by Factory design pattern in C++ is a creational design pattern which deals with creating objects without showing the exact class of object that is being created. This design pattern basically allows a class to defer the instantiation to sub-classes. General class diagram of Factory pattern is shown below.

Sometimes to create a complex class objects increases the object constructor parameter combination which leads to large number of constructors. Instead of using several constructors, Builder pattern uses another object called “Builder” that receives all the initialization arguments and returns the final object.
