begin
                       if (j=i) or (j=(n-i+1)) then
                          begin
                               write('*');
                          end
                       else
                           write(' ');
                  end;
              writeln;
         end;
end.

program prima;
uses wincrt;
var i,n:integer;
prm: boolean;
begin
write ('masukkan nilai n: ');
read (n);
prm:true;
if (n mod 2 = 0) and (n<>0) then
write (n,' bukan bilangan prima')
else
begin
for i:=2 to n-1 do
begin
if n mod i = 0 then
begin
prm:=false;
end;
end;

if prm=false then
write (n,' bukan bilangan prima')
else
write (n,' bilangan prima');
end;
end.

program ulang;
uses wincrt;
var i,j,n: integer;
begin
write ('masukkan nilai n: ');
read (n);
for i:=n downto 1 do
begin
for j:=n downto n-i+1 do
begin
write (j);
end;
writeln;
end;
end.
