Question

Write a MARIE program to calculate Fib(n)

Answer 1

Answer:

MARIE program to calculate Fibonacci of any number:

Explanation:

ORG 000  

INPUT USER                              //Takes input from the user  

SUBT TWO                              //Subtracts 2 from it  

PRINT, STORE Y                     //Stores the accumulator Value in Z  

CLEAR                                     //AC=0  

                                                    //TOTAL = N1 + N2  

ADD R1                                     /Adds R1 to AC  

ADD R2                                    //Adds N2 to AC  

STORE TOTAL                    //Store to TOTAL  

                                                  // R1 = R2  

LOAD R2                            //Load R2 to AC  

STORE R1                           //Store to R1  

                                                //R2 = TOTAL  

LOAD TOTAL                          //Load TOTAL to AC  

STORE R2                          //Store R2 to AC  

LOAD Y                                 //Load Z to AC  

SUBT ONE                         //Subtracts 1  

SKIPCOND 000                 //Skip Cond 000 if AC<0  

JUMP PRINT                        //Print Loop  

LOAD TOTAL                        //Load TOTAL in AC  

RESULT                                //Display Output  

HALT                                //Halt Process  

                                              //INITILIZATIONS  

USER, DEC 0  

ONE, DEC 1  

TWO, DEC 2  

Y, DEC 0  

R1, DEC 0  

R2, DEC 1  

TOTAL, DEC 0  

Answer 2

Answer:

The value n can be assigned to determine whatever the number will be determined in the right terms of series. This would go with MARIE program to calculate the Fibonacci services and needs to assign the value of N.

It should computes with value 13 and denotes premature optimization can make program debugging more value. User inputs are taking away with program outputs denotes changes with respect to user inputs.
