Declaration

complex<double>::complex(double dReal = 0, double dImag = 0);

Description

This is the constructor for the complex number class template specialization for the double type.

Header Include

#include <complex>

Overloads

complex(const complex<double>& kqrComplex);

explicit complex(const complex<long double>& kqrComplex);

Example

#include <complex>
#include <iostream>

int main()
{
	using namespace std;

	// Create a complex number
	complex<double> qComplex(2.0, 4.0);
	cout << "Complex Number : "<< qComplex << endl;

	// Create a complex number with the copy constructor
	complex<double> qCopy(qComplex);
	cout << "Copy of Complex Number : "<< qCopy << endl;

	// Keep the window open
	cin.get();
	return 0;
}
