LW: Class Constructors Objectives Write a default constructor for a class. Note that this constructor is used to build the object anytime an argument is not provided when it is defined. Write a parameterized constructor that takes arguments that are used to initialize the class’s member variables Labwork Download the code associated with this lab: ColorConstructor.zip Main.cpp Color.h Color.cpp Compile and run the code. The first line of output of the program should display nonsensical integers for the values of...

C++ CODE: The matrix class consists of two files: matrix.h and matrix.cpp. The class has the following definition: matrix -size:int -mat:int** ---------------- +matrix(file:string) +~matrix() +operator +(add:matrix*):matrix & +operator-(sub:matrix*):matrix & +friend operator<<(out:ostream &, t:const matrix&):ostream & +displayRow(r:int):void The class variables are as follows: • size: the number of rows and columns in a square matrix • mat: the integer matrix that contains the numeric matrix itself. The methods have the following behaviour: 2 • matrix(file:string): The default constructor. It receives the...
C++ 1. The copy constructor is used for one the following scenarios: I. Initialize one object from another of the same type. II. Copy an object to pass it as argument to a function. III. Copy an object to return it from a function.

Greetings, everybody I already started working in this program. I just need someone to help me complete this part of the assignment (my program has 4 parts of code: main.cpp; Student.cpp; Student.h; StudentGrades.cpp; StudentGrades.h) Just Modify only the StudentGrades.h and StudentGrades.cpp files to correct all defect you will need to provide implementation for the copy constructor, assignment operator, and destructor for the StudentGrades class. Here are my files: (1) Main.cpp #include <iostream> #include <string> #include "StudentGrades.h" using namespace std; int...
13.21 Lab: Rational class This question has been asked here before, but every answer I have tested did not work, and I don't understand why, so I'm not able to understand how to do it correctly. I need to build the Rational.cpp file that will work with the main.cpp and Rational.h files as they are written. Rational Numbers It may come as a bit of a surprise when the C++ floating-point types (float, double), fail to capture a particular value...
