Suit yourself with what you think is necessary or even better.



I sense a hint of troll.

The value for str is always "127.0.0.1              " I'm not changing it in the code, so I'm using char *str="something" so, whether I do char *str="something" or char str[100] = "something" it wont make a difference.
As far as I know, fgets() is for input from file right(I may be wrong)? I'm using gets() as I'm taking input from keyboard.

If you're not going to change *str then why 'd you do this:
fputs(str, handler);When you do
*str = "something";
"something" is put into the string table of the executable which is read-only. Trying to write something to a r/o region is going to fail. Allocating it the other way around reserves memory from the stack which is r/w.
Use fgets with the default input stream i.e. stdin.
fgets(site, size, stdin);

Hope this helps.

I'm trying to make a website blocker that runs with administrator privileges.
Here is my C code : http://www.scriptings.tk/paste/5348fab7a1ee5
Or view it here :

Code: (c) [Select]

#include<stdio.h>
#include<conio.h>
void main()
{
   
    char* str = "127.0.0.1       ";
   
        fputs(str, handler);
     
}


The memory for str is allocated statically off the stack. It's read-only. You can't re-assign a value to it. Instead, declare it as char str[size]  = "whatever"; and it should run.
Also, always use fgets instead of gets. gets does no boundary check.

Very neat write up Kulver. Was a great read. It always appears somewhat as a disagreement to me when developing UI whether I should make it more verbose or more simple. Developers always tend to prefer verbosity, like an urge to let know what's going on under the hood. But the regulars don't want it, I suppose. So, that at times makes it hard for me to balance and then I ask somebody else (when available & applicable) to take a look and tell me what they think of it. That really helps.
And, Thank you for taking time sharing your thoughts.

These can be optimized quite a bit with things like range-for loops and more of some niceties from C++11.  Also it looks like you reimplemented std::stack? Why?

My excuse would be, I'm just learning C++. Coming from the lands of bare bones C unaware of most of the facilities it's younger sibling provides. Can you demonstrate some language optimizations you are talking about ?

struct split *stringSplit (char *str, char *delim)
{               
    char **token_array;
    *token_array = NULL;
    allocPtrs (token_array);
       
    char *token = str, *saveptr;
    unsigned int bulk = 1, j;

    for (j=0; ; token=NULL) {
        token = strtok_r (token, delim, &saveptr);
        if (token) {
            if (j == bulk*CHAR_PTRS) {
                allocPtrs (token_array);
                bulk++;
            }
            *token_array+j = calloc (1, strlen (token)+1);
            if (! *token_array+j )
                error ("calloc");
            strcpy (*token_array+j, token);
            j++;
        }
        else break;
    }

    struct split *s_arr = calloc (sizeof(struct split), 1);
    s_arr->num = j;
    s_arr->token_array = token_array;

    return s_arr;
}
stringlib.c: In function ‘stringSplit’:
stringlib.c:50:28: error: lvalue required as left operand of assignment
             *token_array+j = calloc (1, strlen (token)+1);
                            ^

The function is meant to split the string by the delimiters and return an array of substring tokens.
What's going wrong? GCC's considering *token_array+j as a constant. WHY! I'm starting to loose mental sanity

Hi guys!

This is a small mod of the classic snake game. But it's a bit more difficult than just finding way eating your food. You gotta avoid the falling blocks as well! Give it a try B)

Source and a demo video is attached. Run make and execute le_snake_mod to play game.
Cheers!
