| | Hi, I wrote [URL="http://www.daniweb.com/software-development/cpp/code/363562"]this C++ article[/URL]. 1. At first I thought of making it a tutorial, but when I create a new post there is no option in the combo to say it's a tutorial. Only options available were discussion thread and code snippet. I was hoping to get an … |
| | You can use sed or awk. Perhaps awk is more readable if you're new to shell scripting. Create one RE each for ID, PA, PT and Sequence. And in the body print the output. something like: [CODE]awk ' /^ID / { print $2,";" } /..../ { print ... } '[/CODE] … |

| | This article shows you how to optimize memory allocations in C++ using placement new. Applicable especially to usecases dealing with creation of large number of objects. [COLOR="Red"][B]A brief on problem:[/B][/COLOR] Lets take example problem for simplicity: - I have a GSM network with a cell in it. - Cell's coverage … |
| | Hi, I have a problem where I need to generate hash for ~10e9 (1 bio) keys. I tried creating a hash of my own but after all the research I realized that I can as well (or even should) use one of existing functions. I narrowed down on SHA-1, which … |
| | [CODE]for (i in name) { printf("%15s %21.2f\n", name[i], sales[i]) | "sort -nr" }[/CODE] In this i is set to each "value" of the array element and not the index. There is no simple way to find the array size in awk. Some newer versions of gawk, nawk support it. So … |
| | What if you hardcode the key inside the script and then [URL="http://linux.koolsolutions.com/2009/01/20/howto-encrypting-a-shell-script-on-a-linux-or-unix-based-system/"]encrypt the script itself[/URL]? Given that shell script itself is not human readable anymore, your key is safe. Downside is that every change in script would need to you to re-encrypt it. |
| | Did you check details using -d option? clearmake -d "whatever other options/params you used" |
| | Problems are not related to the variable being global. It's the size if it and whether it's null terminated or not. read the documentation of gets() to see what it expects as the argument and what happens when user gives more chars than the size allocated for the string passed …  |
| | Can you post the exact command line you're using to compile along with compiler errors exactly as reported? |
| | What kinda application is this? JSP/Applet/..? When / where do you want to show the tally? On some button click as a msg box or continuously updated in some text area in the UI? |
| | Arrays are passed by reference. Your problem should be with the second function (not passing the single object by ref/ptr). |
| | Also line 7: don't use variable names that sound like proper commands.. by default make it a habit to prefix/suffix "my" or something else to all your variables.. "file" is a command. |

| | What's the problem? I don't see where are you attempting to print the contents as hex. You should probably not use readLine(). Use any variant of read() instead it returns a single char (or specified number which can be 8 or 16 or 32 depending on how you want to … |
| | Re: Makefile error Works fine for me.. with GNU Make 3.81 Two guesses: 1. You have spaces instead of tabs. 2. Your new-lines in Makefile are in wrong format (DOS or Unix). Run dos2unix or unix2dos. |

| | Hi, I was implementing the Exampler / Prototype pattern just to brush up on C++. Couldn't figure out how to do the cleanup at the end. Problem is deleting all the prototypes from the map in base class at the end. I.e. deleting all stored pointers in [ICODE]Animal::examplesPtr[/ICODE], which is … |
| | Hi, I want to get the count(*) from all tables under a schema. How to can do this using a loop? I'm a noob at PL/SQL. I'm unable to find how to use the loop variable in the select statement. Here is what I've tried so far: [CODE]spool $DD/get_oid_dump.log; SET … |
| | Re: rm -r say yes Use rm -f instead.. To check whether rm is aliased or not use [ICODE]which rm[/ICODE]. To stop shell from resolving aliases use "\" at front, i.e. [ICODE]\rm[/ICODE] would not resolve an alias if rm is aliased. Also the following works (not a good idea in this case but you learn … |
| | Don't use [URL="http://www.google.com/search?q=csh+bad+scripting"]csh for scripting[/URL]. If you're using sh or bash, syntax is available in [iCODE]man test[/iCODE]. PS: There is no difference between a char and a string in shell. So forget the single quote for single char. It's always double quote. |

For example : [code] #ifndef SONG_H #define SONG_H class Song{...} #endif [/code][/QUOTE] Why not [ICODE]$pragma once[/ICODE] instead? @OP: Most probably the issue is you're not linking your client's .o file with Song.o while linking.

| | You've posted the question in C forum so I guess you're using a C program. The code shouldn't have compiled in the first place as the symbol has namespace in it, viz not supported in C.

| | I don't have hash_map & hash so I replaced hash_map with map and removed hash. It seems to work though there seems to be a small problem with printf(). What I suggest (to debug this further) is to create default and copy c'tor for your struct (or change it to … |
| | I doubt that using RegEx would improve the performance. If you're on ?nix, why don't you use grep? You can find what you're looking for [URL="http://www.google.com/search?q=java+regular+expression+with+a+code+snippet"]here[/URL]. |
| | 1. Although the option 2 is better from performance point of view as YOU decide exactly which statements within the method are synch'd. 2. Even the statements that access the data from underlying storage need to be synch'd. |

| | Interesting.. Can you post full code? With main()? so I can run it in my CodeBlocks..  |

| | Re: Sed help [quote]is it possible to become with only one regular expression ?[/quote] Yes. :) Did you check the "n" command in sed? It basically loads the next line into buffer. Would be useful here. Google for "sed one liners" you should find some examples you can use. |
 | Re: linker errors Can you post the linker errors? Also the command lines (from the VS build logs). --edit-- And certainly DO NOT use stdlib as the name!! As already said by Ed.. Don't post the errors unless you've changed the name. |
| | Try compiling code similar to case 2 in java. You'll get a warning from compiler saying "static methods should be invoked on class instead of object". As Mike pointed out the obvious overhead is the instantiation. |
| | Re: editing ksh file [iCODE]sed "p;s/^\(\([ (]*'[^',]*', \)\{6\}\)' '/\1'X'/g" filename[/iCODE] assumes number of spaces etc is fixed, if not put a few +s and *s appropriately. |

| | Syntax of your xml is wrong. You can't have the outermost tag twice in a file. So modified it a bit and assume that's what you want.
