operator<< (<complex>)
复数指定插入到输出流。
template<class Type, class Elem, class Traits>
basic_ostream<Elem, Traits>&
operator<< (
basic_ostream<Elem, Traits>& _Ostr,
const complex<Type>& _Right
);
参数
_Ostr
复数输入的输出流。_Right
将进入的复数到输出流
返回值
写入指定的复数的值到解决格式的 _Ostr :( 实部和虚部, )。
备注
输出流重载,以便它接受它的所有形式,因此,默认输出格式是解析格式。
示例
// complex_op_insert.cpp
// compile with: /EHsc
#include <complex>
#include <iostream>
int main( )
{
using namespace std;
double pi = 3.14159265359;
complex <double> c1 ( 3.0 , 4.0 );
cout << "Complex number c1 = " << c1 << endl;
complex <double> c2 ( polar ( 2.0 , pi / 6 ) );
cout << "Complex number c2 = " << c2 << endl;
// To display in polar form
double absc2 = abs ( c2 );
double argc2 = arg ( c2 );
cout << "The modulus of c2 is: " << absc2 << endl;
cout << "The argument of c2 is: "<< argc2 << " radians, which is "
<< argc2 * 180 / pi << " degrees." << endl << endl;
}
