OOP constructor question

How can a class constructor initilize a member variable or a class array? dose it have to do with the 'this' operator?

struct default{
default();
float num;
}def[4];

default::default() {
?????
}

You could give the struct constructor a default argument -

Code:

---

struct defaulty{
defaulty(float n =10);
float num;
}def[4];

defaulty::defaulty(float n){
        num=n;
}

---

You'll also want to change the name of your struct, as default is a revserved keyword.

Yes but how do i initilize the members of each object. Do i have to make implicit calls.

default::default() {
def[0].num = 0;
def[1].num = 0;
def[2].num = 0;
def[3].num = 0;
}

in zens example its already done.
struct defaulty{
defaulty(float n =10);
float num;
}def[4];

the def[4] defines an array of 4 defaulty structs. for each struct the constructor will have been called with the default value so therefore it is initialised.
