Constructed class in constructed class

[Apoapsis]

Quick question. Suppose I have a class:

class data {
public:
	double x, y, z, blah;
	data ();
};

with the constructor:

data::data () {
	x = 0;
	y = 0;
	z = 0;
	blah = 1;
}

In another class (and constructor), the data class is used:

class otherclass {
public:
	// other variables
	data moardata;
otherclass () {
	//constructing class
}
};

would I need to construct moardata.x, moardata.y, etc if I wanted them to be zero? Or would the constructor for data affect each member declared in otherclass?

Thanks!

Yes. Your data constructor would set them all to zero for each otherclass.

No. On creating an object of otherclass, the default constructor of the class data will be called which already does what you want to.
