This is what i think
Instantiation means creating object and instantiation of a template is given by
 class name object
for example
 template
class test
{
};
     so the instantiation of a template is given by
 test t1,t2;

We can force the initialization of template which out creating the object template CMobile;

In the above piece of code, we have initialized the CMobile class of type int without creating the object.

You can force the instantiation of a specialization of the template by specifying a prototype somewhere in your code.  For example:

template <class T> class A {
                T x;
                void f();
        };
        template <class T> void A<T>::f() {}

 template class A<double>;   // this prototype will cause the compiler to instantiate this specialization of the template class

To add...
When a template is specialized as above, it is mandatory to define the same. The C++ compiler will not generate a class for the specialization.
