defined the cat class in full
Suppose that class Y is a friend of class X, meaning that the member functions of class Y have access to all the members of class X. Should the friend key word appear in class Y’s declaration or in class X’s declaration?
(2) Your member functions will be:
Make sure that the mutators for height and width only take positive numbers!
Test your class with the driver program given below.
//--- Test driver for class Rectangle
#include
using namespace std;
setHeight (int h): mutator for height variable
setWidth (int w): mutator for width variable
setDimensions (int h, int w): sets both height and width
getArea (): returns the area of the rectangle
getPerimeter () returns the perimeter of the rectangle
print (): prints a rectangle with your dimensions composed of asterisks
(3) Create a default constructor that sets the default values of Rectangle class to 1.
int main()
{
Rectangle rec rec2;
recl.setHeight (10);
recl.setWidth (20);
Page
rec2.setDimensions (5, 10);

Extend the definition of the class complexType so that it performs the subtraction and division operations. Overload the operators subtraction and division for this class as member functions. If (a, b) and (c, d) are complex numbers, (a, b) - (c, d) = (a - c, b - d), If (c, d) is nonzero, (a, b)/(c, d) = ((ac + bd)/(c ^2+ d ^2 ), (-ad + bc)/(c ^2 + d^ 2 )) b.

Program Information A friend has a point class that needs some help with its interface. You volunteer to help add operator overloading to the class. (No, really, you did. Don't you remember?) You decide to overload operators for the distance between two points (operator-), input (operator>>), output (operator<<), equality (operator==), and inequality (operator!=). After a bit of arguing, you decide to also overload for midpoint (operator/). You decide to also fix up your friend's class by adding operator= and 'missing' constructors. Don't forget to write a small test application to show that the class still works -- new operators and all!arrow_forward
