Answer to Question #50783 in C++ for zexy

Question

A. Create a class named Teacher that holds a Teacher’s first and last names and the grade
level the Teacher teaches. Include a constructor function that uses default first and last
names, such as “ZZZZZZZ” and a default grade level, such as 0, when no arguments are
provided.
B. Create a class named Student that hold’s a Student’s first and last names. Include a
constructor function that uses default first and last names, such as “ZZZZZZZ,” when no
names are provided.
C. Create a class named Classroom. A Classroom holds a Teacher and an array of 35
Student objects.
D. Create a class named School. A School contains an array of 100 Classroom objects.
(This class is being designed to be a very large class, to more quickly demonstrate running
out of memory.)

Answer 1

Program:
#include<iostream>
#include<string>
#define MAX_LEN 100

using namespace std;

class Teacher
{
private:
string firstName;
string lastName;
int grade;
public:
Teacher(string first="ZZZZZZZ",stringlast="ZZZZZZZ", int gr=0);
};

Teacher::Teacher(stringfirst,string last, int gr)
{
firstName=first;
lastName=last;
grade=gr;
}

class Student
{
private:
string firstName;
string lastName;
public:
Student(stringfirst="ZZZZZZZ",string last="ZZZZZZZ");
};

Student::Student(stringfirst,string last)
{
firstName=first;
lastName=last;
}

class Classroom
{
private:
Teacher teacher;
Student students[35];
};

class School
{
private:
Classroom classes[100];

};

int main()
{
School *mySchool;
mySchool=new School;
if(mySchool==NULL)
cout<<"Out of memory";
else
cout<<"We can use so big pieof memory!";
return 0;
}
