The real() function is defined in the complex header file. The real() function is used to find the real part of the complex number.
template<class T> T real(const complex<T>& z);
Parameter: This method takes a mandatory parameter z: which represents the given complex number.
Return: It returns the real part of the specified complex number.
Below programs illustrate the above function:-
Complex Number = (20.3, 4.9) Real part of the complex number is =20.3
Complex Number = (2, 2) Real part of the complex number is =2
