Write to File

[SercoSteveB]

What is the size in bytes of DataFile.txt following execution of the VI?

a) 17

b) 18

c) 19

d) Undefined (Format Into File returns an error)

1) There is no DataFile.txdt being created.

2) The answer is actually OS dependent.

For a Windows program, C.

[MrStevenUND]

To answer the question as written, E) unknown.  Depends on if it already exists.

For the question he meant, C) 19 for windows.  I don't konw about other platforms.  From help:  \n -> The Format Into File function automatically converts this code into the platform-dependent end-of-line character.

[crossrulz]

In Linux or MAC, the answer would be B.  I don't remember exactly which one uses which End Of Line value, but I know it is a single byte.

This function converts new lines, or \n, in the format string into the platform-specific end-of-line character, for example, CR/LF on Windows, CR on Mac OS X, and LF on Linux

I checked the output in Windows platform.Result is 18.now i am bit confused

C, That was great info Crossrulz...

[MrStevenUND]

Oops.  I mis-counted lastnight.  With my reasoning, it was B) 18 - 5+5+7+EOL, where EOL was just the CR.

Most of the time when I deal with manual minipulation of text strings like that, I put both the CR and LF.

From Wikipedia, here are the EOLs for each platform

• LF:   Multics, Unix and Unix-like systems (Linux, OS X, FreeBSD, AIX, Xenix, etc.), BeOS, Amiga, RISC OS and others.
• CR:   Commodore 8-bit machines, Acorn BBC, ZX Spectrum, TRS-80, Apple II family, Mac OS up to version 9 and OS-9
• RS: (record separator, 0x1E) QNX pre-POSIX implementation.
• 0x9B: Atari 8-bit machines using ATASCII variant of ASCII. (155 in decimal)
• LF+CR: Acorn BBC and RISC OS spooled text output.
• CR+LF: Microsoft Windows, DEC TOPS-10, RT-11 and most other early non-Unix and non-IBM OSes, CP/M, MP/M, DOS (MS-DOS, PC DOS, etc.), Atari TOS, OS/2, Symbian OS, Palm OS, Amstrad CPC

Answer is 18 on the Mac.

[SercoSteveB]
