For school we have to create a blackjack game using windows form. I had to store the images of each card into a sorted list so i created a class called cardList and created a constructor which contained the the sorted list called cards. So it looks kinda like this:
public class cardList : Form1 { SortedList cards = new SortedList(); public cardList()
[Code]....
There's probably a few other errors, I'm still trying to figure this whole c# thing out. why the error tells me (on the line that contains c.cards.GetByIndex(cardNumber);) that cards is inaccessible due the its protection level.
Code: class X : public Y { public: virtual int query(int, int); // constructor X(int, int);
[Code] .....
And i construct my M and Nby calling :
Code: X Y(a,b); and afterwords by calling
Code: result = Y (c,d) i get my result.
The problem is I need to be able to call result = Y (c,d) from outside my main function and get results but i don't know how to do this. So I want to be able to do something like this.
But then the 2nd part of the question itself says that "Acno entered by the user". So we need to identify/search for an account with that Account Number. How can we do this without comparing Acno with S.Acno? I know that S.Acno is not accesible as it is a private member but then how to compare Acno without even using a member function(public) that can return the value of Acno?
I just happened to find that a nested private template class can be accessed directly outside the enclosing class using a using alias:
namespace ns { class __wrapper { private:
[Code].....
I was hoping to see a "__wrapper::__tklass is private" error message in the first using statement as well as during the instantiation of ns::tklass, but no error is issued. I tried this on gcc-4.9.2, clang-3.5.0 and visual_studio 2013 express.
why exactly doesn't the compiler flag tklass as an error? Is it allowed by the standard? If so, wouldn't that be a serious access violation?
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 have no error compiling, but running my project it stops before entering a function and debugging I have an error about Segmentation fault. The function:
I have no error compiling, but running my project it stops before entering a function and debugging I have an error about Segmentation fault. The function:
Code:
Mat logGabor(matriz filter,Mat filter,double r_o,double theta_o,double sigma_theta, matriz radius,matriz theta,int cols,int rows,double sigma_r,int *padSize){ Mat rpad; int k=*padSize; printf("Welcome to the function"); //Here the error ...
More info: I created the matriz as : typedef double** matriz; and a createmat function that give back a double** and in this function I allocate space for matriz and works. In the main:
Code: Mat chr-Rpad[4][5]; //chrOrient=4;chrScales=5 for(int i_or=1;i_or<chrOrient;i_or++){ for(int i_sc=1;i_sc<chrScales;i_sc++){ //some math calculation chrRpad[i_or-1][i_sc-1]=abs(logGabor(filter,imftt2,r_o,theta_o,sigma_theta,radius,theta,cols,rows,sigma_r,padSize));
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.
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?
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.
This code from [URL] as it is gives compile error I can't understand.
#include <iostream> using namespace std; class Rectangle { int width, height;
[Code] ....
Gives error
(g++ first.cpp) first.cpp: In function ‘int main()’: first.cpp:14:38: error: no matching function for call to ‘Rectangle::Rectangle(<brace-enclosed initialiser list>)’
template <class T> void Arreglo<T> :: Registro (ifstream& Entrada) { Entrada >> Cantidad; Dealer = new T [Cantidad]; for (int i = 0; i < Cantidad; i++) {
[Code] .....
It says the following error when I comile it:
error: expected type-specifier before 'Detail' (*(Dealer + i)).Modelo = new Detail[(*(Dealer + i)).AmountModels]; error: expected ';' before 'Detail'
I am creating code for a group project in my class. All my group members made a header file with an object in it with their functions. One of the functions in my partner's code uses a data member of mine in the function, so she has the function parameter a object of my object. (This isn't the code but for example)
class B { friend class A; void displayAthing(A object) { cout<<object.thing<<endl; }
I have this when I call the function in the cpp file
int main() { A object; B b; b.displayAthing(object); return 0; }
However, when I compile, it gives me an error that the function does not take 1 arguments.
I'm getting an undefined reference error to a function, and I can't figure out why. I have tried letting code blocks compile the files, I have tried the command line to compile it with the same results.
I looked up the error and found this from [URL]
undefined reference Example /tmp/cc2Q0kRa.o: In function `main': /tmp/cc2Q0kRa.o(.text+0x18): undefined reference to `Print(int)' collect2: ld returned 1 exit status
Meaning / Your code called the function Print, but the linker could not find the code for it in any .o file
Usual Causes
You forgot to link the .o file that contains the function
You misspelled the name of the function
You spelled the name of the function correctly, but the parameter list is different in someway
which seems to be the error I get. I have double checked all 4 and I see nothing.
The code that specifically gives me the error is:
Item *name = new Item(desc, id, weight, loc); itemMap.addItem(name);
and the class looks like this:
class Item // Standard Items { private: std::string name; std::string desc; int id; int weight; int loc;
[code].....
I think everything matches up unless I'm just missing it.
I'm working on a short program to calculate the mode of a vector of ints. I am new, so not extremely familiar with pointers, and passing items to functions. This is something I've struggled with (obviously, or I wouldn't be here). I am currently getting the following error when I try to compile this program using g++:
warning: pointer to a function used in arithmetic
I receive this error for the following lines: 66, 73, 75, 81.
I am not using pointers here so I do not understand why this error crops up, much less how to fix it. Here is the code I am struggling with:
#include<iostream.h> #include<conio.h> int main() { setcolor(BLUE); setbkcolor(yellow); cout<<"the text in blue colour with yelow background"; getch(); return 0; }
it keeps returning the same error always in my turbo c++ compiler . What is the correct program for changing background colour and text colour ...
