Programming Exercise 11 in Chapter 8 explains how to add large integers using arrays. However, in that exercise, the program could add only integers of, at most, 20 digits. This chapter explains how to work with dynamic integers. Design a class named largeIntegers such that an object of this class can store an integer of any number of digits. Add operations to add, subtract, multiply, and compare integers stored in two objects. Also add constructors to properly initialize objects and functions to set, retrieve, and print the values of objects. Write a program to test your class. I am needed all three guide headers, this is what I have been provided with: main.cpp #include  using namespace std; int main() {     // Write your main here     return 0; }   largeIntegers.cpp #include  using namespace std; largeIntegers.h //Specification file largeIntegers.h   #ifndef H_largeIntegers  #define H_largeIntegers    #include  using namespace std; #endif   I need help with these three different codes in order for the program to run correctly in Cengage. Any help would be appreciated.

Can you please help me with this, its in java. Thank you.   Write classes in an inheritance hierarchy Implement a polymorphic method Create an ArrayList object Use ArrayList methods For this, please design and write a Java program to keep track of various menu items. Your program will store, display and modify salads, sandwiches and frozen yogurts. Present the user with the following menu options: Actions: 1) Add a salad2) Add a sandwich3) Add a frozen yogurt4) Display an item5) Display all items6) Add a topping to an item9) QuitIf the user does not enter one of these options, then display:Sorry, <NUMBER> is not a valid option.Where <NUMBER> is the user's input.   All menu items have the following: Name (String) Price (double) Topping (StringBuilder or StringBuffer of comma separated values) In addition to everything that a menu item has, a main dish (salad or sandwich) also has: Side (String) A salad also has: Dressing (String) A sandwich also has: Bread type…
