Question

In C++.

Suppose a restaurant hired you to digitalize all their servers' pads (for taking orders... see picture below). Make a class to represent this pad, which should store multiple of the following: the menu item ordered, special serving instructions (e.g. "no onions"), the quantity requested. Guest Check 234701 SUAVE Than In addition to storing these values properly, make two constructors: a default constructor and a constructor that takes in the menu item (the first item ordered). You do not need to write the definition of these functions, just the declaration. Enter your answer here

Answer 1

Pad class ScreenShot:

class Pad{ // --- Making All fields (instance variables & functions ) public ---- // public: // === All required instance variables Since we have to store multiple orders of a customer. So we will use arrays in which we will store multiple items, their special instructions & quantity of menu items ordered we will dynamically allocate arrays in the constructors string *menuItemsOrdered; // (**) _The menu items which is ordered by customer string *specialInstruction; // (**) It will specify special instructions as mentioned i.e. no onions int *quantity; // (**) _The quantity of that menu item which is ordered // ==== The constructors as specified in statement, just declaration of these functions // (**) A default constructor Pad(); // (**) A parameterizd constructor that takes in the first menu Item ordered Pad(string firstItemordered); 30 };

Program code to copy:

#include <iostream>
using namespace std;

// --- Making a 'Pad' class

class Pad{
  
   // --- Making All fields (instance variables & functions ) public ---- //
  
   public:
      
       // === All required instance variables
      
       /*
           Since we have to store multiple orders of a customer. So we will use arrays in which
           we will store multiple items, their special instructions & quantity of menu items ordered
           we will dynamically allocate arrays in the constructors
       */
      
       string *menuItemsOrdered;       // (**) _The menu items which is ordered by customer
      
       string *specialInstruction;   // (**) _It will specify special instructions as mentioned __ i.e. no onions
      
       int *quantity;               // (**) _The quantity of that menu item which is ordered
      
       // ==== The constructors as specified in statement, just declaration of these functions
      
       // (**) _A default constructor
  
       Pad();
