I know, it was declared as an array, but the variable, line, oddly enough, is treated by the compiler as though it were a pointer.

I know this was just a learning exercise, but standard programming practice is to put the file-to-string conversion into a function and make it reusable. A rudimentary example function might take a...
That's why some think it is good practice to set variables to NULL after freeing the pointer. I once wrote wrapper functions that keep track of malloc and free and take care of stuff like this, but...
If you're going to use printf, why not use printf formatted output?
#include<stdio.h>
int main (void) {
int i = 10;
int n = i;
printf ("%*s\n",i+1,"*");
while (--i) printf...
Nit-pickers will notice that the letter 't' is also in common. Free code is never guaranteed to be bug free!
I just did something like this, so the user could mix, match, and combine long and short options.
-p -q -d -t
-pdquiet -tabs
-pullq -droptabs
#define HAS(a) strstr(argv[argc],#a)

I have used the development library for ffmpeg with some success. The .MOV container is pretty simple, I think. Just some basic atoms to store audio and video. But if I were to do this again, I would...
You could also read the number in as a string of characters. Limit input to some arbitrary size and then store them somewhere convenient, like a slightly larger array of char. Then loop through and...
Pointers are variables.

Also getch(); is not defined in stdio.h and on Linux getch() only works within special curses applications that disable line...
Just use the = operator.
#include <stdio.h>
#include <string.h>
typedef struct {
char Words[88];
} UniqueWords;
UniqueWords w0={"HEY"}, w1 = {"Hello Struct Copy!"};
int main (void) {
This is how that code could (sort of) potentially work, even though I think after looking at this that it is fundamentally the wrong way of doing it. Song names can not have spaces in them, are...
Greetings and Happy Turkey Day! :)
That is a fine concept there though it has errors.
Arrays start at 0, not at i = 1.
songlist will never == NULL because the array is not terminated with 0...
You could also use an enum.
#include <stdio.h>
enum {play=1,stats,quit};
int main (void){
int input;
scanf (" %d",&input);
switch (input){
case play:
I'm not sure how much this helps determine periodicity, but here is a way to at least get the same sequence...

Hello. How is the weather? We have had 2" of snow here and a bit too cold to go out, so I decided to look for a program to write.
Is this what you were trying to do?

I imagine that a simple code breaker could also be written to attack substitution schemes like this with frequency analysis (LFQ). Then the most common letters can be printed out. A message like...
Consider a 2 x 2 grid. All possible paths from a to b would be a square.

Now just recurse :D
Sorry... I couldn't resist!
Since you said you use Linux, look at GTK+ - About
It is cross-platform and supports loading images into a click-able map.
Some boilerplate code from GtkImage:

Perhaps davidjg is in need of a pseudocode compiler :D

Good effort. :)
* malloc returns an address. You are trying to assign that to a variable of type record which is"typedef struct students" not a pointer.
* malloc uses memory which must be free()'d...
What results were you expecting? It looks like you have some parenthesis out of place. Here is the pseudocode of what I think you were trying to do (indentation is used instead of parenthesis).

Nice try! Turn on compiler warnings. It should help some. :D
standard says to use int main (void)
main must return an int
scanf can eat up whitespace before entries. try scanf " %d %d" ...

Heh, so you want to play with pcap? I don't know of any "course" that teaches man in the middle attacks. I wouldn't do it because packet inspection is so simple I would feel like I was taking...
