In-Depth Information
Methods aren't the only things that C++ allows us to overload. We can also overload operators,
which allows us to use our classes like the built-in types.
Operator Overloading
Listing 8-11 shows our
player
class with an overloaded
+=
operator.

void operator+=(const std::string&
name)
{
m_name.append(name);
