You apparently have gratuitous newline codes sprinkled throughout.

The forum has removed all multiple whitespace and rendered the illustration of your problem useless.

You should use code tags for the example text output.

How are you outputting the text; with iostream or stdio?

Both stdio and iostream allow field widths and left/right justification to be specified. Something like:

Code:

fprintf( "%-30s%2.2X", characters, segment ) ;

will pad the string characters to exactly 30 characters with spaces, and display the integer segment as two hex digits.

Similar things can be done with iostream using the setw I/O manipulator: http://www.cplusplus.com/ref/iostream/iomanip/setw.html

The thing about text files is that different editors can display them with different fonts. Even if you're audience consists entirely of windows sheep running only notepad many of them may have a different system font set. You also have to take into account fixed width vs variable width fonts. You can get it looking right on your system, but remember that this may not hold everywhere.

That said, look into the iomanip library and setw() functions.

mitakeet looks a bit sheepish. Truth be told I haven't been in anything but windows for a month or so myself. I keep going back to play tactical ops.

In little bit to my defense, I work with *nix almost all day at work, but they took away our Sunrays and we have to ssh to the machines from our PC to do work. I used to have RH 8 installed on a machine at home, but rebuilt that as Win2K. My excuse? At the time I could not get the machine to talk to the 'net past my proxy. Since then I have switched to a DSL router and should not have problems, but have been too lazy.
