Program to find whether a number is positive and negative in 8085 microprocesser?

Answer 1

Oh, dude, to find out if a number is positive or negative on an 8085 microprocessor, you can use the sign flag (SF) in the flags register. If the sign flag is set, it means the number is negative. So, like, just check if the SF is 1, and you've got your answer. Easy peasy lemon squeezy!

Answer 2

LXI H, 6000H : Initialize memory pointer

MVI C, 00H : Initialize number counter

MVI B, 00H : Initialize negative number counter

MVI E, 00H : Initialize zero number counter

BEGIN:MOV A, M : Get the number

CPI 00H : If number = 0

JZ ZERONUM : Goto zeronum

ANI 80H : If MSB of number = 1i.e. if

JNZ NEGNUM number is negative goto NEGNUM

INR D : otherwise increment positive number counter

JMP LAST

ZERONUM:INR E : Increment zero number counter

JMP LAST

NEGNUM:INR B : Increment negative number counter

LAST:INX H : Increment memory pointer

INR C : Increment number counter

MOV A, C

CPI 32H : If number counter = 5010 then

JNZ BEGIN : Store otherwise check next number

LXI H, 7000 : Initialize memory pointer.

MOV M, B : Store negative number.

INX H

MOV M, E : Store zero number.

INX H

MOV M, D : Store positive number.

HLT : Terminate execution

Answer 3

In the 8085 microprocessor, you can determine whether a number is positive or negative by examining the most significant bit (MSB) of the number in its binary representation. If the MSB is 0, the number is positive. If the MSB is 1, the number is negative. You can use the sign flag (S) in the flags register to check the result of the operation and determine the sign of the number.

Answer 4

Well, honey, in the 8085 microprocessor, you can use the sign flag (S flag) to determine if a number is positive or negative. After performing an operation on the number, you can check the S flag to see if it's set (negative) or reset (positive). So, just check that S flag like you're checking for drama at a family reunion, and you'll know if your number is feeling positive or negative.
