C++ Idk how to refactor the code below to use smartpointers and implement the class as a Template class. Add a function to test your DynamicArray changes. Note: Apply the template type to the declaration int* base as T* base: template <typename T> class DynamicArray { T* base; ... Other 'T' changes will also be needed in the original code. If there are any errors in the code, please fix it to let it become a good program. class DynamicArray{ int* base; int size = 0; int capacity = 0;public: DynamicArray(int c = 10) : capacity(c), size(0) { allocate(capacity); } void set(int v, int offset) { if (offset >= capacity) resize(capacity * 2); base[offset] = v; size++; } int get(int offset) { return base[offset]; } int length() { return size; } int extent() { return capacity; } int begin() { return base[0]; } int end() { return base[size - 1]; } void push(int t) { set(t, size); } void…
Can I please get help writing this in C++ Write a class called Word that stores a word from a product review in a data member called “word.” The class should also contain an integer variable representing the number of times (i.e. frequency) that the word was found in a product review document. The class should have a one-argument constructor that receives a pointer to a c-string (character array) containing the word as its one parameter. (Note that the output of the strtok_s function described above is a pointer to a c-string containing the word that was parsed. This is what you will pass in to the Word constructor.) The Word constructor should also set the frequency of this Word object to 1. Appropriate set and get functions should be included for both the word and frequency data members. Write a class called Review that contains a vector of objects of the Word class. The class should contain functions to add a new Word object to the vector and to print out all of the Words in…
C++ Q2: Write a program that defines a (value) as a base class with a set_values () function that give value to integer (val). Then define sub-class square, that calculate the square of the value squar (). In the main, define object of square (sq) and then call the functions in this object.
of the following statements are correct regarding the use of templates in C++ progra Template parameters can only be basic C++ types. Templates can have default values for type parameters. O Templates can be created for classes or standalone functions. Using templates slows down program execution. The use of templates prevents the use of object-oriented programming.
using c++ .Assuming you have a class Student1- Implement the class constructor and print member function.2- Overload the operator < such that it compares the names of 2 student objects.3- Save the class declaration and implementation in a single header file named as Student.h4- Include your Student.h in the main file.5- Now implement as template functions:• A quadratic sorting algorithm (bubble, selection or insertion) • The sub-quadratic algorithm Shell Sort with Hibbard’s increments (look it up).• Another sub-quadratic algorithm (quick or merge sort)class Student{ string name; string id; double gpa; public: Student(string, string, double); void print();};6- Read into 3 dynamic arrays of student objects (a1, a2 & a3) from a file named students.cpp which will have the number of students followed by their info as follows:7- Sort the 3 arrays , each using one of the 3 sorting algorithms you implemented in step 5. For example a1 will be sorted using selection sort, a2 will be…
What must you be sure of when passing a class object to a function template that uses an operator, such as * or >?
Hello, I am having some trouble with this C++homework question. 1. Implement the following:a. A template class named MyArray.1) MyArray is a dynamic partially filled array for primitive types.2) data members: - a pointer for the array - any associated variables needed to manage the array.3) Constructor must insure that specified capacity is possible. Exit the program ifan illegal value is specified.4) “The Big Three” are required to insure deep copy.5) Private grow function is used to automatically increase the size of the arraywhen adding elements.6) Add function to safely append elements to the array.7) getSize function that returns the current number of elements.8) Overloaded the [] operator to read and update existing elements. Test using following main function (DO NOT CHANGE the provided int main as any changes will not be accepted) int main() { cout << endl; MyArray a(2); for(int i=0; i<20; i++) { a.add(i+1); } a.output(); MyArray c(20); for(int i=0;…
C++ please help me answer this question I will give you a good rating Thank you! 1. Fill in the blanks. Use commas to separate your answers. The _________ pointer is available in every C++ non-static class member function, used to refer to the object that calls the function. Using it in conjunction with the _________ operator lets us access the object's data members. You can use a derived class anywhere you can use a base class. This is because a base class and a derived class share a(n) _______. __________ member functions are dynamically bound to an address based on the object that calls it at runtime. This is unlike regular functions that are statically bound to an address at __________ time. All function-template definitions begin with the keyword __________, followed by a list of template parameters to the function template enclosed in ____________.
PPM (Portable Pixmap) use three integers to represent a pixel – this means we can have images with RGB colors. You will create a Pixel class in C++ which has three attributes: red: int green: int blue: int You will create a default constructor that initializes those values to 255, and an overloaded constructor that takes user input to assign the values. The class will also have the following functions: changeRGB (): Takes in three integers to update the red, green, and blue attributes. Returns nothing. printRGB (): Takes in nothing. Prints the red, green, and blue attributes in order with a single space in-between each value. Returns nothing. You will then recreate the art program from Assignment 5 with the following changes: Instead of a 2D array of integers, you will create a 2D array of Pixel object. Don’t be scared! This is similar to creating a 2D array of strings. You will prompt for three color values instead of one – red, green, and blue. These must be stored in a Pixel…
Research assistants provide support to professionals who are conducting experiments or gathering andanalyzing information and data. Suppose you are working as RA (research assistant) with a Professor who isworking on a project and evaluating complex mathematical equations. Your duty is to assist him, so in thisregard he has assigned a task to you. Your task is to write a oop c++ program to create a class named equation which will have the data members a, b and c which are the coefficients of the quadratic equation. The class will have two more data members namely proot and nroot which stand for the positive root and negative root of the equation. Suppose that variables a, b and c are integers. Where proot and nroot are floats. Input Function to get values of a, b and c Then design a friend function which will determine the proot and nroot of the equation. Create another friend function which will display the values of proot and nroot.

C+++ I need help filling in missing/needed code to to do the following: Read two doubles as the forceApplied and the contactArea of a BallObject object. Declare and assign pointer myBallObject with a new BallObject object using the forceApplied and the contactArea as arguments in that order. Then call myBallObject's IncreaseForceAppliedAndContactArea() member function. Ex: If the input is 3.0 2.5, then the output is: #include <iostream>#include <iomanip>using namespace std; class BallObject { public: BallObject(double forceAppliedValue, double contactAreaValue); void IncreaseForceAppliedAndContactArea(); void Print(); private: double forceApplied; double contactArea;};BallObject::BallObject(double forceAppliedValue, double contactAreaValue) { forceApplied = forceAppliedValue; contactArea = contactAreaValue;}void BallObject::IncreaseForceAppliedAndContactArea() { forceApplied = forceApplied * 5.0; contactArea = contactArea * 5.0;…
