declare array in a class

[mickey]

Hi, I'd like declare float spec[4]; as private member of a class; my problem is that I need do something about this (declare and initialize but inside declare of class seems not possible):

float spec[]={.4f,.4f,.4f,1};

float spec[]={.4f,.4f,.4f,1};

To copy to clipboard, switch view to plain text mode 

I tried declare

class myClass {
   float spec[4];
};
 
myClass::myClass() {
      spec[]={.4f,.4f,.4f,1};
}

class myClass {
   float spec[4];
};

myClass::myClass() {
      spec[]={.4f,.4f,.4f,1};
}

To copy to clipboard, switch view to plain text mode 

but this get an error;
Do I make a for cicle to initialize spec???? Thanks
