declare array in a class

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):

Code:

---

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

---

I tried declare

Code:

---

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

---

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

What error do you get ?

If your variable is static then use :

Code:

---

float myClass::spec[] ={...}

---

otherwise remove the "[]" in the initialisation.

my variabile is not static; but I have only instance of myClass in my program...and the only one instace of spec.....
I know that I can init an array with '{ }' only when I declare it....

If I declare it static is OK; but I'd like to do it not static:

if I remove [] from initialization 'spec = {1,2,2,0};' , get an error:

Code:

---

error C2059: syntax error : ']'
error C2143: syntax error : missing ';' before '{'
error C2143: syntax error : missing ';' before '}'

But is it possible to do this? Thanks

In the constructor you will have to declare each element of you array seperately.

Code:

---

spec[0]=.4f;
spec[1]=.4f;
spec[2]=.4f;
spec[3]=1;

---

of course you could employ a loop to make it easier.

You might then want to develop a constructor that will receive the values in as four arguments.

I hoped there was a way to don't inittialize array element serarately or with for.....
Thanks
