Question

Microsoft Visual C++ Assembly language

Problem 3. Write a program that uses a loop to calculate the first seven values of the Fibonacci number sequence, described by the following formula: Fib(1) = 1, Fib(2) = 2, … Fib(n) = Fib(n-1) + Fib(n-2). Place each value in the EAX register and display it with a call DumpRegs statement inside the loop

For example:

Fib(1) = 1,

Fib(2) = 2,

Fib(3) = Fib(1) + Fib(2) = 3,

Fib(4) = Fib(2) + Fib(3) = 5,

Fib(5) = Fib(3) + Fib(4) = 8,

Fib(6) = Fib(4) + Fib(5) = 13,

Fib(7) = Fib(5) + Fib(6) = 21

Description: Write a program that uses a loop to calculate the first

seven values in the Fibonacci number sequence { 1,1,2,3,5,8,13 }.

Place each value in the EAX register and display it with a

call DumpRegs statement inside the loop.

Answer 1

Code:

INCLUDE Irvine32.inc

.code

main PROC

    mov   eax,1

    call DumpRegs

    mov   ebx,0   ;

    mov   edx,1

    mov   ecx,6   ; Counter set to 6

                ;loop will run 0 to 6 = 7 times to print 7 values

    LOOP1: mov eax, ebx

           add eax, edx

           call DumpRegs ;calling DumpRegs inside loop

           mov ebx, edx

           mov edx, eax

    Loop LOOP1

    exit

main ENDP

END main
