Question

Using NASM, using jz, cmp, flags, loops also use the register 32 bit Task:

Design and write an assembly code that will determine if a given year is a Leap Year. Things to consider

How to change a string of numbers into its numerical counterpart o Helpful Hit:

Take a 4-digit string

Get the thousands digit

Multiply by 10

Add the hundred’s digit

Multiply by 10 etc.….

What defines a leap year A year is a leap year if it is divisible by 4 and not divisible by 100, unless it is also divisible by 400

. Would any loops (jmp to self), or if else statements (je or jne) that would be useful Loop: ~~~~ Code ~~~~ jmp Loop Compares: cmp ~x~, ~y~ je ~~something~~ jne ~~something else sample output : Type Year: 2000 This year is a leap year type Year: 2005 This year is not a leapy year

Explanation / Answer

Assembly code for whether the given year is Leap Year or not?

assume ds:data1,cs:code1

data1 segment

msg db 0ah,0dh,'Enter the year$'

number db 6,0,6 dup('$')

ys db 0ah,0dh,'yes,It is a Leap Year$'

n db 0ah,0dh,'no,It is not a Leap Year$'

data1 ends

code1 segment

start:mov ax,seg data1

mov ds,axlea dx,msg

mov ah,09h

int 21hlea dx,number

mov ah,0ah

int 21h

lea bx,number+4

mov ah,[bx]

mov al,[bx+1]

aad

mov bl,04h

div bl

and ah,0ffh

jz yes

lea dx,n

mov ah,09h

int 21h

jmp down

yes:lea dx,ys

mov ah,09h

int 21h

down: mov ah,4ch
