Im new to debugging but it says the problem is on line 97 which is the verb menu function being called in the first switch statement case 0:
verb menu is one of the sub menus i want ,and it loads but then it crashes ...
#include <iostream>
#include <string>
#include "spanishverbs.h"
#include <windows.h>
#include <cmath>
#include <cstdlib>
using namespace std;
void nounmenu();
[Code] ....
Any time I run my program after I make a selection from the menu the output is printed on the console screen then immediately a windows screen comes up saying project.exe has stopped working.
Below is my code, and I suspect the error has something to either
A) due with how I'm calling the method or
B) how I have the method coded.
Main
#include <iostream>
#include <fstream>
#include <string>
#include "telephone.h"
#include "tbook.h"

This program I'm working on accepts an array size from the user, prompts the user to store that many integers, sorts them from smallest to largest, and then searches for duplicates with a simple for loop. The ultimate goal of the assignment was to display duplicates in an array, and the rest of the functions are just how I decided to reach that goal.
Anyway, my program crashes if I choose an array size larger than 7. It sorts and displays duplicates perfectly with 7 or fewer arguments.
The exact moment it crashes is after I enter the final value it prompts me for, so it appears my inputsize() function and my inputarray() function are working, and the error may be in the arrsort() function. Code is below:
Code:
#include <stdio.h>
int funcinputsize(int);
void funcinputarray(int [], int size);
void funcarrsort(int [], int size);
void funcdupe(int [], int size);
[Code] ...
The first problem i'm having is in the following code.
Code: #include<stdio.h>
#include<stdlib.h>
#include<time.h>
// program ask for max value and always returns random numbers < max
[Code].....
The ultimate goal of these two programs is to merge them and make one program that takes a max value from the user and fills up an array of (10^6) elements with values ranging from (0 to maxValue).
i have this program I am working on and it seems to crash after the function call getdata()
here is the code
#include<iostream>

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.
The function is supposed to return value from the file in my main, but I am getting empty value. I am trying to get better with pointer. Right now just teaching myself.
right now the only way for this code to show value is when in put the putchar(*ps) inside my readfile function. I would like to readfile to return value and print in the main function.
Code:
#include <stdio.h>
char *readfile(char filename[]);
int main(int argc, char *argv[] ) {
[Code].....
Here is a sample of my question
class Base{
public:
int getNum();
private:
int numToGet;
}
class Derived: public Base {
public:
friend ostream& operator<<(ostream& output, const Derived &B);
[Code]...
Is this possible?
int myfunc( int a, int b, char * c )
char a = "(int)myfunc()";
char b = "(int,int,char*)"
call(a, b, ...) // Function name and return type, params
I want to do function what registers forward what will get callback if the time is right. Basically then i dont need to edit and add extra functions into source files. I just have to include header and use register forward function. If there is anything close to this it would be perfect!
I have this sample code, that calls a function in a DLL. The function Callback is provided to the DLL as an argument, in order for the DLL to notify my program of relevant changes.
sample:
#include <iostream>
#include <conio.h>
#include <windows.h>
#include <winbase.h>
#include "TcAdsDef.h"
#include "TcAdsApi.h"
using namespace std;
void _stdcall Callback(AmsAddr*, AdsNotificationHeader*, unsigned long);
[Code] ....
I would like to change this code, so that there is a Main class that opens the connection and there are several separate classes (as below) that register themselves for a specific variable and get notifications if that value is changed. The reason for this is that I want to get several notifications for several independent events and I don't want them to mix. I figured this should look something like this:
class.h
#ifndef INACLASS_H
#define INACLASS_H
#include "Main.h"
class InAClass {
public:
InAClass(Main* mainClass, std::string iolocation);
[Code] ....
Unfortunately this gives me an error:
error: cannot convert 'InAClass::Callback' from type 'void (InAClass::)(AmsAddr*, AdsNotificationHeader*, long unsigned int)' to type 'PAdsNotificationFuncEx {aka void (__attribute__((__stdcall__)) *)(AmsAddr*, AdsNotificationHeader*, long unsigned int)}'
At first I thought this was because I don't have the namespace "using namespace std;" on top, but then I should be able to find something that specifically needs to come from the std namespace and is not marked as such. I don't want to rule the option out, but so far I could not find anything like that.
An alternative explanation might be that the Callback function needs to be global, but if I make it global, how can I distinguish between several Callback functions?
Every time I try to use the function SaveNewCD, it doesn't write to file correctly. It writes the ~, three characters, then goes into an infinite loop.
#include<iostream>

using namespace std;
int SaveNewCD();
int OpenCD();
int main() {
char ArtistName[25];

I am trying to use ofstream to write in a txt file in a function called recurrently. for a simplified example:
void func_write(double x) {
ofstream myfile;
myfile << "the result = " << x << endl;
} int main() {
ofstream myfile;
[Code] .....
To this stage, it does not work, because the myfile in func_write cannot write in the txt file opened in main function. I don't want to open, append and close the txt file each time the function is called, that will take more time to execute all (imagine with 500 calls).
I want to call the array from one function to another all function not a main function

How would I call a string that sits within a switch loop in the main function, into a separate function?
Like this:
void statistics() {
cout << "Here are the statistics for your entry: " << endl;
cout << "
The size of your entry is " << s.length() << " characters." << endl;
}
I am calling string s from this:
switch (toupper(myChoice)) {
case 'A': cin.ignore();
cout <<"
Please enter your text: ";
getline(cin, s);

I have two functions bool check_key(string cKey, string eKey) and bool check_digit(char digit1, char digit2), and I have declared both of them globally (is this the right terminology?) right after the "using namespace std;" and right before the "int main(){".
In the first one, I called the second one . But it is giving me the error: "no match for call to `(std::string) (int&)' ".
Code:
bool check_key(string cKey, string eKey) {
if(cKey!="" && eKey=="") return false;
if(cKey=="" && eKey=="") return true;
if(cKey=="" && eKey!="") return true;
if(cKey.length()!= eKey.length()) return false;
bool flag=true;

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.
Expected output: 20
But what I got is: 22
Why. While calling sub function it should take the global variable am I right
insert Code:
#include <iostream>
using namespace std;
int a=0;
void sub()

I've been trying to get my program to call void functions with an if statement, but when i run my program and try to call one of the functions "worst case, best case, or random case" it doesn't get called. It just prompts the original menu.

I'm trying to call a function on a derived class that's in a vector of it's base class. I've made the code really simple for illustration purposes:
class Sprite {
virtual void update();
}
class Enemy : public Sprite {
virtual void update();
[Code] ....
I want to be able to just call update() on the items in the vector and the derived class update() functions be called. Currently, it always calls the Sprite update, which makes sense, but it's not what I want. Is there a way to call the derived update function without knowing the type of the derived class?
Is there a way to call a function whose name is defined in a file-stored-list?
In other words: The caller doesn't know in compile time the name of the function.
I'm not talking about polymorphism.
The problem is: I have a list of function names stored in a file, that may change every now and then, and I'd like to call them in the sequence they appear in that list.
I have the code:
void go(CMFCApplication1Dlg * pdlg)
{
pdlg->listcontrol1.InsertItem(0, "Row1");
}
then i call it in thread
Code:
void CMFCApplication1Dlg::OnBnClickedButton3()
{
AfxBeginThread(go(this), NULL, THREAD_PRIORITY_NORMAL, 0, 0, NULL);
}
It doesn't work.
