b. Create a class named Student that holds a Student's first and last name. include a constructor function that uses default first and last names, such as "ZZZZZZZ", when no names are provided.
c. Create a class name 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.
e. In a main() demonstration function, declare a pointer to an array of 500 School objects and include code to handle any memory allocation errors that occur. in a loop, declare 500 array objects at a time, continuing to rewrite the main() functions if necessary until you create enough School objects to cause a memory allocation exception. when memory is exhausted, display an appropriate message and terminate the application. save the file as school.cpp

int gradeLevel;
Teacher(string fName, string lName, int grade){

}
Teacher(){
firstName = "ZZZZZ";
lastName = "ZZZZZ";
gradeLevel = 0;
}
};
class Student{
public:
string firstName, lastName;

Student students[35];
public:
ClassRoom(Teacher t, Student[] s){

teacher.lastName = t.lastName;
teacher.gradeLevel = t.gradeLevel;
for(int i=0;i<35; i++)
students[i].firstName = s[i].firstName;
studetns[i].lastName = s[i].lastName;
}
};
class School{
public:

};
int main(){
try{
while(1){
School *schools = new School[500];
}
}
catch (exception& e){
