Re: [Dev-C++] random line from file

[Per W. <pw...@ia...>]

Oooh. Lots of code, and memory intensive if the file is really big.

Simplest solution:
Read through file - count lines.
Generate a random number based on line count.
Rewinde file.
Read until nth line.

Faster solution for large files, but not completely random:
Check file size.
Generate random number based on file size.
Seek to specified position.
Scan to next newline and return next line.
Since this algorithm may never return the first line, either add special
case that random position 0 doesn't need to read past a newline character
before returning a value, or add a filler line first. Also - be prepared
that too large random number will read past last line.

If max line length is known, the second solution may be modified to
reading a block of text around the random position. If max line length is
100, load 100 characters before and after random position. Then scan
backwards to start of line and return.

No need to fight with Windows API unless speed is absolutely imperative,
i.e. normal c/c++ file operations are quire ok to use.

Here's basically what you want to do:

1. You should probably read the entire text file into memory.
2.  Treat each line in the text file as a string.
3.  Load each of these strings into a vector of strings.
4.  Then you can grab a random number from 1 to the size of the 
vector to grab a random line.

That's the basix of what you're going to have to do.

However, if you're going to have to do this through windows, you're 
going to have to learn how to get input and output working with the 
API.  There are several Windows tutorials out there that can help you 
do that.  Take a look at:
http://freespace.virgin.net/james.brown7/tutorials.html
http://www.foosyerdoos.fsnet.co.uk/

Although there really are a ton of tutorials if you just search for 
Windows C++ tutorial.

[Dev-C++] Fw: Function(name) unknon in Backtrace

[<at...@su...>]

hi there,

I'm just circling around the same error, maybe you can help me by telling
how to interprate the last entry in the backtrace:

Function        Arguments    File    Line
??                 ()                            18536      |-> no idea
.....

I think the line will be one of the wxWindows. Sometimes I get the
information, that the
headerfile just got 260 lines, but MingGW likes to go to line 516, end of
file, and so on...
I would just need the functions name to locate a segmentation fault, but the
code is difficult to debug, because of macros.
Or may a macro be the ??-function?

Using Dev C++ 4.9.8.7 on 2K, running wxWindows

thanx,
achim

gcc must have the following layout to find it's own stuff automatically:

<gcc-install>/
   /bin         - gcc.exe, etc.
   /include/    - stdio.h, etc.
     /c++/      - NO files
       /3.2.3   - (<- OR similar) iostream, etc.
     /ddk       - ...
     /GL        - gl.h, etc.
     /readline  - readline.h, etc.
     /sys       - time.h, unistd.h, etc.
   /lib         - libstc++.a, etc.
   /mingw32
     /bin
     /lib
       /ldscripts

Re: [Dev-C++] run gcc from command line

This may not be helpful either but have you looked at the 
Tools->compiler options->directories menu item to see what the dev-c++ 
directories for header and library files are?  It might help to add an 
explicit -I <path> command option for each header directory dev-c++ uses 
and a n explicit -L <path> command option for each library directory.
