C++ Project

The following is a simple implementation of the circular queue

Important: for this project, you must complete the work based on this initial code.

1. Fix the full() method.

2. Fix the empty() method.

3. Place "X" in the front position using a statement in the constructor.

4. Adjust the DEQ() method so that the front position in the array would always have "X" in it and

the previous X should be blanked out.

5. Write the code for displayArray() method in a such a way that it should display the contents of the

Queue as shown in the array, from location 0 up to and including the last position.

6. Write the code for displayLine() method in a such a way that it should display the contents of the

Queue, from the rear position to the front position as in a waiting line.

Create a class named _MyArrays which has a main( ) and other static methods.

Part I (30%) [Main method] In the main() - Request the number of reviewers (r) and movies (m) - Declare a r x m two-dimensional array of integers - Allow the user to enter distinct values , row by row to fill the two dimensional array - Display the two-dimensional array using a _displayArray method. - Using the _printHighestLowestMovieRating method print the highest and lowest rating for each movie. - Using the _printAverageReviewerRating method print the average reviewer rating for each reviewer. - Test your program with the information in the example on the first page.

Part II (20%) [_displayArray] The _displayArray method must have the following specifications and functionality: o Only Takes the two-dimensional array as a formal parameter/argument o Displays the array data as a matrix (i.e. Rows and Columns) ( you know how to find the row and column without (r ) and (m) ) o Does not return any value.

Part III (20%) [_printHighestLowestReviewerRating] The _ printHighestLowestReviewerRating method must have the following specification and functionality: o Takes the two-dimensional array as a formal parameter/argument as well as r and m o Displays each reviewer code and the highest and lowest rating. o Sample output “Highest rating for review # 1 is 6 and Lowest is 2”

Part IV (20%) [_ printAverageMovieRating] The _ printAverageMovieRating method must have the following specification and functionality: o Takes the two-dimensional array as a formal parameter/argument as well as r and m o Displays each Movie code and the average Movie rating. o Sample output : “ The average rating of the movie #4 is 6.67“

Welcome to a classic homework problem! Create a public class called Last8. You should exposed two public methods: add: adds a value, does not return a value last: returns an array containing the last 8 values that were added, in any order. You do not need a constructor, but you can add an empty one if you need. Until 8 values have been added you should return 0s in their place. For example, here's how an instance of Last8 should work:

Write a function called checkFormat that will check the format of a given username to make sure it follows some formatting restrictions. This function should take one input parameter – a string that contains the username to be checked. The username should look like [email protected] where cccc can be any 4 lowercase letters. The following conditions must be satisfied to be a valid username:

1. The length should be 19 characters

2. The 5th character should be “@”

3. The username should end with “abcdefghij.edu”

4. The username should start with 4 lowercase letters

python, use boolean function

1. Write a program that reads a positive integer n , prints all sums from 1 to any integer m 1≤m≤n . For example, if n=100, the output of your program should be

The sum of positive integers from 1 to 1 is 1;

      The sum of positive integers from 1 to 2 is 3;

      The sum of positive integers from 1 to 3 is 6;

      The sum of positive integers from 1 to 4 is 10;

      The sum of positive integers from 1 to 5 is 15;

                ⁞

      The sum of positive integers from 1 to 100 is 5050.

(The program should include a main method, and no tester class is needed)


2. You need to control the number of people who can be in an oyster bar at the same time. Groups of people can always leave the bar, but a group cannot enter the bar if they would make the number of people in the bar exceed the maximum of 100 occupants. Write a program that reads the sizes of the groups that arrive or depart. Use negative numbers for departures. After each input, display the current number of occupants. As soon as the bar holds the maximum number of people, report that the bar is full and exit the program.

Could you give some sample Java code of creating a program where users are prompt to determine how many exams they have taken then it is prompt that they have to enter their test scores and gives the sum of all their test scores? You should have to use looping

• Choose any entity of your choice to represent a superclass. It must not be any of the following:

- Human, Student, Vehicle, Person, Car, Animal

• Create a class for your entity with the following: - 3 instance variables - 3 instance methods - 2 of the instance methods must show overloading - A default constructor - A parameterized constructor that initializes all instance variables - Getters and setters for the instance variables - Method to print all the details for the class objects with captions for the data.

java language

• Create 2 subclasses for the superclass

• Each subclass must have the following: - 2 instance variables - A constructor that first initializes its object variables using the superclass constructor, then initializes the rest. - Getters and setters - A method that overrides the print method in the superclass

• Create a test class and test the print methods in all the classes.

Part 2

Write a C code to create a user defined function called RecArea that will calculate the area of a rectangle. Call the function to print the area of the rectangle on the screen.

Note: The user will enter the length and width of a rectangle (decimal values, float) and you

Part 3 (Continue on part 2)

Create another user defined function called TriArea that will calculate the area of a triangle. Print the area of the rectangle on the screen. Area of a triangle is given by:

Note: The user will enter the height and base of the triangle (decimal values or float)

Part 4 (Continue on part 3)

Sum up the two areas found in parts 2 and 3 and display the result to the user.
