c++ - error LNK2019: unresolved external symbol _WinMain@16 referenced in function ___tmainCRTStartup

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

#include
            
#include 
using
            namespace::std;


template             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             Type>
void Stack :: Push (Type &val)
{

            if (top+1
 stack
            [++top]=val;
}

Errors:

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

What
Should I do?
