operator+ (<complex>)
2 個の複雑な、1 を行うか、実際という部分の型のサブセットに属する場合があります。
template<class Type>
complex<Type> operator+(
const complex<Type>& _Left,
const complex<Type>& _Right
);

const Type& _Right
);
template<class Type>
complex<Type> operator+(

パラメーター
_Left
2 個の複雑な + または操作によって追加される複素数のパラメーターの型である数の狭い。_Right
2 個の複雑な + または操作によって追加される複素数のパラメーターの型であるの 2 番目の数値。
戻り値
値および型をパラメーターで指定した 2 個の数値の追加に発生する複素数になります。
解説
操作は簡単な算術演算が特定の形式のデータへの変換なしで実行できるようにオーバーロードされます。単項演算子は、を返します _Left.
