// Het template "numeric_limits" in de C++ standard template library is wat
je nodig hebt.
// Hier is een volledig programma, dat je het gewenste resultaat toont in
een paar microseconden:
//

#include <iostream>
#include <limits>
using namespace std;

template<class A>
class Limits {
public:
  static void show_limits() {
    numeric_limits<A> nl;
    cout << "Size in memory:" << sizeof(A) << endl;
    cout << "Minimum value:" << nl.min() << endl;
    cout << "Maximum value:" << nl.max() << endl;
  }
};

int main(void) {
  Limits<short>::show_limits();
  Limits<float>::show_limits();
  Limits<double>::show_limits();
}
