Find the Number in Array using Assembly Language | Search Value from Array using Assembly Programming Language

 

Write a program in assembly language to scan a value form keyboard and then search it from array of ten values and display the message if value Found or not Found

Here is an example in Emu8086 Assembly language that prompts the user to input a value. Search for that value in array of ten integers value and displays a message whether the value is found or not found

Program Source Code

include "emu8086.inc"

org 100h   

.model small

.data

  num db 10,12,3,4,5,6,11,7,8,9 

  msg db "Enter Number $"

  msg1 db 10,13, "number is Found  $"

  msg2 db 10,13, " number is not Found $"  

  value db ?   

.code

    

     mov ax,@data

     mov ds,ax 

     lea dx,msg

     mov ah, 09h

    int 21h

    ; read value from keyboard

    mov ah, 01h

    int 21h

    sub al, '0' ; convert ASCII digit to binary

    mov value, al     

     lea si,num ; mov si offset num

     mov cx,10

     mov al,value

   Searching:

      mov bl,[si]

      cmp al,bl

      jz NumFound 

      inc si

     Loop Searching 

       mov dx,offset msg2  

       mov ah,9

       int 21h       

     .EXIT      

      NumFound:

        mov dx,offset msg1  

       mov ah,9

       int 21h

        

      .EXIT

ret

Output Code

Explain the program how it work

1.      The program defines an array of ten integer value and two message to display depending on whether the value is found or not found

2.      The program prompts the user to input a value to search for

3.      The program reads the values from the keyboard and converts it from ASCII to binary

4.      The program loops though the array and compare each element to the value. If the value is found the program jumps to the ‘found’ label. If the end of the array is reached without finding the value, the program displays the not found message

5.      If the value is found the program displays the found message and exits

6.      The program exits and return to DOS screen
