Hi, I'm trying to write a console program that will sort and find the median of numbers that are given in a text file. The text file can have ints or doubles.

The problem I'm having is outputting the median and the insertionSort functions. I think that they are failing because I did something wrong with either the vector or templates or both as it is my first time writing code using both of those.

Any insight is greatly appreciated.

```
#include <iostream>
#include <vector>
#include <fstream>
using namespace std;
template <typename T>
void median(const vector<T> & values) ;
template <typename T>
void insertionSort(ifstream& in_file, vector<T>& a_values);
template <typename T>
void fill_vector(ifstream& in_file, vector<T> & values)
{
T a_value;
while (!in_file.eof())
{
in_file >> a_value;
values.push_back(a_value);
}
}
int main()
{
vector<double> values;
char filename[16];
cout << "Enter a file name: ";
cin >> filename;
cout << endl;
ifstream fin(filename);
if (!fin)
{
cerr << "Could not open the file" << endl;
return 1;
}
fill_vector(fin,values);
cout << "Values entered: ";
vector<double>::iterator p;
for (p = values.begin(); p != values.end(); p++)
{
cout << *p << ",";
}
cout << endl;
cout << "Sorted values are: " << insertionSort << endl;
cout << "Median = " << median << endl;
} //end main
template <typename T>
void insertionSort(vector<T>& values)
{
int i, j, n = values.size(); //i is the pseudo-Code Index and j is the scanIndex
T temp;
// Select List[Index] as element to be inserted into sorted sublist.
// place v[i] into the sublistv[0] ... v[i-1], 1 <= i < n,
// so it is in the correct position
for (i = 1; i < n; i++)
{
// index j scans down list from v[i] looking for correct position to locate temp assigns it to v[j]
j = i;
temp= values[ i];
// find where to insert in the sorted sublistand shift elements to right while scanning
//from right-to-left
while ( j > 0 && target < values[ j-1 ])
{
// shift elements up list to make room for insertion
values[ j ] = values[ j-1];
j--;
}
// the location is found; insert temp
values[j] = temp;
}
}
template <typename T>
void median(const vector<T> & values)
{
double product = 0;
if( values.size % 2 )
{
product = values[values.size() / 2]
}
else
{
product = ( values[values.size() / 2- 1] + [values.size / 2] ) / 2;
}
cout << product << endl;
return 0;
}
```
