On the assumption that you're using Turbo C, please make sure that your linker settings include the graphics library.

Have you considered a loop? That's generally how we repeat things in C. ;)

How many threads are you going to start asking essentially the same question?

[QUOTE]I'm getting a error msg: 'cannot convert sprites* to sprite_data** in assignment'[/QUOTE] Your name choices are confusing you. [ICODE]blocks[/ICODE] is defined as being a pointer to [ICODE]sprite[/ICODE], which the error suggests is a typedef for a pointer to [ICODE]sprite_data[/ICODE]. This is very different from the [ICODE]sprites[/ICODE] typedef, which is a …

[QUOTE]can i request the moderator to delete an thread i've posted?????!!!!!![/QUOTE] Feel free to report the thread (use the Flag Bad Post button) along with a reason for why you want it deleted/edited and we'll review it. You can always request moderation of any kind, but unless there's a clear …

I may have a slightly better idea. Instead of making the new thread button more prominent, how about placing a date check script on the reply buttons? If the thread is older than N days, a nuisance popup could be used. The popup would give posters the option of creating …

Links in your signature do not by themselves count as spam. It's only if you post with the sole intention of promoting your signature that they count as spam. This is a difficult pattern to nail down accurately, so if you have links in your signature, you might find otherwise …

[QUOTE=Lordvivi;1656616]You can also use this [CODE=c] scanf("%c",&aChar); fflush(stdin); /*It clears the input*/ [/CODE][/QUOTE] No, it's wrong because fflush() is only defined for [U]output[/U] streams. Just because it happens to work for you doesn't mean it's correct.

[ICODE]i[/ICODE] and [ICODE]j[/ICODE] will never be equal when the item count is even. You're swapping both halves of the array in that case, which ultimately produces the original sequence. Perhaps instead of using that weird logic for your swapping loop, just use the relationship of [ICODE]i[/ICODE] and [ICODE]j[/ICODE] as the …

Find an area with free Wi-Fi. For example, in the United States it's hard [I]not[/I] to find commercial areas (McDonalds, Starbucks, etc...) that offer Wi-Fi as a free service to attract more traffic and hopefully sell product as a result.

Forgive me if I'm confused, but from the look of your code, you should be well aware of how to calculate the mean from an array (I assume you're talking about the arithmetic mean): [code] #include <math.h> #include <stdio.h> #include <stdlib.h> #include <time.h> #define N 50 double mean(int a[], int …

[QUOTE=marirs07;1656111]offsetof cannot be used in this case because u dont know the member's name but only the address of that member :([/QUOTE] Whoever gave you this exercise is either mistaken that it's possible, or expecting a non-portable hack. Either way, you need to get clarification, because within standard C there's …

Academic purposes or not, information on exploiting buffer overflows constitutes hacking, which is against Daniweb's rules. I'm sorry.

You won't find a book with complete details, the topic is far too broad.

[QUOTE]i ask this cuz i'm not sure if it's worth learning to use command line arguments or not[/QUOTE] Command line arguments are very simple and worth knowing.

If you can suffer the extra storage cost while building the tree, place all of the pointers into an array initially, shuffle the array randomly, [i]then[/i] do the insertion: [code] { std::vector<mesh_t> v(62500); std::fill_n(v.begin(), v.size(), next_mesh()); std::random_shuffle(v.begin(), v.end()); for (auto mesh : v) tree.add(mesh); } [/code] Given a basic binary …

[QUOTE]Your instructor will get there eventually.[/QUOTE] If he's lucky. More likely is that his instructor will go through the gamut of lower level and error prone C-style solutions, and only mention the "STL" in passing.

>Can't seem to figure this out. You're not the only one. There isn't a portable way to get the size of a dynamically allocated array. You need to pass the size to your function: [code] void addNodes(string names[], size_t size) [/code]

There's no prototype in scope for simple_readline() when you use it, and the arguments you provide, while compatible, don't exactly match the definition. The fix is to add a prototype for simple_readline() before main().

That's a very roundabout way of saying you want to validate login credentials. ;)

Good guess. :)

[QUOTE]Basically the time old question of who would win.[/QUOTE] Including the time old mistake of no context. Language comparisons without context are pointless.

Note that simply posting a homework assignment is against our rules. We require that you show some effort in solving the problem yourself.

Comparison is done with [ICODE]a == b[/ICODE], assignment is done with [ICODE]a = b[/ICODE].

[QUOTE]Can anyone see what I am doing wrong?[/QUOTE] Yes, and I can illustrate the issue in a test program for you: [code] #include <stdio.h> void reset(int value) { value = 123; } int main(void) { int x = 0; reset(x); printf("%d\n", x); return 0; } [/code] [ICODE]value[/ICODE] is a copy …

You haven't provided sufficient details about the software requirements. What is "progress"? What information are you logging? How will the logs be used?

[QUOTE]I need recommendations on a good C book.[/QUOTE] For what purpose? Do you need a good reference? A good beginner's tutorial? Advanced topics? Algorithms and data structures using C?

Are we talking about the full range of int, or just the ten decimal digits? The latter is trivial while the former is not.

Show me yours and I'll show you mine.

Um...what? Your question isn't clear, please try again.

[QUOTE]How could I make the input (password) invisible?[/QUOTE] You probably don't really want to make it invisible because that's not as user-friendly as it could be.

Here's one possible implementation of diwakar's algorithm: [code] #include <ctype.h> #include <stdio.h> int is_finished(void) { char line[BUFSIZ]; fputs("Again?

[QUOTE]I am aware that it can be a slow programming language[/QUOTE] Any programming language can be slow in the wrong hands. Java is notorious for being slow not because it's actually slow, but because it's accessible. Java is easy to learn and it's easier to write complex software without a …

Strong bump. I doubt the OP is still around after seven years given his single post.

>why is it static? Primarily so that the JVM doesn't have to instantiate your controlling class to get an entry point into the program.

get/set methods should be used judiciously. As it is, you could simply make your members public, remove the get/set methods, and the effect would be the same with less code.

The language you use is irrelevant as long as it has sufficiently low level access to hook into the necessary information. Traditionally, C, C++, and assembly language have been used for exploits, but I've seen (and written) successful exploits using higher level languages. It's all about having enough power to …

Provided you don't have to deal with a true CSV format with quoting rules, parsing the file is trivial: [code] #include <stdio.h> int main(void) { int value; while (scanf("%d", &value) == 1) { printf("%d\n", value); if (getchar() != ',') break; } return 0; } [/code] Is this what you were …
