I just let the argument name out. In the case I want to keep it in anyway, I define a macro:
#define UNUSED(x)
Then I would do:
data_free(void *event_data, void * UNUSED(client_data))

Then I would do:
data_free(void *event_data, void * UNUSED(client_data))
I'd say that it is used to avoid a compiler warning about client_data not being used. However, there are much simpler and beautiful approaches to that...
You only get a floating point result if your operands to the division operator are floats themselves[1]. So:
(((float)AddCountRight) / ((float)TotalAddProb) *100.0f)
See if that works. It...
I only looked at the 10 last lines. Don't you think that it will return false if you never effectively look for '/' or '.' in the string? You're basically comparing the ASCII values of those two...
I guess it means that you ask the user to enter a number and check if it really is a number, so say that:
But I could be misinterpreting... Though I don't get the name of the function... Note...
Meh, here's how I would do it:
#include<iostream>
using namespace std;
int main() {
int num=3, checknum, remainder, answer=1;
do {
checknum=2;
Well then, edit your first post and try to do your best, please. Indent how you like, but code tags are mandatory (haven't you read the forum post that talks about that? You know, the one with that...
Please!...My eyes hurt!...Indent your code!! Put code tags around it!
Hurry, I think I won't survive it...
It really depends, what error/mistake are you talking about?
1. If you're going to point to a double, use a pointer to a double (double* myDoublePtr).
2. If you're going to screw it up anyway,...
I get what you mean. Maybe some form of IPC?
If not, check this (old) article, it may be useful:

I haven't read your code in detail yet. Like you said, execl replaces the current process image, which means that nothing past execl will be executed, unless it fails. It's similar to "invoking a...
On Unix-y systems, you can run your script with one function of the exec() family (for instance, my favourite, execvp()) and then you can use wait() (or waitpid()) to get the exit status (return...
Why not try CodeBlocks with its bundled MingW or with a downloaded MingW? It's Open-Source and it has very good features. These days I'm all QtCreator, though.
I've heard the term signature when talking about calling conventions or when talking about the output of CRC32, checksum and other similar algorithms applied to the whole or portions of raw binary...
Thinking about it, I can see a possible theory -- which may be severely flawed given that I have many questions.
Say you have a Base Application.

Sorry to but in, but I have to agree.

May I suggest getting used to running your code through valgrind? It'll help you spot many of these errors, I love it! With all the modifications I mentioned, your code resulted in perfect crash-free...
There's probably an easier way to do it, but I couldn't find it.

First, don't split a string ("this is a string") across lines.
Second, if you're printing a string, it should "Look like this", and not ""like this" or "like this "" " " " " " " " " """

I see two (or three, it really depends on repetition) things wrong with your code. I believe that you should be able to see them for yourself.
Throw ideas at the forum wall.
Ah, you're right, dword-by-dword or qword-by-qword indeed, it's faster. However, I think that we should rely on the fact that our compiler produces fast code for those operators (and it probably...
Yes, NASM is the thing.
May I also suggest that you try to look at the disassembly of your C/C++ programs? Or at the output of, say gcc -S if you're with it? (or gcc -S -masm=intel).

Ah, so we're discussing if memset is in fact portable with all POD types, right?
But if we're not into arrays anymore, then what's the purpose of using memset? Using the assignment operator is...
Does it really matter all that much? If we use the {0} scheme, it gets initialized properly. If we want to see if it "hasn't been changed" we'd just compare it with (float)0, which would give you...
