In C++, a good minimum function would be
template <typename T>
inline T
min(const T& a, const T& b)
{
return (a < b) ? a : b;
}
which would make an inline minimum statement with only one evaluation
for a and b, plus a single copy operation for the return. Plus, its
typesafe, only comparing items of the same type.
