USING C++ Implement the Rectangle class below: *******RECTANGLE CLASS******* class Rectangle { private: double width; double length; public: void setWidth(double); void setLength(double); double getWidth() const; double getLength() const; double getArea() const; }; *******END OF RECTANGLE CLASS*******   Enhance the Rectangle class with two new member functions: double getPerimeter() - returns the perimeter of the rectangle, i.e. 2*width+2*length bool isSquare() - returns true if the rectangle is a square, i.e. length is equal to width, returns false if not Demonstrate your class works with the main function that instantiates a Rectangle object and shows sample output for these functions working

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…

1. Implement a class IntArr using dynamic memory. a. data members: capacity: maximum number of elements in the array size: current number of elements in the array array: a pointer to a dynamic array of integers b. constructors: default constructor: capacity and size are 0, array pointer is nullptr user constructor: create a dynamic array of the specified size c. overloaded operators: subscript operator: return an element or exits if illegal index d. "the big three": copy constructor: construct an IntArr object using deep copy assignment overload operator: deep copy from one object to another destructor: destroys an object without creating a memory leak e. grow function: "grow" the array to twice its capacity f. push_back function: add a new integer to the end of the array g. pop_back function: remove the last element in the array h. getSize function: return the current size of the array (not capacity) i. Use the provided main function (next page) and output example Notes a. grow…

using System; class Program { publicstaticvoid Main(string[] args) { int number = 1; while (number <= 88) { Console.WriteLine(number); number = number + 2; } int[] randNo = newint[88]; Random r = new Random(); int i=0; while (number <= 88) { randNo[i] = number; number+=1; i+=1; } for (i = 0; i < 3; i++) { Console.WriteLine("Random Numbers between 1 and 88 are " + randNo[r.Next(1, 88)]); } } }     this code counts from 1-88 in odds and then selects three different random numbers. it keeps choosing 0 as a random number everytime. how can that be fixed?

class temporary { public: void set(string, double, double); void print(); double manipulate(); void get(string&, double&, double&); void setDescription(string); void setFirst(double); void setSecond(double); string getDescription() const; double getFirst()const; double getSecond()const;  temporary(string = "", double = 0.0, double = 0.0);  private: string description; double first; double second; };  I need help writing the definition of the member function set so the instance varialbes are set according to the parameters. I also need help in writing the definition of the member function manipulation that returns a decimal with: the value of the description as "rectangle", returns first * second; if the value of description is "circle", it returns the area of the circle with radius first; if the value of the description is "cylinder", it returns the volume of the cylinder with radius first and height second; otherwise, it returns with the value -1.

Given the previous Car class, the following members have been added for you: Private: string * parts; //string array of part names int num_parts; //number of parts Public: void setParts(int numpart, string newparts[]) //set the numparts and parts int getNumParts() string * getParts() string getPart(int index) //return the string in parts at index num Please implement the following for the Car class: Add the copy constructor. (deep copy!) Add the copy assignment operator. (deep copy!) Add the destructor
