Classes with Arrays using other class objects - c++

Question

I have two completed classes at the moment, the Teacher and Student classes have default definitions.
Right now I am trying to figure out the Classroom and School classes. The Classroom class is supposed to hold a Teacher and an array of 35 Student objects.
The School class is supposed to contain an array of 100 Classroom objects.
How do I do this, I sort of know how to initialize an array in a class but I'm not sure how to achieve this using the objects of another class?
class Teacher
{
private:
string last;
string first;
int gradeLevel;
public:
Teacher();
};
Teacher::Teacher()
{
last = "AAAA";
first = "BBBB";
gradeLevel = 0;
}
class Student
{
private:
string studLast;
string studFirst;
public:
Student();
};
Student::Student()
{
studLast = "AAAA";
studFirst = "BBBB";
}
class Classroom
{
};
class School
{
};

Answer 1

For example:
class Classroom
{
private:
Teacher t; // create a teacher
Student s[35]; // create an array of 35 students
...
};
class School
{
private:
Classroom rooms[100]; // create an array of 100 rooms
...
};

Answer 2

What you want to do here is create a Teacher, just one like you wanted, and then create an array of Student objects, which if you didn't know is done like Student students[35];. Then to the School object which is just an array of Classroom objects. Here is the full code:
class Classroom
{
private:
Teacher teacher;
Student students[35];
public:
Classroom();
};
Classroom::Classroom()
{
;
}
class School
{
private:
Classroom classrooms[100];
public:
School();
};
School::School()
{
;
}
Note: all of the items in the arrays are initialized when you write something like Student students[35];. You can check this by doing cout << this->stduents[12].studLast << endl;
