Question
Chapter 8.4, Problem 28STQ
Program Plan Intro
Overriding method:
- • If the subclass inherits a method from its superclass, the overriding method is possible. The overriding method is used to define a methods or behavior that’s specific to the superclass type.
- • Based on the requirement, subclass can be implemented a superclass method.
- • Generally, the overriding method overrides the functionality of a current method.
- • The private method can’t override, because this method can’t accessible outside the class.

Therefore, the class linkedListType and its derived classes unorderedLinkedList and orderedLinkedList can no longer directly access the instance variables of the class nodeType. Rewrite the definitions of these classes so that these classes use the member functions of the class nodeType to access the info and link fields of a node. Also write programs to test various operations of the classes unorderedLinkedList and orderedLinkedList. template <class Type>class nodeType{public:const nodeType<Type>& operator=(const nodeType<Type>&);//Overload the assignment operator.void setInfo(const Type& elem);//Function to set the info of the node.//Postcondition: info = elem;Type getInfo() const;//Function to return the info of the node.//Postcondition: The value of info is returned.void setLink(nodeType<Type>…arrow_forwardQuestion No.1: You are supposed to implement lexer (lexical Analysis).

- In C++, How can I use and apply using templates in my programming assignments? Such as how and when to using templates? Because, I know how to implement them, and theoratically to why we use them, but I am not sure how can I use this in code that involves in polymorphism, such as for example lets say we have a class called player and another class called Roles, and lets say that class Roles is to inherit from Player. How would I use templates in this case? Or even in some cases what is the mindset or logical thinking should I have when developing code involving templates?arrow_forward3.

Develop a high-quality, object-oriented C++ program that performs a simulation using a heap implementation of a priority queue. A simulation creates a model of a real-world situation, allowing us to introduce a variety of conditions and observe their effects. For instance, a flight simulator challenges a pilot to respond to varying conditions and measures how well the pilot responds. Simulation is frequently used to measure current business practices, such as the number of checkout lines in a grocery store or the number of tellers in a bank, so that management can determine the fewest number of employees required to meet customer needs.
