I have a problem with the inclusion of the vector module. It seems to there is a conflit with others modules. Here is the structure :
In the simulation.h :
#pragma once
#ifndef SIMULATION
#define SIMULATION
#include <ostream>
#include <sstream>
#include <string>
#include <algorithm>
#include <cstdlib>
// #include <vector>
#include "File.h"
...
void afficherResultat(std::vector<Client> sortie);
...
#endif
And the File.h file :
#pragma once
#ifndef FILE
#define FILE
#include <vector>
class File {
...
std::vector<Client> l;
...
};
#endif
And I get 108 errors starting with : C4091 warning and C4430, C2065, C4229 errors... Some people spotlight the order of the inclusions. Any Ideas ?
You are defining a macro for an identifier which is part of the standard library:
#define FILE
(see https://en.cppreference.com/w/cpp/io/c#Types for what FILE is).
Doing so is forbidden and will cause very weird errors.
Instead use names which are as unique as possible as include guards, e.g. INCLUDE_GUARD_FILE_H.
If you have an include guard there is also no need for #pragma once which is a non-standard way of solving the double inclusion problem that the include guard is also supposed to prevent.
Additionally you have not declared Client in File.h. Probably some #include for the header file defining Client is missing.
