Answer:Here's a program in Assembly language that draws an 8x8 chessboard with alternating gray and white squares using Irvine32 library's SetTextColor and gotoxy procedures:
Explanation:
sql
Copy code
INCLUDE Irvine32.inc
ChessBoard MACRO row, col, color
mov edx, row
mov ecx, col
call gotoxy
mov eax, color
call SetTextColor
mov ah, 20h
mov dl, ' '
call WriteChar
ENDM
; main program
main PROC
mov ecx, 8 ; number of rows and columns
mov ebx, 0 ; counter
mov edx, 1 ; start row
mov eax, 0 ; start col
nextrow:
cmp edx, ecx ; compare row counter to total rows
jg done ; exit loop if all rows have been drawn
nextcol:
cmp eax, ecx ; compare column counter to total columns
jg newrow ; move to next row if all columns have been drawn
; draw square
ChessBoard edx, eax, 7 ; white square
add eax, 1 ; increment column counter
ChessBoard edx, eax, 8 ; gray square
add eax, 1 ; increment column counter
jmp nextcol
newrow:
mov eax, 0 ; reset column counter
add edx, 1 ; increment row counter
jmp nextrow
done:
exit
main ENDP
In this program, the ChessBoard macro is used to draw a square of a given color at a specific row and column position. The main procedure uses nested loops to iterate over each row and column, calling ChessBoard to draw each square in alternating gray and white colors.
Note that the colors used are specified using their VGA color codes (7 for white and 8 for gray). You can adjust these values to use different colors if desired.
