Write a Program for ascending order in 8085 microprocessor?

Answer 1

Source program :

• MVI D, COUNT : Initialize counter
• MVI B, 00 : Initialize variable to store previous number
• MVI C, 01 : Initialize variable to store current number
• MOV A, B :[Add two numbers]
• BACK: ADD C :[Add two numbers]
• MOV B, C : Current number is now previous number
• MOV C, A : Save result as a new current number
• DCR D : Decrement count
• JNZ BACK : if count 0 go to BACK
• HLT : Stop.

Answer 2

LXI H, XXXXH :Memory location to store the series MOV M, 00H :Store first number of series INX H :Go to next location MOV M, 01H :Store second number of series INX H :Go to next location MVI D, COUNT :Initialize counter MVI B, 00H :Initialize variable to store previous number MVI C, 01H :Initialize variable to store current number Back : MOV A, B :Load first number in accumulator ADD C :Add two numbers MOV B, C :Current number is now previous number MOV C, A :Save result as a new current number MOV M, A :Store next number in memory INX H :Go to next memory location DCR D :Decrement count JNZ Back :If count=0 go to Back HLT :Stop.

Answer 3

• MVI B, 09 : Initialize counter
• START : LXI H, 2200H: Initialize memory pointer
• MVI C, 09H : Initialize counter 2
• BACK: MOV A, M : Get the number
• INX H : Increment memory pointer
• CMP M : Compare number with next number
• JC SKIP : If less, don't interchange
• JZ SKIP : If equal, don't interchange
• MOV D, M
• MOV M, A
• DCX H
• MOV M, D
• INX H : Interchange two numbers
• SKIP:DCR C : Decrement counter 2
• JNZ BACK : If not zero, repeat
• DCR B : Decrement counter 1
• JNZ START
• HLT : Terminate program execution

Answer 4

I made this program in C for you:

#include <stdio.h>

#include <stdlib.h>

#include <ctype.h>

#include <string.h>

#include <conio.h>

typedef unsigned long int ulong;

ulong fibonacci( ulong );

int main( void ){

int iNumber, iExit = 0;

char iChoice;

do{

system("cls");

printf( "Fibonacci serie:\n\nEnter number: " );

scanf( "%d", &iNumber );

printf("\nFIB(%d) = \n", iNumber);

for( int i=1; i<=iNumber; i++ ){

// These square brackets highlight

// the last number in the sequence.

if(i==iNumber){ printf("["); }

printf( "%#5d", fibonacci(i) );

if(i==iNumber){ printf("]"); }

if(i<iNumber){ printf(" "); } // Number separator

// Go to next line every 10 numbers

if(i % 10 0 !strchr( "yYnN", (char)iChoice ) );

if( strchr( "nN", (char)iChoice ) ){

iExit = 1;

}

} while ( !iExit );

system( "cls" );

system( "pause" );

return 0;

}

/*

Sequence:

1 1 2 3 5 8 13 21 34 55 89 ...

Definition:

FIB(0) = 0;

FIB(1) = 1;

FIB(2) =

FIB(1) + FIB(0) =

1 + 0 = 1

FIB(3) =

FIB(2) + FIB(1) =

FIB(1) + FIB(0) + FIB(1) =

1 + 0 + 1 = 2

FIB(4) =

FIB(3) + FIB(2) =

FIB(2) + FIB(1) + FIB(2) =

FIB(1) + FIB(0) + FIB(1) + FIB(1) + FIB(0) =

1 + 0 + 1 + 1 + 0 = 3

FIB(5) =

FIB(4) + FIB(3) =

FIB(3) + FIB(2) + FIB(3) =

...

... = 5

And so on...

*/

ulong fibonacci(ulong n){

if( n==0 n==1 ){

return n;

} else {

return fibonacci(n-1) + fibonacci(n-2);

}

}

I added a Pastebin link as a related link, there you'll see the code highlighted and indented.
