Question

Write an assembly program which prints the largest values among three variables. You can initialize three integers in data section (let's say 10, 45, 15).

Answer 1

Assembly program which prints the largest values among three variables : -

Here, we use N1,N2 & N3 for storing three variables. And, LRG for storing largest number among them.

Code:-

DATA SEGMENT
N1 DB 10H
N2 DB 45H
N3 DB 15H
LRg DB ?
ENDS
CODE SEGMENT
ASSUME DS:DATA CS:CODE
START:
MOV AX,DATA
MOV DS,AX
MOV AL,N1
MOV LRG,AL
CMP AL,N2
JGE LABEL1
MOV AL,N2
MOV LRG,AL
LABEL1:
MOV AL,LRG
CMP AL,N3
JGE LABEL2
MOV AL,N3
MOV LRG,AL
LABEL2:
MOV AH,4CH
INT 21H
ENDS
END START

Before Execution :

After Execution :

Now , you can see LRG variable has the largest.

(I have used 8086 emulator).
