Answer 1

#include <iostream>
#include <cstring>

using std::cout;
using std::endl;

template <class T1, class T2> class Test {
	T1 i;
	T2 j;
public:
	Test(T1 _i, T2 _j)
	{
		i = _i; j = _j;
	}
	void print(void)
	{
		cout << i << " " << j << endl;
	}
};

int main(void)
{
	Test<double, long> o1(3.14, 99999);
	Test<char, char *> o2('z', "C++");

	o1.print();
	o2.print();
