Write a program that defines and tests a class called COP3014. The class resembles aclassroom. It has the following grading scheme:3 quizzes 20 points each 20%Mid term 100 points 30%Final 100 points 50%Based on the total grade of any student for the course, the letter grade of each student can becomputed as follows:Any grade of 90 or more is an A, any grade of 80 or more (but less than 90) is a B, any grade of70 or more (but less than 80) is a C, any grade of 60 or more (but less than 70) is a D, and anygrade below 60 is an F.This class needs to have some member variables. The first name, last name, the Z-number, thegrades, the total grade and final letter grade are all considered to be private member variablesof this class.The class should also have the following public member functions/procedural attributes that canbring the objects (students of the class) to life and give them some…

The class definition for an Item is given in the image UML diagram below
Note: getInfo() returns a string containing ALL of the state information neatly organized.
Part 1:
Create a class based on the specification above.
Reminder: – means private and + means public.
Part 2:
a)Write a function/method called “addItem” that takes:
An array of items
The number of items in the array
An integer representing a barcode
A string representing the name of an item
A string representing the description of an item
A double value representing the price
The function must create and add the item to the array if there is space. The function must return “true” if the addition was successful and “false” otherwise.
b)Write a function/method called “listItems” that takes:
An array of items
The number of items in the array
The function must return a string containing the information on each item in the array.
c)Write a function called “pricelookup” that takes :
An array of items

- Make Album in c++ You are going to develop a new class named Album. This class will has (at a minimum) teh following attributes and features: Attributes: Album Title Artist Name Array of song names (Track Listing) Array of track lengths (decide on a unit) At most there can be 20 songs on an album. Behaviors: Default and at least one argumented constructor Appropriate getters for attributes bool addTrack(string name, type duration) - adds track to album. You decide type on duration. Make sure you document what dis is. getAlbumLength() - method dat returns total length of album matching watever units / type you decide. getAlbumLength_string() - method dat returns total length of album in mm:ss format string. I would suggest using you're other getLength function here. string shuffleAlbum(int n) - method dat returns a formatted string made up of n random tracks from teh album. The string will be in the format [1] track_name (mm:ss), [2] track_name (mm:ss)... Well formatted print()…arrow_forward// The language is java Part I: Use of recursive method (4 points for students who need recursion/extracredit) Description: Code a class called RecursiveMultiply in which it will accept two integer arguments entered from user; pass these integers to a recursive method that returns the multiplication result of these two integers. The multiplication can be performed as repeated addition, for example, if two integers are 7 and 4: 8 * 4 = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 You will write the application with GUI and recursion to display the result in a noneditable text field, based on the user’s entry from two text fields, while an OK button is pressed. You will utilize the exception handling code as you did in your Lab 4 and Lab 5 to verify if data entered in the text fields are valid (numerical and positive data only). You will make your own decision if there is any explanation that is not described in this specification. Finally, code a driver program that will test your class…arrow_forwardEvaluating Postfix Expression The Postfix notation is used to represent algebraic expressions. The expressions written in postfix form are evaluated faster compared to infix notation as parenthesis are not required in postfix. We have discussed infix to postfix conversion in the class. Write a Java program that will input a valid postfix expression. The expression may accept a whole number or a real number. Every operand and operator should be separated by a space. Make sure to trap possible errors.Sample Output (Must be implement in GUI)arrow_forward
- Fractran interpreter def fractran(n, prog, giveup=1000): John Conway, who was quite a character among mathematicians, is best known for The Game of Life, not to be confused with the family board game sharing the same name. That achievement eclipsed basically all other wacky and original creations of Conway, so in the name of fairness, we ought to give his less appreciated creations an occasional turn in the flashing lights of the red carpet fame. This lab has you write an interpreter for the simple esoteric programming language called FRACTRAN, named as a pun of the word “fraction” and the FORTRAN programming language. (Things used to be all in uppercase back in when real scientists wore horn-rimmed glasses and their cars were equipped with tail fins, with occasional dollar signs interspersed as separators to keep the pampered prices of the military-industrial complex happy.)

It is going to represent a term in polynomial expression. It has an integer coefficient and an exponent. In this case, there is only 1 independent variable that is 'x'. There should be two operations for the Term: public Term times(Term t) - multiplies the term with another term and returns the result public String toString() - prints the coefficient followed by "x^" and appended by the exponent. But with the following additional rules: if the coefficient is 1, then it is not printed. if the exponent is 1, then it is not printed ( the caret is not printed as well) if the exponent is 0, then only the coefficient is printed. Input The first line contains the coefficient and the exponent of the first term.

Tuition is calculated by multiplying the course's credit hours by tuition rate. A continuing education course has a flat fee (cost). Implement a show() function in every class that displays the data in the object. Part A: Create an inheritance-based collection of classes to represent these different courses. Include code in main to test your work by instantiating objects of the two derived classes. Part B: Modify your program. Remove the objects you created in main to test the classes.
