C++ Programming II Lab Lab Assignment 4

Overview:

This assignment is for the students to practice using inheritance in C++. ThestudentsneedtocompletetheEmployee, Professor, Studentclassesasshownbelow.

/** * Complete the Employee class, which is a derived class of the Person class */

class Employee { public: 

 // [[ Constructor to initialize jobTitle ]] 

 void print_info() { cout << name << " works as a " << jobTitle << "." << endl; 

}

protected:

 // [[ jobTitle ]] 

};

/** * Complete the Professor class, which is a derived class of the Employee class */

class Professor { public: 

// [[ Constructor to initialize department and course ]]

void print_info() { cout << name << " is a " << jobTitle << " in the " << department << "

department, teaching " << course << "." << endl; }

private:

 // [[ department ]] 

 // [[ course ]] 

};

/** * Complete the Student class, which is a derived class of the Person class */

class Student { public: 

 // [[ Constructor to initialize major ]] 

 void print_info() { cout << name << " is majoring in " << major << "." << endl; 

}

private:

// [[ major ]]

};

Requirements:

1) Complete the Employee class, Professor class and Student class following the comments in the code.

2) Compile and run the program and check whether the result is correct.

};

int main() {

Person person("Susan", 25, "female");

Employee employee("Bob", 30, "male", "human resource manager");

Professor professor("Alice", 40, "female", "professor", "computer science", "programming languages");

Student student("Ronald", 20, "male", "computer science");

person.print_info();

employee.print_info();

professor.print_info();

student.print_info();

return 0;

}

Correct Output

Susan is a 25 year old female. Bob works as a human resource manager. 

Alice is a professor in the computer science department, teaching programming languages.

Ronald is majoring in computer science.
