I don't care for mahe's intentions, or Salem's assumptions about them, as I post to talk about interesting things like programming. :-p
What I have found is that the call to socket fails whenever...
Please experiment with libpcap and socket, and find out for yourselves where the described security feature is implemented. It is more helpful than making hasty judgements about mahe's character.
It's system dependent and it doesn't really have anything to do with C. On Linux, I have personally taken the following approach.
#include <stdio.h>
#include <stdlib.h>
#include <arpa/inet.h>...
It is not unsafe for the caller to know what they're giving a function, it is simply unappealing to the lowest common denominator.
#include <stdlib.h>
char *insertstr(char *s, int split, const...
Consider reading about the getc and fgets functions in <stdio.h>.
Hmm ...
#include <stdio.h>
#include <string.h>
char *insert(char *to, const char *s, int split, const char *in)
{
sprintf(to, "%.*s%s%s", split, s, in, s + split);
return to;
Considering the exercise, this course seems like a rather lousy way to learn programming with C.
A different approach:
* Allocate storage for two arrays. One, an array of char (char[]), the other, an array of pointer to char (char *[]).
* Copy the whole (line?) into the first array.
*...
So long as you are consistent when you write your source code (by using either int32 or int32_t, but not both), the type name you use doesn't really matter. (There may, however, be portability issues...
char, float, and double are standard types. bool is provided by <stdbool.h> (a typedef for _Bool), and int32_t is provided by <stdint.h> if the C implementation happens to define a signed 32-bit...
The value that is stored in spoj1min is modified during each iteration, so the third line of your code snippet is equivalent to "spoj1min = spoj1min * 2", rather than the desired "spoj1min = spoj1min...
The way the function is currently defined, it will delete each element in the list that is equal to 'number' (and also, not the first element of the list.) But the name seems to imply that it will...
It can help to break procedures into multiple simpler ones. Consider the following break-down.
* Translate upper-case to lower-case characters in a string.
* Remove characters, in a string, that...
You're welcome. :-)
There are a few ways to go about it, probably the simplest is to write to a file from your program, and read from the file with gnome-terminal. The first thing to do is figure out how to run a...
I think it would be cleaner if you rewrote it so it depends less on preprocessor magic. That function definition probably doesn't need to be inside of a header, kernel_image_* probably doesn't need...
The type of 0xff would actually be int.
The point I was trying to convey is that C will interpret the integer constant (not the representation) 0xffffffff as having the value that is commonly written as 4294967295. (See 6.4.4.1p4.)
To be clear, 0xffffffff is not -1, it is 4294967295. This value may or may not be representable by an int or an unsigned int (see 5.2.4.2.1p1). When the value cannot be represented by an int,...
How about: "if (Number < array[INDEX]) (do something)" ? The thing about arrays is you can reference elements in constant time. Maybe spend some more time reading about arrays in C.
Hmm, this problem stumbled me too, but then I put spaces between each number, like: "1 2 3 4"
Then I alternated each space with a pipe, so I'd get something like: "1 2 3|4", "1 2|3 4", "1 2|3|4",...
1. <conio.h> isn't part of the standard C library. Its inclusion may introduce undefined behaviour.
2. main is defined with the type void(). This may have undefined behaviour on certain C...
Assuming that you're referring to exercises 1-13 and 1-14, you should note that the vertical histogram is presented only for those who want an extra challenge (with the 'standard' being the...
Read the program's input from a FIFO and write to that FIFO from another terminal.
In one terminal,
mkfifo outgoing
cat outgoing | nc node service
Then in another terminal,
