C++ :: Request For Member When Call Function

Oct 22, 2013

I'm writing a small c++ program which will be able to do a few things with a matrix. I have a class called Matrix and a member function in it called getSor() which returns an integer value about the number of lines in the matrix. When I call this getSor() function the program says: error: request for member ‘getSor’ in ‘matrix’, which is of non-class type ‘Matrix*’

- 'matrix' is an existing Matrix object here
- I called the function like this: "cout << matrix.getSor() << endl;"

C++ :: Call To Member Function X Is Ambiguous - Overloaded Member From Header File

Feb 23, 2014

I get the following error in XCode whenever I try to access the member I created 'randomGen' in a separate class in a different header file. I have made sure to include the header file and have tried to access it through an object.

This is the code I enter when trying to access the method from randomiser.h in main.cpp. It is also an overloaded function with doubles and integers:

RandomG randomiser;
randomiser.randomGen(); // 'Call to member function 'randomGen' is ambiguous'

This is the code inside randomiser.h:

#include <string>
#include <iostream>
using std::string;
using std::cout;
using std::endl;
class RandomG {

[Code] ....

This is the error inside xcode: [URL] ....

I have tried seperating the code for the functions in another class (main.cpp) and then running and it seems to works, so I'm not sure why I can't put everything in the .h file and then access it?

I would like it in a seperate file so it doesn't clutter my main. I am writing a game with SDL so that might be confusing and I would like the window to have a random title and other random properties, so it would be easier to use a function.

C++ :: Call Member Function Inside Another Member Function?

Mar 21, 2013

For example, if I have Find(int key) defined already and wanted to call it while i was overloading operator+.

C :: Recursive Function Not Displaying Correct Sequence Request

Jul 1, 2013

Ok, so the assignment is to use a recursive function to display a request for a certain position in the Fibonacci Sequence (0, 1, 1, 2, 3, 5, 8, 13...)

The program I have written works, but it displays the wrong number in sequence. The book says that when you enter "8" you should receive "13", which is correct in the order of the sequence, though my program is producing "21" which is the next number in the sequence.

I tested it with a few more numbers and when I enter "7" it produces "13" and when I enter "6" it produces "8" and so on.

Code:
//Cameron Taylor
#include <stdio.h>
int main(){

C/C++ :: How To Call Member Functions With Template Based Class

Sep 27, 2014

This week we are learning to use templates, and I don't understand how to call my member functions with my template based class. I tried the standard convention of calling member functions, but I keep getting an error saying name following"::" must be a class or namespace name. I'm thinking my problem lies with my typename T, but I am unsure. Line 16 is where I am getting tripped up.

#include "stdafx.h"

Visual C++ :: Error C3867 Function Call Missing Argument List For Calling Thread Function

Mar 19, 2013

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.

C++ :: Call Of Non Function

Jan 9, 2015

I have decalred a password function which accepts an array as parameter but while compiling, it's showing an error wherever I have called it.

void password(char a[100])
{
if(::q==1) { cout<<"
Enter the master password : "; goto ENTER; }

[Code]....

Wherever I have called this function it's showing an error: "Call of nonfunction." One of the examples of the errors is below:

::q=1;
password(master_password);
//Both 'q' and 'master_password' being global variables, and master_password being array of size 25.

C# :: Responding To A Request Made From Mobile App

Feb 8, 2015

I want to know how to respond to a request made by a mobile application (preferably Android) through a desktop software. So for example if there is a button on the mobile app named 'do something and a user clicks it, I want the desktop software to respond to that request and 'do something

So what I was thinking was to upload a file to a server when the button on the app is clicked and add a timer to the desktop software to connect to the server and read the file and respond accordingly.

Is this how it is usually done or am I going about this the wrong way? Im developing the app in C# (Xamarin) and the desktop software in C# as well.

C++ :: Server Request Line Validation?

Oct 30, 2014

I have problems relating the HTTP server request line validation into a c++ code, where the request line is defined as follows:

method SP request-target SP HTTP-version CRLF

and the server supports absolute-path [ "?" query ]

At the same time absolute-path must start with / and might optionally be followed by a ? followed by a query, which may not contain ".

Basically, method must be GET, request-line must begin with / , request-target cannot contain " ,HTTP version must be 1.1 (HTTP/1.1), and the absolute-path must contain the character .

C++ :: No Matching Function To Call?

Sep 6, 2013

The random method in here should return a random value inside given array.

The program constantly crashes when I send the array object as full.

It will only allow for you to choose the first 4 objects in the array, if you choose object number 8, for example, the program crashes.

So Im trying to send the pointer to the array instead. But now the compiler claims not to know of any such function.

static string getRandom(string* avalible[]){
cout << "Get random";
cout << "index: " << (*avalible)->length() << endl;
int index = random((*avalible)->length()-1);
cout << "returned" + index;

[Code] .....

I can remove the "10" from the string first[10] but it doesn't make a difference.What is wrong with this?
