Simple Template Class problems

[EmperorCesar]

Below is a very simple Template class. I tested it without the use of templates, and it works fine. I am trying to convert it to a template class.

#include <iostream>
#include <vector>
#include <string>
#include <cmath>

using namespace std;

template <class T>
class Stack
{
private:
int position;
int input;
public:
Stack();
void push(int, int, vector<T> &);
void display(int, vector<T>);
};
template <class T>
Stack<T>::Stack()
{
//nothing

}
template <class T>
void Stack<T>:ush(int position, int input, vector<T> &mainStack)
{
mainStack[position] = input;
return;

}
template <class T>
void Stack<T>::display(int position, vector<T> mainStack)
{
cout <<mainStack[position]<<endl;
}

template <class T>
int main()
{

vector<int> values (25);// declares a vector of 25 integers
values[23] = 8888;
Stack a;
a.push(22, 9999, values);
a.display(22, values);
a.display(23, values);
return 0;
}

I get 2 errors: Can somebody point me in the right direction?

Obviously, main() can't be a template function.

XD wow, I'm an idiot. It works just fine now. Thanks!

EDIT: also, this is what I ended up with.

#include <iostream>
#include <vector>
#include <string>
#include <cmath>

using namespace std;

template <class T>
class Stack
{
private:
int position;
T input;
vector<T> mainStack;
int M;
public:
Stack(int);
void push(int, T);
void display(int);
};
template <class T>
Stack<T>::Stack(int M)
{
mainStack.resize(M);

}
template <class T>
void Stack<T>:ush(int position, T input)
{
mainStack[position] = input;
return;

}
template <class T>
void Stack<T>::display(int position)
{
cout <<mainStack[position]<<endl;
}


int main()
{


Stack<int> a(25);
Stack<char> b(25);
Stack<string> c(25);
a.push(22, 9999);
a.display(22);
b.push(22, 'a');
b.display(22);
c.push(22, "Adam sucks");
c.display(22);




return 0;
}
