You can, for example, define one display_box_car_volume function that handles integers, and another display_box_car_volume function that handles floating-point numbers:

// Define integer display_box_car_volume function: 
void display_box_car_volume (int h, int w, int l) { 
  cout << "The integer volume of the box car is " 
       << h * w * l 
       << endl; 
} 

// Then, define floating-point display_box_car_volume function: 
void display_box_car_volume (double h, double w, double l) { 
  cout << "The floating-point volume of the box car is " 
       << h * w * l 
       << endl; 
} 

Then, you can put both functions to work in the same program:

#include   
// Define integer display_box_car_volume function here 
// Define floating-point display_box_car_volume function here 
// Then, define main: 
main ( ) { 
  int int_height = 11,  
      int_width = 9, 
      int_length = 40; 
  double double_height = 10.5, 
         double_width = 9.5, 
         double_length = 40.0; 
  display_box_car_volume (int_height, int_width, int_length); 
  display_box_car_volume (double_height, double_width, double_length); 
} 
--- Result --- 
The integer volume of the box car is 3960 
The floating-point volume of the box car is 3990
