Write a program to declare class data member using template.
#include<iostream>
using namespace std;
template <class T1,class T2>
class A
{
private:
T1 x;
T2 y;
public:
A(T1 a, T2 b):x(a),y(b)
{
cout << "parameterized constructor" << endl;
}
void print()
{
cout << "x = " << x << " y = " << y << endl;
}
~A()
{
cout << "destructor" << endl;
}
};
int main()
{
A <int,int>obj1(10,20);
A <char,char>obj2('a','A');
A <float,float>obj3(54.34,75.32);
A <int,char>obj4(10,'p');
A <char,float>obj5('a',46.23);
A <float,int>obj6(54.34,75.45);
obj1.print();
obj2.print();
obj3.print();
obj4.print();
obj5.print();
obj6.print();
return 0;
}
Output
