THis is my small program i am getting error CPP 46: 'result::putdata()'is not accessible
#include<iostream.h>

this is my header file
#ifndef Header_H

class CurrentAccount{
[Code] ....
The problem i m facing now is the CurrentAccount class display is showing error inherited member is not allowed....
I am trying to transfer information from form1 to form2 but it will not allow me to do so; I get an error when I write in the coding of
Form2 frm2 = new Form2();
frm2.FN.text = this.FirstName;
The error reads as "Form2 is inaccessible due to protection levels
I have looked over everything and I am pretty sure everything is set to public on both forms how do I fix this?
OgreWidget.h
Code:

The inherited method called createScene is not called.
This code works just fine: [URL] ....

I have a class A, from which three classes Aa Ab and Ac are inherited. In class A I have defined some functions by virtual foo()=0, which I implemented in each subclass. Each class is written in a separated .h and .cpp file.
However, now I think it is possible to overload the operator+ INSIDE each class (including pure virtual in class A), such that something like
int main() {
A *value = new Aa();
A value2 = *value + 1.0f;
}
This should be realizable, because the operator+ is part of the Aa class. Now, I would like to do something like
int main() {
A *value = new Aa();
A value2 = 1.0f + *value;
}
This time, I expect I cannot overwrite the operator+, because it is not part of either class A or class Aa.
Is it possible to do something like this:
class A //parent {
public:
virtual void DoSomething() = 0;
};
class B : public A //child {
public:
void DoSomething(string s) override;
}
Where the child member function overrides and changes the parents member function.
I need to pass an array of key states to the Controller class' Update() function but don't want to send it to every class derived from Object (like Controller).
Is this possible or do I have to overload the original Update() member function (but I would need to define the method in Object then (i.e remove the pure virtual function (=0)))
So i am having troubles with operator overloading in inherited class. Basically, it doesnt work. Consider this:
Code:
class A {
public:
A() {
x=0;
z= new int;
[Code] ....
Some how the copy constructor of a is improperly executed - the pointer is copied over, not re-created. As a result, the destructors crashes due to double-free.
*/
B bb = b; //doesnt work
B bbb(b); //doesnt work
B bbbb(b, 0); //works
}
Above code shows the problem well. The "official" copy-constructor wont work - it copies over the pointer directly, and doesnt create a new one as it should. However, if i provide my own pseudo-copy-constructor that works. But ofcourse it's just a cheap work around - and wont actually work in real code (STL).
compiler is VS2008SP1.
I am trying to pass an object to an inherited clas by a constructor. I am having Cboard my board and i need to pass it to the object Cpawn.
Here under is my code:
main
Code:
#include<iostream>#include "Cboard.h"
#include "Cpawn.h"
#include "Cpiece.h"
void main(){
char location[50];

I have the following problem on my C++ Program and I am not sure why it is not working. I am creating a infix to postfix program through an inherited class which I am not sure it is working.
#include <iostream>

int in_stack_Priority(char a){
if(a == '*' || a == '/')

how to create a base class that is derived (inherited) by three other classes?
View 12 Replies View RelatedI have `MainShop`(base class) then `SwordShop` and `BowShop`(derived classes) and another derived class called `Inventory`. I have a vector under protected in my base class, and when I access it from my derived classes it's okay, but each one has its own value. How can I set them all to have the same value?
//MainShop.h
#pragma once
class MainShop {
private:
//some variables
protected:
vector <string> WeaponInventory;
[code]......
Here every time I run it, it goes straight to the `else` and it displays that I do not have any items. I want to just have one vector for both my bow and Sword shops because vectors take up a lot of memory and my teacher said keep them to a minimum. So I just want one vector that takes in items from my bow class as well as my sword class, but for some reason it's acting as if I have multiple vectors, each with its own set of items.
I need to create a GlobalConfig class. But I want to derive from it in another class.
Here's an example:
public class BaseConfig {
public string GlobalPath {get; set;}
}
public class ConfigA : BaseConfig {
public string pathA {get; set;}
}
public class ConfigB : ConfigA {
public string pathB {get; set;}
}
The idea behind is that I don't want to write the code multiple times and what's more important in class ConfigA I want to set GlobalPath and have access to it in ConfigB.
In other word I want class ConfigB to have a property GlobalPath which was set in class ConfigA.
To clarify I want to have only one object of Config in memory.
When I set BaseConf.GlobalPath to 'A', I want to access it from ConfigB.GlobalPath and also get 'A'.
I always design GlobalConfig as a static class, but static classes can't be inherited. So I tried to implement Singleton Pattern, but ConfigA can't find constructor of class BaseConfig because it's private.
error says "cannot convert 'int*' to 'int' in function main()

I searched the web for error: C3867... and the discussions where murky or obscure.
My code excerpt is:
#pragma once
#include <windows.h>
#include <stdlib.h>
#include <process.h>
void PutUpfrmIO(void *);
namespace WordParsor {
[Code] .....
I get the generic message:
error C3867: 'WordParsor::Form1::PutUpfrmIO': function call missing argument list; use '&WordParsor::Form1::PutUpfrmIO' to create a pointer to memberc:userskingc++wordparsorwordparsorForm1.h... and the suggestion fix generate another error.
One person suggested the gcroot<> object wrapper... but I do not know how to modify/declair the function or its argument type.

I'm new to C/C++. I'm trying to make a program that's going to use the CBLAS libraries that I downloaded on BLAS. After fighting tooth and nail with VC 2005 (I downgraded on purpose because at one point I was desperate.) with regards to solving compilation errors and such and eventually it all compiled just fine.
The problem now is, I get the above mentioned error. It says: "Unhandled exception at 0x0040271c in Try.exe: 0xC0000005: Access violation reading location 0x4e18feb8."
Now there are a few .cpp files (I'm compiling as C code.) which contain the functions and there is one other one which contains my main method. Using the debugger, it goes through 3 files all in all.
The main file: Code: /* cblas_example2.c */
#include <stdio.h>
#include <stdlib.h>
#include "cblas.h"
#include "cblas_f77.h"
[Code] .....
I get the above-mentioned exception in the last line, or:
Code: cblas_dgemm( UNDEFINED, transa, transb, *m, *n, *k, *alpha, a, *lda, b, *ldb, *beta, c, *ldc );
The debugger tells me what the address in the exception is the address if *ldc.
I have en error translating a function from Matlab to C/C++ :
Code:
radius(floor(rows/2+1),floor(cols/2+1)) = 1;
% Get rid of the 0 radius value at the 0
% frequency point (now at top-left corner)
% so that taking the log of the radius will
% not cause trouble.
What I did is:
Code: radius[rows/2][cols/2]=1;
I m sure it s there the problem, because before this line I can print what I want and I can see it at run-time, but after this line I can not print nothing and the work is like blocked. Do you know the error?
I'm working through the Let us C book. One exercise asks me to collect int and float , then pass them to a function that gets product of these and returns it to main. My code looks like this:
Code:
#include <stdio.h>#include <stdlib.h>
main()
{
int a;
float b, c;
[Code]...
So while compiling i get an error about conflicting types for product. I tried to google that error but couldn't understand what's the problem. My only clue is that i can't pass int and float to a function at the same time... Could that be it?
I'm using a library in my code in a file called "my_signal.c". In this file I've defined this function:
Code:
Sigfunc * signal(int signo, Sigfunc *func){
struct sigaction act, oact;
...
}
Since the signal function is also in file signal.h and I included it in "my_sygnal.h" file, I'm wondering why the compiler did not say anything about this "double declaration" of the function with the same name.
double expression(int n, double x) {
double num=(pow((x),2*a));
double den=fact(n,a);
double sum=0;
for(int a=0; a>=0; a++)
sum=pow(x,n)*(num/den);
return sum;
}
I don't know why this isn't working. fact is a factorial function which I have tested and it works fine. But when I input, for example:
int main() {
cout<<expression(1,3)<<endl;
getch();
return 0;
}
it comes up with an error.
I am currently working on a code, but I keep getting a error as follows:
[Linker error] undefined reference to 'getHoursOfTheWeek(double)'

[Linker error] undefined reference to 'getStateTax(double)'
[Linker error] undefined reference to 'getFederalTax(double)'
[Linker error] undefined reference to 'getFICA(double)'
[Linker error] undefined reference to 'getWithHoldingAmount(double)'
I have been trying to debug this error for hours and I am completely stumped....
