operator+ (<complex>)

添加两个复数，或者这两者可能属于类型子集物理和虚部的集合。

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

参数

• _Left
  是它的参数类型将由添加 + 操作的第一个复数或数字。

• _Right
  是它的参数类型将由添加 + 操作的第二个复数或数字。

返回值

由两个数字值和添加类型由参数指定的复数输入。

备注

重载以便操作，简单算术操作来执行，而无需转换为特定数据的格式。 一元运算符返回 _Left.。

// complex_op_add.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> plus type complex<double>
   complex <double> cl1 ( 3.0 , 4.0 );
   complex <double> cr1 ( 2.0 , 5.0 );
   complex <double> cs1 = cl1 + cr1;

   cout << "The left-side complex number is cl1 = " << cl1 << endl;

   cout << "The sum of the two complex numbers is: cs1 = " << cs1 << endl;

   double argcs1 = arg ( cs1 );
   cout << "The modulus of cs1 is: " << abscs1 << endl;
   cout << "The argument of cs1 is: "<< argcs1 << " radians, which is " 
        << argcs1 * 180 / pi << " degrees." << endl << endl;

   double abscs2 = abs ( cs2 );
   double argcs2 = arg ( cs2 );
   cout << "The modulus of cs2 is: " << abscs2 << endl;
   cout << "The argument of cs2 is: "<< argcs2 << " radians, which is " 
        << argcs2 * 180 / pi << " degrees." << endl << endl;

   // Example of the third member function
   // type double plus type complex<double>
   double cl3 = 5.0;
   complex <double> cr3 ( 3.0 , 4.0 );
   complex <double> cs3 = cl3 + cr3;

   cout << "The left-side complex number is cl3 = " << cl3 << endl;

   double argcs3 = arg ( cs3 );
   cout << "The modulus of cs3 is: " << abscs3 << endl;
   cout << "The argument of cs3 is: "<< argcs3 << " radians, which is " 
        << argcs3 * 180 / pi << " degrees." << endl << endl; 

   // Example of the fourth member function
   // plus type complex<double>
   complex <double> cr4 ( 3.0 , 4.0 );
   complex <double> cs4 = + cr4;

   cout << "The right-side complex number is cr4 = " << cr4 << endl;
   cout << "The result of the unary application of + to the right-side"
        << "\n complex number is: cs4 = " << cs4 << endl;
   double abscs4 = abs ( cs4 );
   double argcs4 = arg ( cs4 );
   cout << "The modulus of cs4 is: " << abscs4 << endl;
   cout << "The argument of cs4 is: "<< argcs4 << " radians, which is " 
        << argcs4 * 180 / pi << " degrees." << endl << endl;  
}
