Write a program to add an array of 8 bit numbers using assembly language of Intel 8085?

Answer 1

To add an array of 8-bit numbers using Intel 8085 assembly language, you can use the following program structure:

MOV M, A         ; Initialize the accumulator
LXI H, 2000H     ; Load the address of the array into HL register pair
MVI C, 08H       ; Set the counter to 8 (number of elements)
XRA A            ; Clear the accumulator for the sum

ADD_LOOP: 
    MOV A, M     ; Load the current array element into the accumulator
    ADD A        ; Add it to the accumulator
    INX H        ; Move to the next element in the array
    DCR C        ; Decrement the counter
    JNZ ADD_LOOP  ; Repeat until all elements are added

; The sum is now in the accumulator (A)

This program initializes the address of the array, clears the accumulator, and iterates through each element, adding them together before storing the result in the accumulator.
