  • Preprocessor #if directive

    - by Caslav
    I am writing a big code and I don't want it all to be in my main.c so I wrote a .inc file that has IF-ELSE statement with function and I was wondering can it be written like this: #if var==1 process(int a) { printf("Result is: %d",2*a); } #else process(int a) { printf("Result is: %d",10*a); } #endif I tried to compile it but it gives me errors or in best case it just goes on the first function process without checking the var variable (it is set to 0).

  • preg_match_all with surrounding data

    - by user323304
    Hey. I have a large amount of log data that I need to get some relevant information out of. The syntax is: WORD1 some text KEYWORD some text WORD2 WORD1 some text KEYWORD some text WORD2 WORD1 some text KEYWORD some text WORD2 WORD1 some text KEYWORD some text WORD2 Would it be possible to use regex to get a certain block out of it - so that when I queried some keyword it would return WORD1 some text THIS_KEYWORD some text WORD2 PS: There could be multiple instances of one keyword, it should return all of the blocks (preg_match_all, PREG_SET_ORDER?).

  • Is there anyway to "probe" a method in common lisp

    - by Michael Minerva
    My application allows the user to create their own methods indirectly and I later need to refer to these methods. I am wondering if there is a way (for error checking purposes) to test if a method exists without trying to execute it. If I just try and call the method and it doesn't exist this will crash my application.

Secondly, will the errors affect my SERP ranking? ie, will me fixing these errors as good as I can increase my Google search position? Thanks

  • C/C++ definitions of functions

    - by Vit
    Yesterday, I have been watching discussion here, about compilers and linkers. It was about C library function definitions. I have never thought of that, so it inspired me to do some searching, but I cannot find exactly what I want. I wonder, what is the smallest syntax you need to add into your source code to enable just printf() function. I mean the function declaration from stdio.h you need.

  • PHP: Check if it has been one week since timestamp

    - by Rudi
    Hi guys, Let's assume: $time = '2010-05-17 02:49:30' // (retrieved from MySQL TIMESTAMP field) How do I do the following in PHP: 1) Check if it has been more than one week since this time has passed? 2) Assuming "false" on (1), find out how much more time until the one week mark, rounded to days and hours remaining. I know this is pretty straightforward, but it uses a very specific syntax. Having never played with time calculations before, I'd appreciate some guidance. Thanks!

  • In Java, is there a way to write a string literal without having to escape quotes?

    - by Matthew
    Say you have a String literal with a lot of quotation marks inside it. You could escape them all, but it's a pain, and difficult to read. In some languages, you can just do this: foo = '"Hello, World"'; In Java, however, '' is used for chars, so you can't use it for Strings this way. Some languages have syntax to work around this. For example, in python, you can do this: """A pretty "convenient" string""" Does Java have anything similar?

  • How do I use multiple precisions in prinft()?

    - by Tommy
    Looking at the information under the heading "Precision can be omitted or be any of:". The example: printf("%.*s", 3, "abcdef"); works, outputting:abc (truncating the rest of the string.) Now, I would like to have a string with multiple parameters formatted (truncated): printf("%.*s", "%.*s", 3, 3, "abcdef", "xyz123"); but the program crashes. What is the correct syntax? Thank You.

  • Source Code Browser

    - by James Fielding
    Hello I'm looking for a piece of relatively simple software to browse large C++ project. What I would like is something that is somewhere between a simple text editor and a full-blown IDE like Eclipse. I would like syntax highlighting, a way to see all classes/methods defined in a file, a way to find where a particular method is called from and where a variable is declared/defined. Any ideas? Thank you!
