Glad to see that my solution in the other thread worked for you. You might want to post that it worked in that thread, so people who find your thread through google know the solution worked. This forum exists for the benefit of everyone.
You're very close actually. You're not declaring the variables wrong, just using them in the wrong way.
If you want to use variables from a base class, even if you have access to them, you must still explicitly say they're in the base class. Like
When I do this for all the Sum variables you access in GrandSum, your code works fine.
Hi,
I have a base class and derived a class from the base class, i want to print & read the data for the object created for the derived class,so i have overloaded both the << and >> operators and also have done the foward declaration.
Below is the code snippet,
#include <iostream>

Hi, i have a question about C++. Is it possible to declare a class with a member ot the same class? For example, a linked list or i want to convert this C code to C++ class (Elemento)

Hi everybody
I am facing a little problem with names servers. I have a VPS with Kloxo installed on it
I have registered 2 name servers (i.e. ns1.domain.com and ns2.domain.com) past one month.
These nameservers are not accessible yet. I have check the nameserver on internic site and they are... (3 Replies)
Hello,
What is the simplest way to install CentOS 6.1 with console base-system only using official LiveDVD image on VirtualBox machine? I'd like to get simplest console with network support like FreeBSD base installation. Then, install services which I need.

Hi,
I believe the next code is wrong:
class Egg {
Egg e;
int i;
Egg(int ii=0) : i(ii) {}
};
because you would end up with an endless definition (memory allocation) of Egg objects, thus int i.
Ok, so God Eckel proposes for a singleton:
class Egg {
static Egg e;
int... (5 Replies)
Hi all!
I am trying to register a device in an existing device class, but I am
having trouble getting the pointer to an existing class.
I can create a class in a module, get the pointer to it and then use
it to register the device with:
*cl = class_create(THIS_MODULE, className);... (0 Replies)
I have the two class definition as follows.
class A { public: int a; };
class B : virtual public A{ };
The size of class A is shown as 4, and size of class B is shown as 16. Why is this effect ?. (2 Replies)
Hello All,
I am a learner in C++. I was testing my inheritance knowledge with following piece of code.

pgmtexture(1) General Commands Manual pgmtexture(1)NAME
pgmtexture - calculate textural features on a portable graymap
SYNOPSIS
pgmtexture [-d d] [pgmfile]
DESCRIPTION
Reads a portable graymap as input. Calculates textural features based on spatial dependence matrices at 0, 45, 90, and 135 degrees for a
distance d (default = 1). Textural features include:
(1) Angular Second Moment,
(2) Contrast,
(3) Correlation,
(4) Variance,
(5) Inverse Difference Moment,
(6) Sum Average,
(7) Sum Variance,
(8) Sum Entropy,
(9) Entropy,
(10) Difference Variance,
(11) Difference Entropy,
(12, 13) Information Measures of Correlation, and
(14) Maximal Correlation Coefficient.
Algorithm taken from:
Haralick, R.M., K. Shanmugam, and I. Dinstein. 1973. Textural features for image classification. IEEE Transactions on Systems, Man, and
Cybertinetics, SMC-3(6):610-621.
BUGS
The program can run incredibly slow for large images (larger than 64 x 64) and command line options are limited. The method for finding
(14) the maximal correlation coefficient, which requires finding the second largest eigenvalue of a matrix Q, does not always converge.
