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].....
This is the error I keep getting, but I'm not sure how to resolve it.
assignment7.cpp:11: error: no matching function for call to 'Time::display() '
Time.h:18: note: candidates are: void Time::display(int, int)
Code:
#include "Time.h"
int main() {
Time tm;
tm.set(12,53);
dt.display(); //Should display 7/4/1776

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 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()){
printf("mn_error_vectores() : arrays of different dimensions

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.
#include <iostream>
using namespace std;
class Rectangle {
int width, height;
[Code] ....
Gives error
(g++ first.cpp)
first.cpp: In function ‘int main()’:

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.
#include <iostream>
#include <fstream>
#define N 10
using namespace std;
void printStock (float [], int);
float sales (float [], int);
[Code] .....
For whatever reason, I get an error meassage about lines 53-57 saying there is no matching function to call to. Yet the header and the prototype are correct (I think anyways).

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:
all_sort.cpp:41:15: error: no matching function for call to 'load'
int *value = load("./integers.txt", size);
^~~~
./bubble_sort.h:44:4: note: candidate template ignored: couldn't infer template

I'm trying to use my load function to load integers from a file into and array and then return it back.

#include <cstdlib>
#include <string>
using namespace std;
int main(){
int n, pick = 1, size = 0;

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" ,
part of my code:
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:
Code:
vector<vector<Point> > vectorB(4, vector<Point> (int(vectorA.size()), 0));
And came across the following error during link stage:
"/usr/include/c++/4.6/bits/stl_vector.h:1080:4: error: no matching function for call to ‘std::vector<cv::Point_<int> >::_M_fill_initialize(std::vector<cv::Point_<int> >::size_type, int&)’ "
What is Function call Overhead and Function Call Stack?
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?
error says "cannot convert 'int*' to 'int' in function main()
and also
type mismatch in parameter in function sort(int,int)

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 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.
I wrote a program which detects a pattern in an array then returns a valve (x) for each time it does. now i tried to call function patt in main so that i can print x but it doesn't let me do it.

int main(void) {
const int SIZE=21;
char str[SIZE]={'1', '0', '1', '1', '0', '0', '1', '0', '1', '0', '1', '0', '0', '0', '1', '0', '1', '1', '0', '1'};

I want to write a function and be able to call it during execution (say during a while(1) loop). Is this possible without having to parse an input string to extract the function and parameters I need or is that the only way?
View 1 Replies View Related i think my function call is not working and i dont know how to fix it. Basically i want it to output my getstudent function and once i get the information i want it to output with the displaystudent.

void displayStudent(Student x) {
cout << x.first << ' ' << x.last << endl;
cout << x.id << endl;

what is the meaning of identifier before function call in this example? i mean that in syntax context
// Create a stack-allocated handle scope.
HandleScope handle_scope(isolate);
When I call the member function in the main function, two functions are working fine but the third one(print()) is not. The program stops after executing the read_ages function and nothing printed on the screen. This is really strange and I could not find any problem after spending hours and had to post it here.It is a very simple program but I cant find the bug. It is a multiple file program and I am using MinGW as a compiler.
//File 1
#include<vector>
#include<string>
class Name_pairs {
private:
std::vector<std::string>names;
std::vector<double> ages;

//I haven't made the sort function yet since I am stuck with the print(). Seems //like the compiler is skipping the print() function.
I've got These 3 files:
// OTI.h
extern void Unpack(void* Packet);
// PackUnpack.cpp
#include "OptiTrackInterface.h"
void Unpack(void* Packet) {
...
}
// OTI.cpp
#include "OptiTrackInterface.h"
Unpack((char*) &indata);
When i try to compile OTI.cpp, I got the error that Unpack is undeclared.
