Question

2. Write an Assembly program using Super Simple CPU Instruction set that takes input 3 numbers from the user and outputs 1 in the output box if the sum of the first two inputs is greater than the sum of the last two inputs; otherwise it outputs o in the output box. Example1, if user inputs the numbers 10, (2.0), 11, (3.0), and 1,(1,2) then the output should be 1 (since 2.0 + 3., is greater than 3.. +1,). Example 2, if user inputs the numbers 100,(4.), 11, (3.c), and 100, (4.c) then the output should be 0 (since 4, +3, is not greater than 3,0 +4.0).

Answer 1

solution:

Given data:

.model small

.stack 100h

.code

main proc

mov ah, 1

int 21h

mov bl,al

mov ah,1

int 21h

mov bh,al

mov ah,1

int 21h

mov cl,al

add bl,bh

sub bl,48

add cl,bh

sub cl,48

cmp bl,cl

jge a

mov ah,2

mov dl,0

int 21h

jmp exit

a:

mov ah,2

mov dl,bl

int 21h

exit:

mov ah,4ch

int 21h

main endp

end main
