How do I declare the following constructors in my .h file Below.pdf

The document asks how to declare constructors in a class header file and provides an example class called List. The summary is: 1) The List class constructor and other member functions like insert(), erase(), empty(), size(), get(), and display() need to be declared in the header file. 2) The constructor is declared as List(); without any parameters since it initializes the size and array. 3) Member variables like mySize and myArray also need to be declared in the header file since other functions access them.

How do I declare the following constructors in my .h file?
Below was the original code.
#include const int CAPACITY =1024; using namespace std; typedef int ElementType; // Now
"ElementType" is "int" L//can change int to double, char,... class List { public: List();
//constructor unsigned size() const; bool empty() const; //check if empty void
insert(ElementType item, int pos); //insertion void erase(int pos); //deletion void
display(ostream& out) const; //display every item ElementType get(unsigned pos) const;
private: int mySize; // current # of items in list int myArray[CAPACITY]; No issues found 4

My question is pretty simple, I just want to know how to call my operator== function in Stack.cpp using a list function. Here is what I meant. This is my Stack.h file: class Stack { public: /**constructors and destructors*/ Stack(); Stack(const Stack &S); ~Stack(); void pop(); void push(int data); bool operator==(const Stack &S); [ .......] private: List stack; }; Here is my List.h file: template class List { private: struct Node { listitem data; Node* next; Node* previous; Node(listitem data) : next(NULL), previous(NULL), data(data) { } }; typedef struct Node* NodePtr; NodePtr start; NodePtr end; NodePtr cursor; int length; public: ........ bool operator==(const List &list); [.......] } [........] template bool List::operator==(const List& list) { if (length != list.length) return false; NodePtr temp1 = start; NodePtr temp2 = list.start; while (temp1 != NULL) { if (temp1->data != temp2->data) return false; temp1 = temp1->next; temp2 = temp2->next; } return true; } [......] So I already define my functions in List.h and I only need to call my function from List again in my Stack.cpp file. For example from my Stack.cpp: Stack::Stack(const Stack &S) : stack(S.stack) { } void Stack::pop() { stack.remove_start(); } [......] And I don\'t know how to call my operator== function in Stack.cpp from the List.h like the way above. This is what my guess so far but did not work: bool Stack::operator==(const Stack &S) { stack.operator==(S.stack); } Thank you Solution When we wish to make a comparison, such as in an if statement, we use the double equals sign (==). 1)bool operator==(const Stack &S); [ .......] It means whatever the boolean operator it should be belongs to stack or equal to. 2) bool operator==(const List &list); Likewise link list also compare with the constructor link list. and constructor need not to call explicitly. it will call itself when program called first..

In C++ Write a recursive function to determine whether or not a Linked List is in sorted order (smallest value to largest value). Add the following function prototypes to your List class under the section for access functions, then implement the functions below the class definition: public: /**Access Functions*/ bool isSorted(); //Wrapper function that calls the isSorted helper function to determine whether //a list is sorted in ascending order. //We will consider that a list is trivially sorted if it is empty. //Therefore, no precondition is needed for this function private: bool isSorted(Nodeptr node); //Helper function for the public isSorted() function. //Recursively determines whether a list is sorted in ascending order. #include //for NULL #include #include using namespace std; template //list stores generic list data, not any specific C++ type class List { private: struct Node { listdata data; Node* next; Node* previous; Node(listdata data): data(data), next(NULL), previous(NULL){} }; typedef struct Node* Nodeptr; Nodeptr first; Nodeptr last; Nodeptr iterator; int size; public: /**Constructors and Destructors*/ List(); //Default constructor; initializes and empty list //Postcondition: numeric values equated to zero, or strings should be empty.

Domain Description for the Lunar Rover: Back in July 30th 1971, the crew of Apollo 15 reached the moon surface. The first American astronaut reached the moon along with his team. But they needed a mean of transportation. Their solution: A lunar buggy called Lunar Rover that could travel speeds up to 12 km/h. This was an awesome opportunity for astronauts to travel long distances outside Earth, but there were some technological constraints 45 years ago. The Lunar Roving Vehicle could had only two pedals and two buttons to control the vehicles systems. Moon Roover Movement Control: Engineers had to be creative in order to add all the functionality need for a lunar cruise, so they came up with the following ideas: When the left pedal was pressed once it accelerates the buggy forward. If accelerating forward and you press right pedal once, it deaccelerates. To achieve constant forward speed press the right pedal for more than 3 seconds. If the buggy is at rest and the left pedal is pressed for more than 3 seconds, it will accelerate backwards. Part 1 Design a state machine to model the Movement Control as described above. Note: The description above is not complete. Your task includes filling in these missing details. Make sure to write down any assumptions you make as you develop the state machine model. Part 2- Camera & Drill (Bonus 4 points): The coolest feature of the buggy was not its speed but rather the color television camera, the 16-mm camera, and the drill. The control was packed inside a television control unit. The only problem was that the cameras, and the lunar rover drill were also controlled by the same control unit. So again engineers used the two button controller to manipulate all devices: Press the button 1 for five seconds to interact with the color camera. Press the button 1 for ten seconds to interact with the 16-mm camera. Press button 1 twice to interact with the drill. Pressing button 2 at any of these modes return to idle state. In any of the two camera modes, pressing button 1 takes a picture, while if pressed for 5 seconds activates the temporizer (moon selfies). Last inside the drill mode button 1 only acted as an on off switch. Design a state machine to model the Camera and Drill. Extend the model you developed for the movement control (2 points). Provide an implementation for this extended state machine in Java (2 points). Every state should implement an entry action that prints on the console the current state..

Design a PIC based wearable device that keeps a tract of the activity level of a user. The level of movement should be classed as: immobile, relatively mobile (walking), highly mobile (HIIT). If the user has been immobile for a set amount of time, the device should sound an alarm prompting him to move and only stop when it detects movement. In the mobile state, the device should count the number of steps taken, and store the number and the length of time in that activity state. If the number of steps is more than 10, it should be recorded as an exercise session. The user should be able see a full report of the activities done at the end of the day, including the details of each session in the mobility states. An additional spec can be to record and display the time of day the sessions were done..

Exchange Rate Determination Theory: Overshooting Exchange rate overshooting refers to the process in which the movement of the exchange rate reacts more than the long-term equilibrium state in the short run when a currency volume shock occurs. Answer the following questions. (1) Illustrate and explain the short-term and long-term effects of the increase in the home country's money supply on the local currency volume, the local interest rate, and the exchange rate (the Korean won's exchange rate against the dollar) in a two-country model in which both countries (Korea) and foreign (US) exist. (2) In the problem above (1), picture the movement of nominal currency volume, price level, interest rate, exchange rate, and real currency volume over time (i.e., time path) after the domestic currency volume was moderate..
