note: do not use operator overloadin,and sting data type Create a class HugeInteger that uses a 40-element array of digits to store integers as large as 40 digits each. Provide member functions input, output, add and subtract.For comparing HugeInteger objects, provide functions isEqualTo, isNotEqualTo, isGreaterThan ,isLessThan, isGreaterThan Or EqualTo and isLessThan Or EqualTo—each of these is a “predicate” function that simply returns true if the relationship holds between the two HugeIntegers and returnsfalse if the relationship does not hold.
Subject Object oriented programming DO task in C++ Start with the safearay class from the ARROVER3 program in Chapter 8 of Object Orient programming by Rober Lafore. Make this class into a template, so the safe array can store any kind of data. Include following member functions in Safe array class. The minimum function finds the minimum value in array. The maximum function find the maximum value in array. The average function find average of all the elements of an array. The total function finds the running total of all elements of an array. In main(), create safe arrays of at least two different types int and double and store some data in them. Then display minimum, maximum, average and total of array elements. Note: use subscript ([]) operator in sasfearay class.
(HugeInteger Class) Create a class HugeInteger that uses a 40-element array of digits tostore integers as large as 40 digits each. Provide member functions input, output, add and subtract.For comparing HugeInteger objects, provide functions isEqualTo, isNotEqualTo, isGreaterThan,isLessThan, isGreaterThanOrEqualTo and isLessThanOrEqualTo—each of these is a “predicate”function that simply returns true if the relationship holds between the two HugeIntegers and returns false if the relationship does not hold. Also, provide a predicate function isZero. If you feelambitious, provide member functions multiply, divide and modulus.
Revise the following Course class implementation in the following c++ code When adding a new student to the course, if the array capacity is exceeded, increase the array size by creating a new larger array and copying the contents of the current array to it. Implement the dropStudent function. Add a new function named clear() that removes all students from the course. Implement the destructor and copy constructor to perform a deep copy in the class. Write a test program that creates a course, adds three students, removes one, and displays the students in the course.
Using the scenario of Object oriented programming oop Q A designer in 3D graphics company wants to design a matrix as a two-dimensional array. The size of 2D array could be the last two digit of arid number. Initially he creates a class matrix that provides the member function to check that no array index is out of bounds. Make the member data in the matrix class a 10-by-10 array. A constructor should allow the programmer to specify the actual dimensions of the matrix (provided they’re less than 10 by 10). The member functions that access data in the matrix will now need two index numbers: one for each dimension of the array. Here’s what a fragment of a main() program that operates on such a class might look like: If my Arid Number is 20-Arid-254 then: // in case of zero consider next digit matrix m1(5, 4); // define a matrix object int temp = 12345; // define an int value m1.putel(7, 4, temp); // insert value of temp into matrix at 7,4 temp = m1.getel(7, 4); // obtain value…
in c++: Implement the Array class that is defined below and test it in the main program. The main program must test all the member functions including the overloaded operators that are defined in the class: #ifndef array_h #define array_h #include <iostream> using namespace std; class Array { // Class declaration friend const Array operator+(const Array & a1, const Array &a2); friend bool operator==(const Array & a, const Array &b);//Equality test public: Array(int = 10); //Initialize the array with 0 values, default size =10 Array(const Array & a); // copy constructor ~Array();//Destructor int getSize();// return the size of the array. const Array & operator=(const Array & a);//assignement operator Array operator+(int x);//+ operator bool operator!=(const Array & a) const;//Not equal test void read(); void print(); Array operator-();//Negate (unary operation)…
3. Write a function named “getCombinedPurchaseOrder” that accepts an array of PurchaseOrder object pointers, its size, description, and cost per item. It will go through the list in the array and return a pointer of a new PurchaseOrderobject that contains the total quantity of all the matched PurchaseOrderobjects(with the same description symbol and cost per item). It will return NULL if there is no match. For example, these 2 PurchaseOrderobjects with (100, 1.25, "A box of candy") and (200, 1.25, "A box of candy")will be combined into one new PurchaseOrderobjecthaving the quantity of 300. Please note that this function returns 2 separate values: the pointer to the newly created object and the number of matched PurchaseOrderobjects found in the list. 4. Write a function named “removeNegativePrice” that accepts the vector of pointers to PurchaseOrderobjects. It will go through that list and remove all PurchaseOrderobjectswiththenegativecost per item. It will also return how many…
Language: JAVA Script write a function 'keyValueDuplicates (obj) that takes an object as an argument and returns an array containing all keys that are also values in that object. Examples: obj1 = { orange: "juice", apple: "sauce", sauce: "pan" }; console.log(keyValueDuplicates (obj1)); // ["sauce"] obj2 = { big: "foot", foot: "ball", ball: "boy", boy: "scout"};console.log(keyValueDuplicates(obj2)); // ["foot", "ball", "boy"] obj3 = { pizza: "pie", apple: "pie" pumpkin: "pie"); console.log(keyValueDuplicates (obj3)); // [] *******************************************************************/function keyValueDuplicates (obj) { | // Your code here } /*****DO NOT MODIFY ANYTHING UNDER THIS LINE*********/ try { | module.exports = keyValueDuplicates; } catch (e) { | module.exports = null;}
Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise. A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks
( In c++and oop ) without using vectors or data structure . Create a class IntegerSet for which each object can hold integers in the range 0 through 100. A set is represented internally as an array of ones and zeros. Array element a[ i ] is 1 if integer i is in the set. Array element a[ j ] is 0 if integer j is not in the set. • The default constructor initializes a set to the so-called “empty set,” i.e., a set whose array representation contains all zeros. • Provide member functions for the common set operations. For example, provide a unionOfSets member function that creates a third set that is the settheoretic union of two existing sets (i.e., an element of the third set’s array is set to 1 if that element is 1 in either or both of the existing sets, and an element of the third set’s array is set to 0 if that element is 0 in each of the existingsets). Provide an intersectionOfSets member function which creates a third set which is the set theoretic intersection of two existing sets…
(Polynomial Class) Develop class Polynomial. The internal representation of a Polynomialis an array of terms. Each term contains a coefficient and an exponent, e.g., the term2x4has the coefficient 2 and the exponent 4. Develop a complete class containing proper constructorand destructor functions as well as set and get functions. The class should also provide the followingoverloaded operator capabilities:a) Overload the addition operator (+) to add two Polynomials.b) Overload the subtraction operator (-) to subtract two Polynomials.c) Overload the assignment operator to assign one Polynomial to another.d) Overload the multiplication operator (*) to multiply two Polynomials.e) Overload the addition assignment operator (+=), subtraction assignment operator (-=),and multiplication assignment operator (*=).
