Class Templates
•With class templates, we simply write one class and shift the burden of creating multiple instances of that class to the compiler.
•The compiler automatically generates as many instances of that class as is required to meet the client's demands without unnecessary duplication.
•Specialized (and partially specialized) template classes can be used to handle special cases that arise.
•The syntax for implementing class templates is similar to that of defining and declaring classes themselves. We simply preface the class definition or declaration with the keyword template followed by a parameterized list of type dependencies.
