}#endif // TEMPLATH_DEMO_HXX

TemplateDemo.cpp

#include <iostream>
#include<string>
#include<cstdlib>
#include "TemplateDemo.h"
using namespace std;int main(){Stack<int,20> S20;Stack<int,40> S40;Stack<string,40> Str40;S20.push(7);cout << S20.top() << endl;Str40.push("Hello");cout << Str40.top() << endl;
}
