You cannot swap classes, you can only swap objects. An object is an instance of a class while a class is a type definition; you cannot swap type definitions.
It is not possible to write your own version of the swap algorithm without using templates. You can certainly write a function to cater for a specific type of object, but then you'd need to overload it in order to cater for all possible object types, which is clearly impossible since you have no knowledge of my objects let alone anyone else's.

Distinguish between class template and template class?
Template class: A generic definition or a parametrized class not instantiated until the client provides the needed information. It?s jargon for plain templates. Class template: A class template specifies how individual classes can be constructed much like the way a class specifies how individual objects can be constructed. It?s jargon for plain classes. Class template is a template used to generate template classes. We cannot declare an object of a class template. Template class is an instance of a class template.
Why is a class called a factory of objects?
A factory class is a class that uses the factory method pattern. Factory method pattern is a creational pattern that uses factory methods to deal with the problem of creating objects without having to specify the exact class of the object that will be created. Google for more info.
What do you mean by Instantiating the function template?
Function templates are generic functions for which at least one argument must be a generic type. You cannot instantiate a generic type without knowing its actual type, so until you provide an actual type for the function, the function template cannot be instantiated. You provide an actual type simply by calling the function. If an unambiguous template exists, the compiler generates the actual function for you. At that point the function is said to have been instantiated, just as if you'd written the function by hand. If you call the function again with different types, then new instances of the function are instantiated to match those types, just as if you'd manually written the overloads yourself.
What is simple inheritance?
In object-oriented programming (OOP), inheritance is a way to reuse code of existing objects, or to establish a subtype from an existing object, or both, depending upon programming language support.In classical inheritance where objects are defined by classes, classes can inherit attributes and behavior from pre-existing classes called base classes, superclasses, parent classes or ancestor classes. The resulting classes are known as derived classes, subclasses or child classes.The relationships of classes through inheritance gives rise to a hierarchy. In prototype-based programming, objects can be defined directly from other objects without the need to define any classes, in which case this feature is called differential inheritance.The inheritance concept was invented in 1968 for Simula.
What is meant by a class in java programming language?
A class is a template of a type of object. This common paradigm in object-oriented programming (OOP) allows code that can be reused on slightly different, but common data to reduce code complexity. A template for a vehicle in a video game might store its velocity, fuel, damage, and so on. Most classes have no use until they are "instantiated", at which point the template is applied to an area of memory and it becomes an object. Some classes are never instantiated, as they help other classes, and some classes might have some functions that can be called without an instance (known as static methods). Classes allow for similar or related logic to be grouped together, allows memory to be protected from other code units also loaded in memory, and reduces overall programming complexity.

What is the function of an screw?
The screw is used to hold objects in place, without using anything two dangerous.
Why are classes important in Cpp?
Classes allow programmers to treat data and the operations that work upon that data as self-contained entities known as objects. Objects provide the fundamental principals behind object oriented programming. C++ without classes would simply be another implementation of C, since C++ evolved almost entirely from C.
What is standard template library?
Standard Template Library (STL) is part of the C++ standard library. The <i>template</i> concept in C++ allows to define generic classes which may then be brought to life with concrete types. For example, one could define a template <i>list</i> with repective methods and operators (including an element to a list, finding an element, ...) without specifying the concrete type of the list elements. Later on, one simply defines, e.g., a list of addresses by first defining the class <i>address</i> and then defining a new class as list of this address type.
