Caution
•One of the most serious drawbacks of class templates is the danger of generating an instance of the class that is incorrect because of type conflicts.
•Except by writing specialized template classes to take care of such cases, there is no way to protect the client from using the class incorrectly, causing erroneous instances of the class to be generated.
•Be very careful when writing class templates to ensure that all possible combinations will create correct classes.
