/*Here we use template class
It is used to define our own data type which we want output
if we want float simply add in main function after creating a class  object the
define our required data types
passing a data types
simple data type syntax
template<class T>
class_name <"The data type you want">functon_name or constructor
Multiple data
template<class T1,class T2>
DEfalut parameters
template<class t1=int,t2=float>
class-name<>function_name
---------------------Sir NAUMAN ---------------
placeholder  == (T) <- it usually we will use 't' to define type of functions
template ==It is runtime :
