7.8.4.Return a double value from a function

#include <iostream> 

using namespace std; 

 

double box(double length, double width, double height); // use double data 

 

int main() 

{ 

  double answer; 

 

  answer = box(10.1, 11.2, 3.3); // assign return value 

  cout << "The volume is " <<  answer; 

 

  return 0; 

} 

 

// This version of box uses double data. 

double box(double length, double width, double height) 

{ 

  return length * width * height ; 

}

The volume is 373.296
