Given main(), create the Calculator struct that emulates basic functions of a calculator: add, subtract, multiple, divide, and clear. The struct has one data member called value for the calculator's current value. Implement the Calculator struct and related function declarations in Calculator.h, and implement the related function definitions in Calculator.c as listed below: • Calculator InitCalculator() - initialize the data member to 0.0 • Calculator Add(double val, Calculator c) - add the parameter to the data member • Calculator Subtract(double val, Calculator c) - subtract the parameter from the data member Calculator Multiply(double val, Calculator c) - multiply the data member by the parameter Calculator Divide(double val, Calculator c) - divide the data member by the parameter Calculator Clear(Calculator c) - set the data member to 0.0 • double GetValue(Calculator c) - return the data member Given two double input values num1 and num2, the program outputs the following values: 1. The initial value of the data member, value 2. The value after adding num1 3. The value after multiplying by 3 4. The value after subtracting num2 ●くろまる ●くろまる ●くろまる 5. The value after dividing by 2 6. The value after calling the clear() method Ex: If the input is: 10.0 5.0 the output is: 0.0 10.0 30.0 25.0 12.5 0.0 1 #include 2 #include 3 4 #include "Calculator.h" 5 6 // TODO: Define functions 7 // 8 9 /* Type your code here. */ 1 #ifndef CALCULATOR_H_ 2 #define CALCULATOR_H_ Current file: Calculator.c InitCalculator (), Add(), Subtract(), Multiply(), Divide (), Clear(), GetValue() 10 #endif 11 Current file: Calculator.h // TODO: Define the Calculator_struct 5 6 // TODO: Declare functions 7 // 8 9 InitCalculator (), Add(), Subtract(), Multiply(), Divide (), Clear(), GetValue()

7. Employee Management System This exercise assumes you have created the Employee class for Programming Exercise 4. Create a program that stores Employee objects in a dictionary. Use the employee ID num- ber as the key. The program should present a menu that lets the user perform the following actions: • Look up an employee in the dictionary • Add a new employee to the dictionary Change an existing employee's name, department, and job title in the dictionary • Delete an employee from the dictionary • Quit the program When the program ends, it should pickle the dictionary and save it to a file. Each time the program starts, it should try to load the pickled dictionary from the file. If the file does not exist, the program should start with an empty dictionary.

What happens when an object such as an array is no longer referenced by a variable?

int class Inventory { std::vector<Item*> m_Items; static unsigned int m_ItemsMade; void CreateItem() { std::string name = "Item " + std::to_string(m_ItemsMade); m_Items.push_back(new Item(name.c_str(), 100 * m_ItemsMade)); ++m_ItemsMade; } public: Inventory() { CreateItem(); CreateItem(); CreateItem(); } void Print() const { size_t* nSize = new size_t(m_Items.size()); std::cout << "_____INVENTORY_____\n"; for (unsigned int i = 0; i < *nSize; ++i) { m_Items[i]->Print(); } } }; GetValidatedInt(const char* strMessage, int nMinimumRange = 0, int nMaximumRange = 0); This function should first display the provided message to the screen then use cin to get an int from the user. Error check and validate to ensure a legal integer was entered. If not, clear the cin buffer using clear() and ignore() and try again (Note: the buffer still needs to be cleared even if this step was successful). If a legal integer was entered, check its value to see if it is within the...

products := [5] string {"bread", "milk", "eggs", "butter", "sugar"} price := [5] float64{1.29, 3.75, 3.33, 2.97, 5.28} use a "counting loop" to print the products with their prices example: bread: 1ドル.29 milk: 3ドル.75 eggs: 3ドル.33 butter: 2ドル.97 sugar: 5ドル.28

17. Phone Book ArrayList Write a class named PhoneBookEntry that has fields for a person's name and phone number. The class should have a constructor and appropriate accessor and mutator methods. Then write a program that creates at least five PhoneBookEntry objects and stores them in an ArrayList. Use a loop to display the contents of each object in the ArrayList.

And if this is the case it should change the values. This should be done by...

can i get answer plz

Language: C++ Also, create two hurricane objects in the main function and print the average wind speed of them. All the data members can be public.

Fleet class: Instance Variables An array that stores Aircraft that represents Delta Airlines entire fleet A variable that represents the count for the number of aircraft in the fleet Methods: o Constructor-One constructor that instantiates the array and sets the count to aero readFile()-This method accepts a string that represents the name of the file to be read. It will then read the file. Once the data is read, it should create an aircraft and then pass the vehicle to the addAircraft method. It should not allow any duplication of records. Be sure to handle all exceptions. o writeFile()-This method accepts a string that represents the name of the file to be written to and then writes the contents of the array to a file. This method should call a sort method to sort the amay before writing to it. sortArray()-This method returns a sorted array. The array is sorted by registration number.u addAircraft- This method accepts an aircraft and adds it to the fleet(the array only if it is not...

Lab9C: 2D or not 2D For this exercise you will also be writing a program that will be building upon Lab9A. So please make new class file, copy, and rename the code you have already written for Lab9A. Please also rememb to rename the file and (and in the case of Java and C# students) class name to Lab9C. For this exercise, please take the array that was filled up with values and flatten it i.e., convert the 2-0 array to a 1-D array that contains the same values. Please do not just print the 2-D array to look li a 1-D array Hint: You will have to take the 2-D array's total amount of cells and make a 1-D array of the same siz Please refer to the sample output below for visualization and match its style. As always: Remember, the class name should be Lab9C. The user input is indicated in bold. Sample Output #1: Please enter the number of rows: 4 Please enter the number of columns: 4 I have 4 rows and 4 columns. I need to fill-up 16 spaces. The 4x4 array: 1|2|3|4| 5|6|7|8| 9|10|11|12|...

10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array. Demonstrate the class in a program that asks the user to enter five numbers. The program should display the number of digits that match the randomly generated...
