I need to call one function on my C++ program. I made one root calculator for functions, but, this doesn't work.
// FUNCION QUE CALCULA LA DIFERENCIA ENTRE 2 VECTORES
real mn_error_vectores(Array1D< real > &u, Array1D< real > &v) {
int i;
if(u.dim()!=v.dim()){

no matching function for call to `getline(std::string&, char&)' Why is this error occuring?
My Aim is to copy each character or integer to an array
MY PROGRAM:-
#include <fstream>
#include <iostream>
#include<conio.h>
#include<string.h>
[Code].....
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;

I can remove the "10" from the string first[10] but it doesn't make a difference.What is wrong with this?
I'm having this pain in the ass error (No matching function for call to Data::Data() ) on this block of code:
Etapa::Etapa(string nm, float dist, string loc, Data dt) {
nome = nm;
distancia = dist;
local = loc;
data = dt;
}
[Code].....
I guess this is happening because I'm trying to give Etapa an argument of Data type and I can't do it or put it in a variable since it has 3 parameteres (mes, dia, ano).
This code from [URL] as it is gives compile error I can't understand.

Every time I try to compile this, I get the error message, "error: no matching function for call to" on lines 18, 45, and 46. Basically every time I try to call on the function sales and printStock. I don't know what the message means or why I get it.

My load function isnt working. I've tested it and returned it as an int and it worked but when i tried to compile when i changed it to a template i started getting the errors and I'm not sure how to fix it:

I've written an Array class to create 1d,2d and 3d array and it works fine for every test : example of the constructor of the array class for 2d case:
Array::Array( int xSize, int ySize ) {
xSize_ = xSize;
ySize_ = ySize;
zSize_ = 1;
vec.resize(xSize*ySize);
}
It works fine , but when i need to use this constructor inside of other constructor, i get the "no matching function error" ,

class StaggeredGrid {
public:
StaggeredGrid ( int xSize1, int ySize1, real dx, real dy ) : p_ (2,2) {}

I initialized a nested vector with the following code as:

How do I call a class method which is defined in a .hxx file separately to a .cpp file? Is it any different from how we normally do it (using the scope resolution operator after the class name and then the method name with parameters) ?
View 1 Replies View RelatedI have read the book over and over and I thought I understand "CLASS". But when I applied it and write the code the compiler tells me that there is a compiling error.
1. I have this method addProduct(Product* pProduct) in a Class called ProductRack, the code is in ProductRack.cpp file. The declaration of the Class methods and private variables are in ProductRack.h header file.
2. But when I call a method in the DeliveryCHute Class from the ProductRack Class I get a compiler errors which are these:
A.IntelliSense: a nonstatic member reference must be relative to a specific object
B.error C2352: 'Project1::DeliveryChute::insertProduct' : illegal call of non-static member function
And this is causing the error:
if (Project1::DeliveryChute::insertProduct(pProduct) == false)
//THIS IS JUST ONE METHOD INSIDE ProductRack.cpp
bool
Project1::ProductRack::addProduct(Product* pProduct) {
// Todo : Implementing
if (Project1::DeliveryChute::insertProduct(pProduct) == false)
return true;

View 2 Replies View RelatedI have a problem with the parameters of two of my functions:
typedef List<int> Dlist;
template<class T>
Dlist concat(Dlist L1, Dlist L2) {
Dlist L;
elem<T> *temp1, *temp2;
temp1 = L1.Start_ptr;
temp2 = L1.Start_ptr;
[Code] ....
Here are the errors:
no matches converting function `concat' to type `class Dlist (*)(class List<int>, class List<int>)'
error candidates are: template<class T> Dlist concat(Dlist, Dlist)
no matching function for call to `concat(Dlist&, Dlist&)'
I can't understand what the compiler is trying to tell me.
#include <iostream>
#include <string>
std::ostream& operator<<(std::ostream& os, const std::string& str) {
os << '[';
[Code].....
In the above program, I define an operator<< function in global namespace which has exactly the same signature as the one define in <string> header : [URL] . In the main function, I call operator<< on cout and a string, after which I guess it would cause ambiguity. The result is out of my anticipation, it compiles and prints [hi]. So I guess my function is a better match because it does not require argument-dependent lookup (ADL). Moreover, even if I add using namespace std; at the beginning of the main function, the program still compiles and prints [hi].
In short, I have two question:
#1 : Why is my function a better match (therefore no ambiguity) in the two cases respectively (with and without using namespace std;)?
#2 : Does using namespace affect ADL? Is ADL still performed after applying using namespace, or is it not performed because the function is thrown into global namespace?

I searched the web for error: C3867... and the discussions where murky or obscure.
My code excerpt is:
#pragma once

namespace WordParsor {

I get the generic message:

One person suggested the gcroot<> object wrapper... but I do not know how to modify/declair the function or its argument type.
I've been trying for more than one month to access a method found in a library called libcocosnas_static.a. I'm using Cocos2d-X version 2.0.4. The library has been used many times by my company to make games using cocos2d-1.0.1-x-0.12.0 without any problem.
This is what I've done:
1- I added the include paths of the library to both eclipse and Android.mk
2- Included the .h file using #include "NASPlatformUtil.h"
3- Added the libcocosnas_static.a file to the proj.androidobjlocalarmeabi folder
4- Added "LOCAL_WHOLE_STATIC_LIBRARIES += cocosnas_static" to the Android.mk file
5- Called the function using: NASPlatformUtil:: openUrl("http://xxx.xxx.com/");
I can right click on the function, click Open Declaration and get it without any problem, but the compiler keeps on giving me that dreaded error...
I have been experimenting with variadic templates with the aim of caching a call to a class method by storing away the object pointer, method pointer and parameters. I've actually had some reasonable success but have now hit a stumbling block. I now wish to wrap my parameters in a simple template class when I cache them. My success is as follows:
Using variadic template functions to store these pointers and paremeters;
I'm able to pass a method pointer and unwrapped parametersI'm able to pass wrapped parameters on their own.I'm NOT able to pass a method pointer and wrapped parameters I set up a little prototype project to demonstrate the issue and added comments above the function calls to indicate the compilation results. Here is the code:
Code:
#include "stdafx.h"
//////////////////////////////////////////////////
// Basic class with a simple method
//////////////////////////////////////////////////
class MyClass {
public:
char Method( int i, float f ) {
return 'A';
[code]....
But I'm convinced it should take three arguments, the method pointer and two wrapped parameters. Visual studio even suggested it should as shown below:
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.
