Finding out which integer is smallest

[sunburnt]

Find the minimum of two values; then find the minimum of your selected minimum and the other value.

If you had a function MIN(a,b) which returned the lesser of two values:

int a, b, c;

min = MIN(a, b);
min = MIN(min, c);

// min is the minimum value.

your min function might do this:

if (a < b)
  return a; // a is less than b
else
  return b; // b is less than a OR a = b (they are both the 'min')

Hope this helps!
