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()’: first.cpp:14:38: error: no matching function for call to ‘Rectangle::Rectangle(<brace-enclosed initialiser list>)’
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;
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).
#include <iostream> #include <string> #include <fstream> #define N 10 using namespace std; class cust{
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 argument 'T' T *load(const char* x, int &size) {
[Code] ....
I'm trying to use my load function to load integers from a file into and array and then return it back.
#include "bubble_sort.h" #include <iostream> #include <cstdlib> #include <string> using namespace std; int main(){ int n, pick = 1, 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&)’ "
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.
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 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 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.
#include <stdio.h> int patt(const int SIZE, char str[], int i, int c); 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'}; int i, c=0;
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?
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.
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;
[Code] ...
//I haven't made the sort function yet since I am stuck with the print(). Seems //like the compiler is skipping the print() function.
