1)For operator overloading to work, at least one of the operandsmust be a user defined class object. 2)Assignment Operator:Compiler automatically creates a default assignment operator with every class. The default assignment operator does assign all members of right side to the left side and wo...

An operator's precedence is unaffected by overloading. Notes The standard itself doesn't specify precedence levels. They are derived from the grammar. const_cast, static_cast, dynamic_cast, reinterpret_cast and typeid are not included since they are never ambiguous. ...

it won't be perfect. There's obviously no operator overloading, and overriding (i.e. of "methods" in "derived classes") would have to be done by hand. Obviously, if you need "real" OOP, you'll want to use a language that supports it, such as C++. ...
