构造std::complex对象。

1%29由实部和虚部构造复数。

2%29复制构造函数。的内容的副本构造对象。other在标准的专门化中，复制构造函数是隐式的。

3%29转换构造函数从不同类型的复数构造对象。

参数

re-the real part
im-the imaginary part
other-another complex to use as source

另见

operator=assigns the contents (public member function)
operator""ifoperator""ioperator""il (C++14)A std::complex literal representing pure imaginary number (function)
