Thing to create a 'stack' class that accepts any kind of type for input using vectors instead of arrays per class exercise. For whatever reason doesn't work in VS2012 but compiles online just fine (using the same compiler, go figure). Whatever.

Stack.cpp

#include <iostream>
#include "Stack.h"
using namespace std;

int main () {

  Stack<int> s1;
  Stack<double> s2;

  for (int i = 0; i < 5; i++)
  {
    int value;
    cout << "Enter a value: ";
    cin >> value;
    s1.push(value);
    s2.push(value * 5.5 * i);
  }
 
  while (!s1.empty())
  {
    cout << s1.pop() + s2.pop() << endl;
  }

	system("pause");
	return 0;
}

Stack.h

#ifndef STACK_H
#define STACK_H

#include <vector>

template<typename T>
class Stack {
public:
	Stack();
	void push(T const&);
	T pop();
	bool empty() const;

private:
	std::vector<T> elems;

};

template<typename T>
Stack<T>::Stack() {
	std::vector<T> elems;
}

template<typename T>
void Stack<T>::push(T const& element) {
	elems.push_back(element);
}

template<typename T>
T Stack<T>::pop() {
	elems.pop_back();
	return elems[elems.size()];
}

template<typename T>
bool Stack<T>::empty() const {
	return elems.empty();
}

#endif
