It's certainly possible, how do you think the operating system itself works? ;) However, without the aid of an OS, you might find yourself writing a lot of plumbing to work directly with the hardware.

[QUOTE]Now, would this work?[/QUOTE] What an odd question. Why don't you write up a quick test to see if it works? If it does, then try to break it with pathological cases.

Let the hazing begin! :D

0xabababab looks like debugger fluff for an uninitialized pointer.

If you use a console application, that will use the console subsystem. If you use a windows (win32) application, a console won't be created for you and your GUI will load alone. I don't recall off the top of my head if Code::Blocks has win32 project templates, sorry.

>People did any of you come across good tutorials on hash tables??? No, I never came across a good tutorial on hash tables. So I [url=http://www.eternallyconfuzzled.com/brain.html]wrote one[/url]. :)

[QUOTE]is that allowed?[/QUOTE] It's usually wise to ask that question [i]before[/i] starting your thread and having it shot down with an infraction. And no, as the infraction PM you received clearly states, advertising your services constitutes spam.

[QUOTE=pseudorandom21;1579352]Not to promote the use of alcohol, but it is in most places legal at least. Well I turned 21 a few months ago, so I'm wondering what everyone else drinks when relaxing on their off days?

[QUOTE]Is it even possible to create a singly linked list using a function outside of main and then access it once you leave the function?[/QUOTE] Um, yes. If that weren't possible, linked lists in C would be rather useless, no? [code] #include <stdio.h> #include <stdlib.h> struct node { int data; …

[QUOTE=coril;1626152]By error, I should have been more specific, it compiles but when it runs, it doesn't work as intended (skips the next scanf()). getchar() also solves the problem.[/QUOTE] Which doesn't invalidate the advice to avoid calling fflush() on input streams. getchar() solves the problem as well, but you might consider …

Barring an off-by-one error in your array indexing, it works fine on my end.

[QUOTE]cuz worst case it requires n swaps for each of the n elements[/QUOTE] How do you figure that?

What's the purpose of this program? Knowing the use cases can help greatly in figuring out what strategies would work best for locking down functionality.

[QUOTE]I'm not trying to write a computer virus, or trying to learn how to crack software illegally![/QUOTE] That may not be [I]your[/I] intention, but this is a public forum. How can you guarantee that what you learn in this thread can't be taken by others and used for malicious purposes? …

[QUOTE]Yes, the obvious answer is, "take as much of the most valuable powder as he can"; yes, but how do you determine that, mathematically?[/QUOTE] Is there a variable for powder value, or are you simply using size?

Can you post a more complete example that still throws your error?

Parse errors can be confusing, but if you posted your code exactly as it is, the declaration of open_file() in your header is missing a semicolon at the end. Since headers are textually inserted into the translation unit, this [code] #include "functions.h" int open_file(int argc, char argv[], int count) { …

[QUOTE][CODE]num = atoi(word.c_str());[/CODE][/QUOTE] I realize you didn't compile or test, but atoi() is declared in <cstdlib>, and it's in the std namespace. I assume you're using Visual Studio because it's pretty lenient about requiring namespace qualification on the C-inherited library. On a side note, atoi() is evil. Unless you validate …

How does your loop end?

[QUOTE]Is "ip is a pointer to int" (the type) or is "ip a pointer to an int" (a particular variable of type int)?[/QUOTE] If you want to get specific, "ip is an object with the type pointer to int". An object has a type. The object is a concrete entity …

[QUOTE]looks like c could make generic programming come true but it could be very tedious[/QUOTE] Not to mention type unsafe, which you can assign evilness to according to your beliefs about type safety. ;) [QUOTE]and much more harder to maintain than template[/QUOTE] Clearly, which is why templates were added to …

You completely failed to answer the question, or solve the stated problem, and you didn't fix any of the other problems …

[QUOTE]Couldnt this have been made much simpler if[...][/QUOTE] Yes, it could have. But like many features with the label "nice to have", the critical mass necessary to get it into the language specification wasn't ever reached. You might find a compiler that supports something along these lines as an extension …

[QUOTE]Since its the same file, we dont have to do a #include"samefile.h"[/QUOTE] Since headers provide declarations, and the extern declaration already does that, including a header at all is unnecessary. You can still have two files: [code] /* foo.c */ int a = 20; [/code] [code] /* main.c */ #include …

[QUOTE]I want the child class to overide it such that when the parent calls setupBuffer() it calls the child's version.

Given an array [ICODE]a[M][N][/ICODE], [ICODE]a[i][j][/ICODE] is logically equivalent to [ICODE]a[i * N + j][/ICODE] if the dimensions are stored in sequence.

You're entering the realm of concurrency. For example, you might create one thread to handle user input while another handles the timer.

Did you include ? Do you have a using directive for std using namespace std; or a using declaration for each standard name using std::cout; using std::cin; at appropriate locations?

[QUOTE]is it possible to have a back() in stack....i know queue and vector has it...[/QUOTE] For the standard container adapter, no. Check any reference and you'll see that the exposed non-boilerplate methods are push(), pop(), top(), and empty(). However, std::stack is an adapter for an existing container (the default is …

Sorry dude, but we're not sympathetic toward people who go through N years of school and still can't come up with a something as trivial as a [i]topic name[/i]. One has to work really hard to be that helpless.

[QUOTE]Anybody have experience in learning from video tutorials?[/QUOTE] I haven't seen any that were worth a damn.

When it comes to alignment, just play with the different setw() values until you get what you want. Alternatively, you could show the votes horizontally instead of vertically. That simplifies a lot of things.

[QUOTE]The "new" doesn't execute until absolutely necessary.[/QUOTE] That would be difficult to implement in any useful manner. Perhaps you're thinking of lazy initialized objects? That has the behavior you're talking about, but it's a part of the class implementation rather than the compiler.

The good news is that your case is pretty trivial because firefox supports command line arguments. So you can simply invoke a command line string: [code] #include <cstdlib> std::system("firefox.exe \"http://www.daniweb.com\""); [/code]

[QUOTE]So what you're saying is you defined d as a global variable of some indeterminate type[/QUOTE] Though there's a good enough chance of it being [ICODE]struct tm[/ICODE] that you can safely make that assumption rather than acting like a pedantic douche. ;) [QUOTE]changing gets() to gets_s() is a bandaid rather …

What you probably want to do is accept any character in the loop, but only print it if it matches the criteria: [code] while (cin >> letter) { if (is_vowel(letter)) cout << letter; } [/code] Obviously this is a non-working example that you would need to flesh out (such as …

I'm somewhat confused about this design. Why make CWorker's constructor a friend of CCar when you can simply construct a new CCar?

If I'm reading your post correctly, you want to change how the watch window in your IDE shows arrays? I'll go out on a limb and say that you're SOL unless you want to write a plugin to alter the behavior.

Yes, someone can help you.
