// Fig. 8.6: fig08_06.cpp
// Cube a variable using pass-by-value.
#include <iostream>
using std::cout;
using std::endl;

int cubeByValue( int ); // prototype

int main()
{
   int number = 5;

   cout << "The original value of number is " << number;

   number = cubeByValue( number ); // pass number by value to cubeByValue
   cout << "\nThe new value of number is " << number << endl;
   return 0; // indicates successful termination
} // end main

// calculate and return cube of integer argument
int cubeByValue( int n )
{
   return n * n * n; // cube local variable n and return result
} // end function cubeByValue
