While I am running the simple code as below I have two errors as following:

```
#include <iostream>
#include <string>
using namespace::std;

template <class Type>
class Stack
{
public:
    Stack (int max):stack(new Type[max]), top(-1), maxsize(max){}
    ~Stack (void) {delete []stack;}
    void Push (Type &val);
    void Pop (void) {if (top>=0) --top;}
    Type& Top (void) {return stack[top];}
    //friend ostream& operator<< (ostream&, Stack&);
private:
    Type *stack;
    int top;
    const int maxSize;
};

template <class Type>
void Stack <Type>:: Push (Type &val)
{
    if (top+1<maxsize)
        stack [++top]=val;
}

```

Errors:

> 
> MSVCRTD.lib(crtexew.obj) : error LNK2019: unresolved external symbol `_WinMain@16` referenced in function `___tmainCRTStartup`

What Should I do?
