Need help with valarray. Here is my code:

#include <valarray>
#include <complex>

typedef std::complex<double> Complex;
typedef std::valarray<Complex> CArray;

//some code

CArray *abc = new CArray(10);
Complex mem = abc[5]; //Error here

It complaints that there are no suitable conversion from CArray to Complex. Why it tries to return something of CArray type?! Thanks in advance

P.S.

'std::valarray<Complex>::operator[]' non-standart syntax; use'&' to create a pointer to member

Why are you dynamically allocating your valarray? It is (almost|always) never a good thing to do. – SergeyA Jan 24 '17 at 15:38

I very much doubt that "non-standart syntax" is part of the actual error message. Please use copy & paste. – Christian Hackl Jan 24 '17 at 15:43
@SergeyA that helped. Actually i totally forgot about resize method – user2090826 Jan 24 '17 at 15:52
