Thus, the following program computes box-car volumes as long as you type numbers; it stops when you type the control-d keychord.

#include  
double box_volume (double h, double w, double l) {return h * w * l;} 
main ( ) { 
  double height, width, depth; 
  while (cin >> height >> width >> depth) 
    cout << "The volume of a " 
         << height << " by " << width << " by " << depth 
         << " box car is " << box_volume (height, width, depth) 
         << endl; 
  cout << "You appear to have finished." << endl; 
} 
--- Data ---
10.5 9.5 40.0 
10.5 9.5 50.0 
--- Result --- 
The volume of a 10.5 by 9.5 by 40 box car is 3990 
The volume of a 10.5 by 9.5 by 50 box car is 4987.5 
You appear to have finished.
