complex::operator+=

여러 대상 복소수에 추가, 추가 된 복잡 한 수 같은 형식으로 추가 되어 복소수의 실수부와 허수부 부분 큽니다.

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

매개 변수

• _Right
  복잡 한 숫자 또는 숫자 대상 복잡 한 수의 매개 변수와 동일한 형식입니다.

반환 값

추가 매개 변수로 지정 된 번호를 가진 복잡 한 수 있습니다.

설명

데이터를 특정 형식으로 변환 하지 않고 간단한 산술 연산을 실행할 수 있도록 작업 오버 로드 됩니다.

예제

// complex_op_pe.cpp
// compile with: /EHsc
#include <complex>
#include <iostream>

int main( )
{
   using namespace std;
   double pi = 3.14159265359;

   // Example of the first member function
   // type complex<double> added to type complex<double>
   complex <double> cl1 ( 3.0 , 4.0 );
   complex <double> cr1 ( 2.0 , -1.0 );
   cout << "The left-side complex number is cl1 = " << cl1 << endl;
   cout << "The right-side complex number is cr1 = " << cr1 << endl;

   complex <double> cs1 = cl1 + cr1;
   cout << "The sum of the two complex numbers is: cs1 = cl1 + cr1 = "
        << cs1 << endl;

   // This is equivalent to the following operation
   cl1 += cr1;
   cout << "The complex number cr1 added to the complex number cl1 is:"
        << "\n cl1 += cr1 = " << cl1 << endl;

   double abscl1 = abs ( cl1 );
   double argcl1 = arg ( cl1 );
   cout << "The modulus of cl1 is: " << abscl1 << endl;
   cout << "The argument of cl1 is: "<< argcl1 << " radians, which is " 
        << argcl1 * 180 / pi << " degrees." << endl << endl; 

   // Example of the second member function
   // type double added to type complex<double>
   complex <double> cl2 ( -2 , 4 );
   double cr2 =5.0;
   cout << "The left-side complex number is cl2 = " << cl2 << endl;
   cout << "The right-side complex number is cr2 = " << cr2 << endl;

   complex <double> cs2 = cl2 + cr2;
   cout << "The sum of the two complex numbers is: cs2 = cl2 + cr2 = " 
        << cs2 << endl;

   // This is equivalent to the following operation
   cl2 += cr2;
   cout << "The complex number cr2 added to the complex number cl2 is:"
        << "\n cl2 += cr2 = " << cl2 << endl;

   double abscl2 = abs ( cl2 );
   double argcl2 = arg ( cl2 );
   cout << "The modulus of cl2 is: " << abscl2 << endl;
   cout << "The argument of cl2 is: "<< argcl2 << " radians, which is " 
        << argcl2 * 180 / pi << " degrees." << endl << endl;
