Re: C++ Primer ex 7.5

as usual , advices for improvement:

/* C++ Primer - 4/e
 *
 * exercise 7.5
 * STATEMENT:
 * write a funtion that take an int and a pointer to an int and
 return the larger of the values. What type should you use for the
 pointer ?
 */

#include <iostream>
#include <cassert>

/* we will use pointer to a const because we are interested in
   only reading the values */
int return_bigger( int i, const int* ip) {
  if( i > *ip )
    {
      return 1;
    }
  else if( i < *ip )
    {
      return -1;
    }
  else
    {
      return 0; /* if both vales are equal.t his will return Zero */
    }
}

int main()
{
  std::cout << "enter an initeger: ";
  int i;
  std::cin >> i;

  std::cout << "enter an initeger: ";
  int j;
  std::cin >> j;

  const int* pj = &j;

  std::cout << "is "
        << i
        << " bigger than "
        << j
        << ":\t"
        << (return_bigger( i, pj ))
        << std::endl;

  return 0;

}
