NOTE: It is REQURED that Each program must include this line:

cout << “Name: YOURNAME – Program Name: PROGRAM NAME – Date: MMDDYY” << endl;

* Be sure to add your name as a cout in the first lines of each program – else 0 credit.

* Add constructors – a default and parameterized constructor to each.

* Write an .h interface and a .cpp implementation for each class

* Write an Drive/Test file that tests the constructors and functions

* Write a UML class diagram for each class

Program 6 BOX – Complete the following code then run it

– Produce the correct output and Turn it in for credit

– Note: A Box is a 3D object…

Write a class for a BOX (box is another name for a cube)

It should contain: Width, Height, and Depth

It should contain 3 methods to input/set the Width, Height, and Depth Values.

It should contain a method to calculate the Volume of the box.

It should contain a method to calculate sum of the Area the 6 sides of the box,.

It should contain three method to return/get the individual values of the Width, Height and Depth variables in the class

All dimensions must be greater than zero, before the area or volume can be calculate… the calc functions should cout an error message is they are not.

Test the box with the following driver code:

HINT: Use function names and class name found in driver below.

int main() {

// Box 1 – Test set functions, Volume, getHeight and area functions

box B1;    // HINT MAKE A Default constructor or set functions…

B1.setWidth(2);

B1.setHeight(3);

B1.setDepth(4);

cout << “Height = ” << B1.getHeight << endl;

cout << “Area = ” << B1.calcArea() << endl;

cout << “Volume = ” << B1.calcVolume() << endl;

// Box 2 – Test zero value error for calc Area and Volume of sides functions

box B2;

B2.setWidth(3);

B2.setHeight(4);

cout << “Depth = ” << B2.getDepth << endl;

cout << “Area = ” << B2.calcArea() << endl;

cout << “Volume = ” << B2.calcVolume() << endl;

}

Expert Answer

 

Note:- I have changed the test driver program as there are some errors in calling the getters.

#include <iostream>

#include <cmath>

#include<iomanip>

using namespace std;

class box {

public:

float height=0; // height of a box

float width=0; // width of a box

float depth=0; //depth of a box

 

//methods to input/set the Width, Height, and Depth Values.

void setWidth(float w){

width=w;

}

 

void setHeight(float h){

height=h;

}

 

void setDepth(float d){

depth=d;

}

 

//methods to return/get the individual values of the Width, Height and Depth variables

 

float getWidth(void){

return width;

}

 

float getHeight(void){

return height;

}

 

float getDepth(void){

return depth;

}

 

//method to calculate the Volume of the box

float calcVolume(void){

if(width>0 && height>0 && depth>0){

return width*height*depth;

}else{

cout << “All the dimensions should be greater than zero “;

}

}

 

//method to calculate sum of the Area the 6 sides of the box

float calcArea(void){

if(width>0 && height>0 && depth>0){

return 2*(width*height+width*depth+height*depth);

}else{

cout << “All the dimensions should be greater than zero “;

}

}

};

//Test program used

int main() {

// Box 1 – Test set functions, Volume, getHeight and area functions

box B1; // HINT MAKE A Default constructor or set functions…

B1.setWidth(2);

B1.setHeight(3);

B1.setDepth(4);

cout << “Height = ” << B1.getHeight() << endl;

cout << “Area = ” << B1.calcArea() << endl;

cout << “Volume = ” << B1.calcVolume() << endl;

// Box 2 – Test zero value error for calc Area and Volume of sides functions

box B2;

B2.setWidth(3);

B2.setHeight(4);

cout << “Depth = ” << B2.getDepth() << endl;

cout << “Area = ” << B2.calcArea() << endl;

cout << “Volume = ” << B2.calcVolume() << endl;

}
