Programming apti Assignment- 2

Main.cpp

// Question 1: Consider the scenario where 6 professors are training a bunch of 63 students on 6 programming languages(Java, C, Python, CPP, C_Hash, R).
// Deploy the scenario in the interactive mode and perform several tasks using the constraints and conditions below,

// Student has following properties:
// Attributes -> name, age, usn, cgpa(avg. of 6 programming language scores), favProfName, favPrgLang
// Methods -> getters() and setters() for reading and retrieving data, readStudent() for deploying setters, showStudent() for displaying student details by deploying getters.


// Professor has following properties:
// Attributes -> name, age, profId, salary, favStudentName, progLangHandling, rating
// Methods -> getters() and setters() for reading and retrieving data, readProf() by deploying setters, showProf() for displaying details by deploying getters.

// Implement the following functions,
// * Function to find top scorer of individual programming language by taking language as input
// * Function to display the student’s favourite Professor’s details by taking student name as input(friend function as bridge between two classes)
// * Function to provide rating to professors by taking professor id as input parameter(Only one chance for each student to rate each of 6 professors) -> 1: Good 2: Better 3: Best 4: Excellent 5: Awesome
// * Function to find top rated professor
// * Function to find top scorer of class
// * Function to find the average score of class (Overload + operator to add the individual student cgpa)cout<<"Enter the number of students : ";
// * Show the count of students who have preferred a particular programming language by taking it as input
// Note: 
// * Data Members have private access specifier 
// * Additional attributes and methods to individual classes can be added if necessary 
// * Implement the tasks in menu driven fashion
// * Program has to be interactive and soft coded
