Answer 1

Code For All combinations of foreground and background colors:

Include Irvine32.inc

.data

str1 byte "F",0dh,0ah,0          ;character initialized (0dh,0ah for next line)

foreground Dword ?               ;variable declaration
background Dword ?
counter Dword ?

.code

main PROC

mov ecx,16                     ; initializing ecx with 16

l1:                             ;outer loop
mov counter,ecx
mov foreground,ecx
dec foreground
mov ecx,16



l2:                            ;inner loop

mov background , ecx
dec background

mov eax,background      ; Set EAX = background
shl eax,4               ; Shift left, equivalent to multiplying EAX by 16
add eax,foreground      ; Add foreground to EAX

call settextcolor       ;set foreground and background color


mov edx, offset str1    ; string is moved to edx for writing
call writestring


loop l2                  ;calling loop

mov ecx,counter

loop l1
    exit
main ENDP
END main
