Question

I need help creating this code.

Write an assembly program (MASM and Irvine's libraries) that calculates and prints out the first five Fibonacci numbers FO=0; F1=1; F2=1; F3=F1+F2; F4=F3+F2; F5=F4+F3 If we use 0, 1 and initial conditions the sequence would be: 0, 1, 1, 2, 3 Use the ebx, eax, and ecx registers. Note WriteHex, Writelnt, WriteDec, all use eax So use ebx for first and eax for second and ecx for temporary The calculation could go something like (in Java): int b=0, a=1,c; C=a; // save 2nd value into a temp a=a+b; // updata 2nd value (add 1st value) b=C // put the old 2nd value into the 1st value // repeat as needed In assemble we could do as: mov ecx, eax ; save 2nd number add eax, ebx ; calculate next number mov ebx, ecx ; mov old 2nd to new 1st call writeDec ; write eax as hex to console call Crlf ; newline ... ; repeat as needed The first two values are special (not calculated) mov eax, 0 call writeDec ; write eax as hex to console call Crlf ; newline mov eax, 1 call writeDec ; write eax as hex to console call CrLf ; newline Output should be:
