Bir hedef karmaşık sayı bir sayı ekler, eklenen sayı karmaşık olabilir ve aynı türde olduğu için onu eklenir karmaşık sayının reel ve sanal kısımları olur.

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

Parametreler

_Right
Karmaşık bir sayının veya aynı tür hedef karmaşık sayının parametresi olarak bir sayı.

Dönüş Değeri

Eklenen bir parametre tarafından belirtilen sayı olan karmaşık sayı.

Notlar

Böylece belirli bir biçimde veri dönüştürme olmadan basit aritmetik işlemleri yürütülen işlem aşırı yüklendi.
