Printf Alignment:

ali2011 · 07-12-2012, 04:34 PM

Is it possible to force printf in C to print a large file, from which the following is a cut to make the last column aligned as below?

PS: The lines in the file are printed line-by-line in the code.

The current printf result:

Quote:

1 104 101 37 [3]
1 25 111 [2]
1 25 58 117 [3]
1 25 58 46 126 148 123 [6]
1 25 58 46 126 [4]
1 152 129 [2]
1 25 58 143 [3]

The goal is:

Quote:

1 104 101 37 [3]
1 25 111 [2]
1 25 58 117 [3]
1 25 58 46 126 148 123 [6]
1 25 58 46 126 [4]
1 152 129 [2]
1 25 58 143 [3]

For some reason the last column in the goal file is not aligned as required when I post the file as a code; anyhow, I look for number in between the square brackets to be aligned throughout the file.

Please re-think and re-state your question.

Look at something like printf("%10s", variable)

Paste the output between code tags ([code] and [/code]) instead of between quote tags ([quote] and [/quote]).

Code:

  1  2  3
 11 12 13

1st, man printf, then you can know many format informations about it. (so you can know how to display with many different and useful ways)

2nd, when output, you can calculate the location firstly, and then output it (so you can control the detail locations)

That is all.
