Bug in main.asm when a char is encrypted to '\0' (NULL char)

[MostafaSaad7]

BUG in main.asm

main.asm have a bug: When a char is encrypted to '\0', there is a problem happens when we copy teaOut to teaIn again for decryption because Str_copy copys characters till it finds a '\0' so the teaOut is not fully copied back to teaIn in this case.

Failed test case:
input: MACBETH. My dearest love, Duncan comes here tonight. LADY MACBETH. And when goes hence? MACBETH. Tomorrow, as he purposes. LADY MACBETH.
Enter Key 1: 7
Enter Key 2: 8
Enter Key 3: 9
Enter Key 4: 0

I solved this bug by replacing how teaOut is copied into teaIn

Replaced

; teaIn = teaOut //copy teaOut in teaIn
lea eax, teaOut
lea ebx, teaIn
INVOKE Str_copy,eax, ebx

in main
to

; teaIn = teaOut //copy teaOut in teaIn
mov ecx, newSize
lea ebx, teaOut
lea edx, teaIn
copyLoop:
mov al, [ebx]
mov [edx], al
inc edx
inc ebx
LOOP copyLoop
