17.6 Write a program to define a constructor with multiple template variables.

#include<iostream.h>

#include<conio.h>

template <class T1, class T2>

class data

{public:

data (T1 a, T2 b)

{cout<<“\n a=”<<a <<“ b=”<<b;}

};

int main()

{clrscr();

data <int,float> h(2,2.5);

data <int,char> i(15,‘C’);

data <float,int> j(3.12,50);

return 0;}

OUTPUT

a = 2 b = 2.5
