CPP program to illustrate template class

In this article we will learnt to implement a CPP program to illustrate template class. A C++ program is provided below to illustrate class template.

Program is as follows:

#include <iostream>
using namespace std;
template<class T>
class Swapper
{
	private:
		T x;
		T y;
	public:
		Swapper(T x, T y)
		{
			this->x = x;
			this->y = y;
		}
		void swap()
		{
			T temp = x;
			x = y;
			y = temp;
		}
		void display()
		{
			cout<<"After swap x = "<<x<<", y = "<<y<<endl;
		}
};
int main()
{
	Swapper<int> s1(2, 4);
	s1.swap();
	s1.display();
	Swapper<double> s2(4.2, 6.9);
	s2.swap();
	s2.display();
	return 0;
}

Output for the above program is as follows:

After swap x = 4, y = 2
After swap x = 6.9, y = 4.2
