HOW do I    malloc or new    an array of complex numbers in  GNU C++  code ?
MALLOC does not work,   how do I use  MALLOC correctly or  NEW ?

I made a  struct called  complex  (for a complex number with realp and imagp)
And I want to make an array of   128 locations  (where each location includes a    realp and imagp)


Struct complex
{
Float  realp;
Float imagp;
}

//  tdin  is a pointer to an array of complex numbers
complex*  tdin;


//  form the array with  MALLOC  or whatever works in  GNU C++
tdin =  (complex*)  malloc ( 128 * sizeof (complex) );


then I can print the contents of the array with

for (int k;  k<128; k++)
{  cout << tdin[k].realp  <<  " and "  <<  tdin[k].imagp  << "endl";
