Write a complete program that prompts the user for the radius of a sphere, and calculates and prints the volume of that sphere. Use an inline function sphereVolume that returns the result of the following expression: (4.0 / 3.0 * 3.14159 * pow(radius, 3)).

Question

What will be an ideal response?

Answer 1

See the following program:
```
// Inline function that calculates the volume of a sphere.
#include
#include
using namespace std;

const double PI = 3.14159; // define global constant PI

// calculates volume of a sphere
inline double sphereVolume( const double radius )
{
return 4.0 / 3.0 * PI * pow( radius, 3 );
} // end inline function sphereVolume

int main()
{
double radiusValue;

// prompt user for radius
cout << "Enter the length of the radius of your sphere: ";
cin >> radiusValue; // input radius

// use radiusValue to calculate volume of sphere and display result
cout << "Volume of sphere with radius " << radiusValue
<< " is " << sphereVolume( radiusValue ) << endl;
} // end main
```
