Question

C++ code

Write a program to illustrate how to use the temporary class. Your program must contain statements that would ask the user to enter data of an object and use the setters to initialize the object.

Use three header files named main.cpp, temporary.h, and temporaryImp.cpp

An example of the program is shown below:

Enter object name (rectangle, circle, sphere, or cylinder: circle

Enter object's dimensions: 
    rectangle (length and width) 
    circle (radius and 0) 
    sphere (radius and 0) 
    rectangle (base raidus and height) 
10
0


After setting myObject: 
circle: radius = 10.00, area = 

Answer 1

// Temporary.h

#include<iostream>
using namespace std;

class Rectangle                                 // Rectangle Class
{
   float length, width;
public:
  
   void setValues(float len, float wid);
   void printValues();
};

class Circle                                      // Circle Class
{
   float radius,area;
public:
   void setValues(float radius, float area);
   void printValues();
};
class Sphere                                           // Sphere Class
{
   float radius, area;
public:
   void setValues(float radius, float area);
   void printValues();
};
class Cylinder                                  // Cylinder Class
{
   float radius, height;
public:
   void setValues(float radius, float height);
   void printValues();
};

OUTPUT :

Enter object name (Rectangle, Circle, Sphere or Cylinder):circle
Enter object's dimensions:
10
0
circle: radius = 10, area = 0

Explanation :

I have done object creation as per user input and initialize values to member of that class, display those values. i didnt do any calculation operation. if any help need, plz comment.
