Class Template with Multiple Parameters

We can also use more than one generic data type in a class template, they are declared as a comma-separated list.

The general format is:

template <class T₁, class T_{2, .}. . . . . .>

class  class_name

{

          …… … // Body of the class

         

};

/*Program Illustration of class template with multiple parameters*/

template <class T1, class T2>
class Test
{
    T1  a;
    T2  b;
public:
    Test(T1  x, T2  y )
{
    a = x;
    b=y;
}
void  show( )
{
      cout <<a<<”\t”<<b<<endl;
}
}; 
int  main( )
{
    Test <int , float>  test1(1, 2.5);      //one is int and second one is float types
    Test <float , char>  test2(10.5, `A’); //here one is float and second one is char types
    test2.show( );
} 

Output:           1         2.5

                        10.5         A
