Whilest implementing merge sort, i had to create a function that copies an array into another one. Something went wrong, though. At first my code looked like this:



void printArray(int *a)
{
...

I have a base class "Artikel" and a couple of derived classes "AudioCD" and "Boek"

Then I have a class "Winkel" that has a private member ArtikelLijst* stok. Stok is the head of a linked list that...

thank you for the reply guys, i was compiling it like this
g++ *.cpp

what flags do i need to set to have the same behavior as C's gcc -ansi -Wall -pedantic?

also laserlight, could you tell me...

first of all, how come you can do this in C++ and not in C

int a[n];

secondly, why is the array "a" being printed after i freed it in the following piece of code:

int *a = new...

Say I have a class Pawn with a constructor Pawn(enum colors {white,black} Color).

Now, somewhere else in my program, I have to make a 2D array of pointers pointing to pawns.

First of all, how...

For example:

int a = 5;
int &b = a;
++b;

b and a are both 6

on wikipedia i read about these types, but is it possible to declare and use them in C?

oh god :) thanks hahaha what a stupid mistake :)

Can anybody see why the following piece of code does not provide the correct output for the calculation of the sum of all primes < 2 000 000?


#include <stdio.h>
#include <math.h>
int...

oh thank you very much :) thought it was part of stdlib..
how come i can compile atoi but can't compile itoa lol :D

does anybody know why this piece of code is not compiling?


#include <stdio.h>
#include <stdlib.h>

int palindromic(int number);

int main() {
int greatest = 0;

For those interested, this is very clean and short

__int64 number = 317584931803;
int divisor = 2;
while (number > 1) {
if (0 == (number % divisor)) {
number /= divisor;
divisor--;...

Lol, I replaced numb / 2 with sqrt(numb) and it found a solution within a second :)
I should have thought about that... Thank you for all the help.
And nice work, bernt. I just started today, this...

Well it is for this problem:


The prime factors of 13195 are 5, 7, 13 and 29.

What is the largest prime factor of the number 600851475143 ?

My isPrime algorithm:

int isPrime(unsigned...

You even tiny url'ed it.
I've googled it before I came here.

i am looking for the most efficient way to check wetter an integer is prime or not

When I try to check the size of an array that is allocated, it always tells me the size is 8, no matter how many bytes I allocate. When I check the size of an array that is declared the normal way,...

Thanks for all the response, Salem's in particular.



I was acctually doing a matrix project to refresh the pointer notation ^_^

void PrintMatrix(int **matrix, int rij, int kolom)
{
int i, j;

printf("Resultaat: \n");

for (i = 0; i < rij; i++)
{
printf("[");
for (j = 0; j < kolom - 1; j++)

I think it was pretty obvious I wasn't talking about the MAC-address lol
Thank you for the reply!

Hello

Yesterday, I installed GTK+ on my macbook pro and I wanted to download Glade via macports (sort of synaptics for mac) but I stopped in the middle because I had to go. Now some files are...

yes i know but i mean without allocating. But I guess not than :) thank you

I get what you mean laserlight, you are right.
But isn't there a way to give a value to a char pointer that isn't pointing to anything? I really thought there was a possibility to do this? Just...

yeah i used gets for a quick example

i also thought you were able to declare a string like char *conststring; and then give it a value via gets() or fgets() or what ever, but you just werent able...

when you declare a string lets say

char *string;

can you give it a value? fe: gets(string)
or can you only use it as a const string like

char *string = "blabla";
