Hi,
I have practice to write the checkerboard pattern like below using HLA
programming language:

xxxxxxxxooooooooxxxxxxxxooooooooxxxxxxxxooooooooxx xxxxxxoooooooo

xxxxxxxxooooooooxxxxxxxxooooooooxxxxxxxxooooooooxx xxxxxxoooooooo
xxxxxxxxooooooooxxxxxxxxooooooooxxxxxxxxooooooooxx xxxxxxoooooooo

what is could produce is as below:
------------------------------------------

Code:

---

program chess;
#include("stdlib.hhf");
static
  s:char := 'x';
  e:char := 'o';
  z:int32;

  i:int32; //1st *
  j:int32; //1st _
  b:int32;
  t:int32;

  x:int32;
  y:int32;       
  a:int32;
  q:int32;

begin chess;

//main looping
 for (mov(0,z); z<4; add(1,z)) do

//1st looping
  for(mov(0,t); t<4; add(1,t))do

    for(mov(0,j); j<4; add(1,j)) do

        for(mov(0,i); i<8; add(1,i)) do
          stdout.put(s);
        endfor;

        for(mov(0,b); b<8; add(1,b)) do
            stdout.put(e);
        endfor;

    endfor;
    stdout.newln();

  endfor;


//2nd looping
  for(mov(0,q); q<4; add(1,q))do

    for(mov(0,y); y<4; add(1,y)) do

        for(mov(0,x); x<8; add(1,x)) do
          stdout.put(e);
        endfor;

        for(mov(0,a); a<8; add(1,a)) do
            stdout.put(s);
        endfor;

    endfor;
    stdout.newln();

  endfor;

//end main for
 endfor;

end chess;

Is that my code could be use? The requirement is to use only
5 FOr loops, 4 stdout.putcSize, and 2 stdout.newln.
At here i have use up 9 FOR loop, 4 stdout.put, and 2 stdout.newln().

Could any sensei pls give some lecturing at me. Pls advice. Thanks.

Im definetly no sensei but maybe you could do something like

Code:

---

for eight_squares_high

    for four_rows_per_square

        for four_xo_patterns

            for 8_x_wide
                put an x
            endfor

            for 8_o_wide
                put an o
            endfor
       
        endfor
   
        newline

    endfor

    interchange Xs and Os

endfor

---

Or something like this (not especially efficient, but does the trick, also mainly algorithmic as I don't know the language you're using)....

Code:

---

c = 'x';
for(mov(0,i); i<32; add(1,i)) do
        for(mov(0,j); j<8; add(1,j)) do
                for(mov(0,k); k<8; add(1,k)) do
                        stdout.put(c);
                endfor;
                if (c is an 'x') then make it an 'o' else make it an 'x'
        endfor;
        stdout.newln();
        if ((i mod 4) != 0) then
                if (c is an 'x') then make it an 'o' else make it an 'x'
        endif;
endfor;

Hi, thanks a lot. I like the idea.
Have a nice day.

He is using HLA or high level assembler.
