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.。

#include <complex>
#include <iostream>

   cout << "The modulus of cs1 is: " << abscs1 << endl;

   // Example of the third member function
   // type double plus type complex<double>
   double cl3 = 5.0;

   // 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 );
