Example: An implementation of += for strings. When concatenating strings, it is useful to know the length in advance so as to allocate memory only once.

String& String::operator+=( const String& rhs ) {

 // … implementation …

 return *this;
}

String operator+( const String& lhs, const String& rhs ) {
 String temp;                                 // initially empty
 temp.Reserve( lhs.size() + rhs.size() );     // allocate enough memory
 return (temp += lhs) += rhs;                 // append the strings and return
}
