I'm trying to create a function that calculates the average of all the numbers in my array. But when I run the code the vector in my header says its undeclared. What should I change ?
I have tried putting #include in my header file and using namespace std; but it still doesn't fix my problem. I have also tried passing my function as reference.
Source.cpp
#include <iostream>
#include <string>
#include "math.h"
#include <vector>
using namespace std;
int main()
{
vector<int> notes;
notes.push_back(8);
notes.push_back(4);
notes.push_back(3);
notes.push_back(2);
cout << average(notes) << '\n';
}
math.cpp
#include "math.h"
#include <vector>
using namespace std;
int average(vector<int> tableau)
{
int moyenne(0);
for (int i(0); i < tableau.size(); i++)
{
moyenne += tableau[i];
}
return moyenne / tableau.size();
}
math.h
#ifndef MATH_H_INCLUDED
#define MATH_H_INCLUDED
int average(vector<int> tableau);
#endif MATH_H_INCLUDED

#include <vector>
.std::vector
instead of just vector
.const&
. #ifndef MATH_H_INCLUDED
#define MATH_H_INCLUDED
#include <vector>
int average(std::vector<int> const& tableau);
#endif MATH_H_INCLUDED
