Getting different output when calling the same FFT functions of MKL from C++ and Fortran

I got different results when calling same functions of MKL from intel C++ compiler and IVF separately. I'm in windows 10 64bit, and VS 2013. My C++ code is as follows:

#include <complex>
#include <iostream>
#include "mkl_dfti.h"
int main()
{
 using namespace std;
 complex <float>x[32];
 int  i;
 DFTI_DESCRIPTOR_HANDLE my_desc1_handle;
 MKL_LONG status;

 for (i = 0; i < 32; i++)
 {
  x[i] = ((i+1)*1.0, (i+1)*1.0);
 }

 status = DftiCreateDescriptor(&my_desc1_handle, DFTI_SINGLE, DFTI_COMPLEX, 1, 32);
 status = DftiCommitDescriptor(my_desc1_handle);
 status = DftiComputeForward(my_desc1_handle, x);
 status = DftiFreeDescriptor(&my_desc1_handle);

 for (i = 0; i < 32; i++)
 {
  cout << x[i] << endl;
 }

 return 0;
}

My fortran code is as follows:

PROGRAM MAIN
    USE MKL_DFTI
    IMPLICIT NONE
    Complex :: X(32)
    INTEGER ::   I
    type(DFTI_DESCRIPTOR), POINTER :: My_Desc1_Handle
    Integer :: Status
    DO I=1,32
        X(I)=CMPLX(1d0*i,1d0*i)
    END DO
    Status = DftiCreateDescriptor( My_Desc1_Handle, DFTI_SINGLE, DFTI_COMPLEX, 1, 32 )
    Status = DftiCommitDescriptor( My_Desc1_Handle )
    Status = DftiComputeForward( My_Desc1_Handle, X )
    Status = DftiFreeDescriptor(My_Desc1_Handle)
    DO I=1,32
        write(*,*)x(i)
    END DO
    END

And results from these two programs are listed in the following columns. Left from C++, and right column from fortran.

Could someone enlighten me on this? I'm really obsessed with it. Thanks
