Code colouring

    /*Split from question about a working linked list ~ kenfitlike*/

    It is just your code, but painted:
    Code:
    #include <iostream>
    using namespace std;
    
    struct node {
      int x;
      node* next;
    };
    
    void createList( node* root, int size ){  //Creates a list of any size
    
      for(int i = 0; i < size; i++){
        root->x = i + 1;
        root->next = new node;  //Creates a new node at the end of the list
        root = root->next;  //Moves to that node
        root->next = 0;  //Sets the end of the list at the current node
      }  //for
    
    }
    
    void cleanList( node* root ){  //Clears the list from memory
    
      if( root != 0 ) {
    
        while( root->next != 0 ){
          node* temp = root;  //Assigns temp to be the current head
          root = root->next;  //Moves the head to the next element
     delete temp;  //Deletes the temporary head
        }  //while
    
      }  //if
    
    }
    
    void displayList( node* walker ){  //Displays all the elments of the list
    
      while(walker->next != 0 ){
        cout << walker->x << endl;
        walker = walker->next;  //Moves to the next element
      }  //while
    
    }

     // beginning, the middle or the end
     // of the list

    // node, then:

        search_ptr->next = newNode;  //Search_ptr is now the last element in the
     // in the list, so we make the next pointer

    Thread hijacker . . . .

    How does your program handle this?
    Code:
    printf("hi");
    
    #define /*what?*/ foo
    
    puts("\\\"");
    
    in\
    t x;
    
    printf("/*comment*/");
    
    /* int x; printf("int x;"); */
    
    // /*
    for(;;){}
    //*/
    
    /*//*/ int okay;

    I don't have a compiler on me ... what does it do? How does the #define with the /**/ handle? I'm assuming you're talking about the color coder (go for this one. It's much better Color Coder v2.0 (C++).) rather than the linked list forgot the oftopic tags

    [offtopic]How does your one handle it, dwks [/oftopic]

    I was suggesting that siavoshkc try that in his code colouring program.

    codeform handles it pretty well, but not perfectly. It's still a work in progress.

    go for this one. It's much better Color Coder v2.0 (C++).
    Are you kidding?

    New version, less "undocumented features"!

    EDIT :: fixed terminology, thanks dwks

    Really.

    I posted the code into the colour coder you mentioned, and it locked into an infinite loop.

    At least codeform just messes up, it doesn't freeze my computer.

    EDIT :: fixed terminology, thanks dwks
    You're welcome. Now they're documented features, eh?

    Well, that's a pretty nasty bit of code, lets be honest. I messaged the code to the maker. You're just mean, dwks!!

    I've never made a linked list. Never saw the point with vectors and lists anyways. I'm thinking I may try though ... :/ not sure if it's worth the time though. It's not gonna be as good as the STL


    [OT]>> Now they're documented features, eh?
    Well, of course not!! Have you seen documentation detailing them?[/OT]

    Yes, actually. Somewhere I saw something like "it may lock into an infinite loop, allocating memory infinitely. If this happens, quickly launch task manager by right-clicking on the taskbar, find Color Coder, and click on end task." Really. I'm not kidding. And the source code isn't available for it, so we can't help fix it.

    [edit] Yes, from the readme.txt:
    Please do NOT ask for the Source Code. This is not an opensource project.

    [...]

    If program seems to crash, CTRL + ALT + DEL and end process "Color Coder v2.0.exe", or it will grow in size very fast until it exhausts all of your physical and virutal memory. May cause PC to be extremely slow and/or crash when all of memory is exhausted.

    I'm impressed. Semantic, as I said on your forums! (perhaps we should stop talking off topic ... the OP may still need to lean something and wouldn't want to get the topic closed :/)

    Okay, agreed. Sorry, Martin. [edit=2] Martin wrote Color Coder: http://martin.thejefffiles.com/About.html [/edit]

    [edit]
    How does the #define with the /**/ handle?
    The preprocessor strips comments before it handles preprocessor directives such as #define. That's why this is valid:
    Code:
    #ifdef WIN32
        #include <windows.h>
    #endif  /* #ifdef WIN32 */

    I didn't mean that against codeform, BTW

    This probably goes under the category of 'lame', but here's a web based version if it's of any interest (not nearly as advanced as dwks's, but it could be worse).
