Question

How to use generic data types in a class with C++

Answer 1

#include <iostream>

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

template <class Type1, class Type2> 
class Class {
	Type1 a;
	Type2 b;
public:
	Class(Type1 _a, Type2 _b) {
		a = _a;
		b = _b;
	}
	void print() {
		cout << a << ' ' << b << endl;
	}
};

int main()
{
	Class<int, double> o1(123, 3.14);
	Class<long, float> o2(93938L, 2.45f);
	Class<char, char *> o3('a', "c++ programming");

	o1.print(); 
	o2.print();
	o3.print();

	return 0;
}
