Project IV [After Chapter 6]

Add a date last modified note to include the date you made changes:

Add lines the menu as follows

“ Enter 5 to find the volume and area of a box.”

“Enter 6 to find the volume and area of a sphere.”

Change the validation check to allow 5 and 6 to be valid.

Define double variables length, width, height for use in the calculations for a box.

Define double boxVolume and boxArea for use in the calculations for a box.

Define double variables radius, sphereVolume, and sphereArea for use in the calculations for a sphere.

Enter code to test for choice = 5 and execute code similar to choices 1 and 2 for C to F and cm to inches that does this:

Ask for a length for a box

Ask for a height for a box

Ask for a width for a box

boxVolume = box ( 1, length, width, height); 1à calculate volume of box using the length, width, height of the box.

Call the same function box with these parameters boxArea = box(2, length, width, height),

The 2 à that the total area of the box is to be calculated.

Display to the user a message similar to this “A box “ + length + ”by “ + width

“by ” height + “ has a volume of“ + boxVolume);

Display to the user a message similar to this “”A box “ +length + “by “ + width + “by “ +height + “ has an area of “ + boxArea);

Enter code to test for choice = 6 and execute code similar to choices 1, 2 and 3 for C to F and cm to inches and radians to degrees that does this:

Ask for the radius of the sphere.

sphereVolume = sphere (1, radius); 1 à indicates that a volume is to be calculated.

sphereArea = sphere (2, radius); 2 àindicates that area is to be calculated.

Display to the user a message similar to this “ A sphere of radius = “ + radius

+ “ has a volume = “ + sphereVolume);

Display to the user a message similar to this “A sphere of radius = “ + radius

+ “ has an area = “ + sphereArea );

Create the function double box (int what, double len, double wid, double ht)

Define double result;

If what == 1)

If (what == 2)

Return result

End function.

Create a function double sphere ( int what, double radius)

Define double result;

If what == 1)

result = 4.0/3.0 * 3.14159 * Math.pow(radius,3) ; // calculate the volume of the sphere.

If (what ==2)

result = 4* 3.14159 *Math.pow( radius,2);// Calculate the area of the sphere

Return result

End function.

Explanation / Answer

#include <iostream>
#include <cmath>
using namespace std;

double sphere( int what,double radius)
{
double result;
if (what == 1)
result = 4.0/3.0 * 3.14159 * pow(radius,3) ; // calculate the volume of the sphere.
else if (what ==2)
result = 4* 3.14159 *pow( radius,2);// Calculate the area of the sphere
return result;
}

double box (int what, double len, double wid, double ht)
{
double result;
if (what == 1) result = len*wid*ht;
if (what == 2) result = 2*(len*wid+wid*ht+ht*len);
return result;
}

int main() {

double length, width, height;
double boxVolume, boxArea ;
double radius, sphereVolume, sphereArea;

cout<<"Enter length of box : ";
cin>>length;
cout<<" Enter height of box : ";
cin>>height;
cout<<" Enter width of a box : ";
cin>>width;
boxVolume = box(1, length, width, height);

boxArea = box(2, length, width, height),

cout<<" A box " << length << " by " << width <<" by "<< height << " has a volume of " << boxVolume;

cout<<" A box " <<length << " by " << width << " by " <<height << " has an area of " << boxArea;

cout<<" Enter radius of the sphere";
cin>>radius;
sphereVolume = sphere (1, radius);
sphereArea = sphere (2, radius);

cout<<" A sphere of radius = " << radius << " has a volume = " << sphereVolume;
cout<<" A sphere of radius = " << radius<< " has an area = " << sphereArea ;

return 0;
}

Output:

Enter length of box :3.5
Enter height of box :6.7
Enter width of a box :7.2
A box 3.5 by 7.2 by 6.7 has a volume of 168.84
A box 3.5 by 7.2 by 6.7 has an area of 193.78
Enter radius of the sphere 5.5
A sphere of radius = 5.5 has a volume = 696.909
A sphere of radius = 5.5 has an area = 380.132
