I suggest you take a read through The Function Pointer Tutorials (http://www.newty.de/fpt/), particularly this one (http://www.newty.de/fpt/fpt.html#r_value).

I would use some typedefs to help:
...

Sorry to respond to this late... but I wanted to post info also...

The getline() function has the obnoxious habit of returning a not good() stream for final blank fields...

For a single blank...

I agree with AD that the FTP is probably what is going wrong.

FTP defaults to text mode. You must explicitly set it to binary mode before copying files.

Alas, I just googled it.

Try searching for things like "bresenham line circle ellipse algorithm".

Speed comes from doing the least to draw individual pixels. Hence, a lot of optimization comes...

I just can't fathom why truly brain-dead things like system("PAUSE") keep being taught.

I can only presume it is because important things like security, process control, system resource...

Yes, you really are asking an OS and SDK-dependent question.

If you are using something like SDL, then respond to the key events that SDL gives you. Most GUI/graphics toolkits will give you a way...

Good grief. Only use TerminateProcess() to kill the unruly.

Otherwise, just ask it nicely: send it a WM_CLOSE message. If it doesn't respond in, say, 500 ms or so, use CreateRemoteThread()...

If you read and write your files one byte at a time, endianness is not an issue.

However, bit order is always an issue. The first bit you write should be in bit position 0 of the first byte you...

You need to keep track of how many bits you have "output" so far. When you get eight or more, output a byte.

unsigned char bits = 0; // the unwritten bits
int count = 0; // the number of...

Google "mingw sdl" and take a look through the first few links.

If you haven't already, make sure to upgrade to the latest version of MinGW (Dev-C++ comes with a pretty old one).

Good luck!

Yes, it is an encoding issue. I suspect that it comes from the way your editor is saving the text file.

There are several ways to 'encode', or store, character data.

There is the old char-sized...

No, it is the same as all the files having a #define GRAPHICS
To have a value:
g++ -DGRAPHICS=1 --> #define GRAPHICS 1

if (GRAPHICS) will work if and only if GRAPHICS is always defined to have...

Empty files will never do anything except exist. ("Existing is basically all I do!" --Fry)

It also sounds like there is something misconfigured with your Code::Blocks IDE. Have you been able to...

In addition, you should have a removeBook() (or some such named) method(s) for the user's convenience.

Use the STL

#include <algorithm>
#include <fstream>
#include <iostream>
#include <iterator>
using namespace std;

int main( int argc, char** argv )
{

With just a very quick glance, that notOptimized() function needs some help. A bitvector (or vector<bool>) is not a good choice in such a function. Sad, but it was optimized for space, not speed.
...

Without even looking at your code, I will make a wild stab in the dark and say that you are using a Windows console to run your program?

If you are, right-click the icon on the console's title bar...

semicolons
A semicolon by itself is considered a null statement, and has no meaning. Modern compilers will typically complain about them unless they explicitly terminate a statement. For example...

Heh heh heh -- I couldn't resist iamthwee's challenge (sorry conan --look below for where to get a dictionary).

// boggle-solver.cpp

Actually, putting that system pause in there contributed to my low opinion. You said that was an example of when he uses <cstring>.

gets() is pure evil and should be lynched at every opportunity....

How is your dictionary stored? If, like iamthwee suggests, it is a file with words in it, you can just search the file for the given word.

You can even use the STL for that:

#include...

#include <iomanip>
#include <iostream>
using namespace std;

int main()
{
for (int n = 1; n < 6; n++)
cout << n;
cout << setw( 5 ) << right << (167) << "mm\n";
return 0;

There is nothing more or less hard about C++ than any other programming language.

People fear C++ because it comes with a very large set of capabilities.

It can be used to program procedurally....

In practice it doesn't impact performance.

What it does is make your code more usable, more correct, and easier to read.

All you ever wanted to know about const correctness...

Olvidaste poner conullas al seis. while (producto != '6')

Hope this helps.

Ah, it is because seating is declared as a 2D array, but you are only indexing one dimension. Hence the error.

Did you mean to treat seating as a 1D array in your function? I'm not sure how you...

OK, I told you I'd get you an example. I don't want to spend a lot of time finding the libraries to do it and coding one, but I do have an old program I wrote many many moons ago, when I was still...

That was just an example function I created. I expected that you would take the code you needed from it and put it in your own function.

I don't think that TTextBox::Text takes a std::string, does...

If all you want is teletype output (like you get on the console, without any fancy graphics or fonts or etc) you can open the PRN or LPT1 device:

#include <fstream>
#include <iostream>
using...

A char is guaranteed to contain 8 bits, at least. (And unless you are playing with really old hardware, like ancient vaxen, a byte is also 8 bits.) But the compiler is not required to store...

Google "linked list".

I presume each node represents a single atom?

Actually it does have it backwards...

foo = this->foo; != this->foo = foo;

?

Depending on how the data is packed.

If it is packed (MSB...LSB) ARGB then

int alpha = (color >> (3 * 8)) & 0xFF;
int red = (color >> (2 * 8)) & 0xFF;
int green = (color >> (1 * 8)) & 0xFF;...

That's because you are actually creating two different types of structure.

In C and C++, arrays are something of a mixed bag.

When you declare
int a[ 10 ][ 5 ];

What is actually allocated...

Wow, I'm really surprised to see AD so boiled up over something like goto.

(I thought you were cool man.... *sniff* --- heh heh heh)

Actually, you'll notice that goto still exists in many...

Your loop encompasses both the menu and the selector, as:

do {
display_menu();
select_option();
while (!done);

So if the option is bad, the menu gets displayed again anyway.

What...

Yes, OK. Your routine should terminate when you hit one, not -1. (You've got it right for the last three clauses of your code -- the stuff handling the positive numbers.) The trick is what happens...

You are correct. The process file table and the current working directory are not modified by exec(), so the new executable inherits it all.

Of course, once you get the whole line, you'll want to parse it using a stringstream and getline() again...


#include <algorithm>
#include <iostream>
#include <sstream>
#include <string>

IMO, interfacing with the user is one of those things that needs to be absolutely bullet-proof.

There are two things to keep in mind here:

1. How does the user expect to interact with your...
