Templates are mainely used for creating the generic classes

Template is used for generic programming. In other words 
when you want to write a function or a class type 
independent, go for templates.

template<class T>
void fun(T x, T y); // Is a Template function

template<typename T>
class abc{
T m;
}; // Is a Class Template

template<class T>
class abc{
T m;
}; // Is a Class Template

templates r used to create generic classes and functions.
