  #include <iostream>

#include <algorithm>
#include <string>
#include <conio.h>
#include "xmedian.h"
using namespace std;

int main()
{
	vector<double> test;
	test.push_back(0);
	test.push_back(1);
	double med=median(test);
	cout<<med<<endl;

	cout << "Press enter to continue...";
    _getch();
	return 0;

}


#ifndef GUARD_xmedian.h
#define GUARD_xmedian.h
//header file to calculate the median of a vector

#include <vector> 
using namespace std; 
double median(vector<double>);


#endif

-------

#include "xmedian.h"
#include <algorithm>
#include <stdexcept>
//#include <vector>
//using namespace std;
//probably we don't need using namespace std?
double median(vector<double> vec)
{
	typedef vector<double>::size_type vec_sz;
	vec_sz size=vec.size();
	if (size==0)
	{
		throw domain_error("median of an empty vector");
	}
	sort(vec.begin(),vec.end());
	if (size%2==0)
		return (vec[size/2-1]+vec[size/2])/2;
	else
		return vec[size/2];

}

the left is the main function

right above is the median header file
right below is the median source file.

Any help would be appreciated!

Figured out my mistake. Should be x_median_h
