casting template using const_cast

[puru]

I have a template class like below.
template <TInt S> class XYZ
{

}

const XYZ<10> abc; //Instance of the class

How do remove the constantness of abc using const_cast. I mean, I want
the syntax for that. Something like const_cast<XYZ<10>> abc gives
compiler error.

const_cast can only do with pointer, reference and pointer to
member(function).

try this

XYZ<10>* p = const_cast<XYZ<10>*>(&abc);

Others have explained how, but I believe having to cast is a design
error. Instead of casting yourself out of your errors, you should
correct the design, which in the long run is going to save you time
and trouble.
