FAQ: How to test whether integer is even or odd

[giggsy]

Hi. I need to write a function that tests whether an integer is even or not. This is how far I've got. I wasn't sure if its best to use an 'if' statement in the function.

/* a function that tests whether an integer is even, returning a true or false
   answer */

#include <iostream>

using namespace std;

int main()
{
  int n = 0;

  cout << "Enter a number: ";
  cin >> n;

  cout << test(n) << endl;

  return 0;
}

int test(int n)
{
  if (n

cheers.
