7.8.3.Return a value from a function

#include <iostream> 

using namespace std; 

 

int box(int length, int width, int height); // return the volume 

 

int main() 

{ 

  int answer; 

 

  answer = box(10, 11, 3); // assign return value 

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

 

  return 0; 

} 

 

// This function returns a value.  

int box(int length, int width, int height) 

{ 

  return length * width * height ; 

}

The volume is 330
