I'm working on this project that basically reads information from a file, use that information on an object and then creates a list that contains the objects.
I have a class named Acao
which basically contains a few pieces of information, some strings and some floats. Pretty simple;
What I'm trying to do in order to check if my list is being correctly built is to output a float named cMed using the getcMed()
member from Acao class.
Ok, first of all:
I'm getting three errors while trying to iterate through my list, being with operators =
, !=
and ++
.
All of them being - repectively:
error C2679: binary '=' : no operator found which takes a right-hand operand of type 'std::_List_iterator<std::_List_val<std::_List_simple_types<Acao>>>' (or there is no acceptable conversion)
As much as I don't think that really matters in this case, these are my included libs:
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include <list>
#include <stdlib.h>
#include <sstream>
Now then, my second problem with this piece of code is with the line:
cout << (*it)->getcMed();
Both my list
and the iterator it
are of Acao
type, but my compiler (I'm using VS 2013 for my IDE and compiler) gives me the following error:
error C2039: 'getcMed' : is not a member of 'std::list>'
Here's the chunk of code in question (also note: I'm using namespace std for this):
list<Acao> novaListaAcoes(){
fstream file;
streampos begin;
list<Acao> listaAcoes, it;
Acao A;
string linha, papel, companhia, tipo;
float min, med, max;
file.open("G:\\VS\\ConsoleApplication4\\BDINaux.txt");
file.clear();
file.seekg(0, ios::beg);
listaAcoes.clear();
while (!file.eof()){
getline(file, linha);
if (file.eof()){ break; }
vector<char> vector(linha.begin(), linha.end());
min = calcMin(vector);
max = calcMax(vector);
med = calcMed(vector);
papel = lePapel(vector);
companhia = leComapanhia(vector);
tipo = leTipo(vector);
vector.clear();
A.setCompanhia(companhia);
A.setCotacao(med, min, max);
A.setNomePapel(papel);
cout << papel<< endl;
listaAcoes.push_back(A);
}
cout << "fim loop\n";
for (it = listaAcoes.begin(); it != listaAcoes.end(); ++it){
cout << (*it)->getcMed();
}
return listaAcoes;
}
