- As the first step in writing an application for the local book store, we will design and implement a Book class that will define the data structure of the application. Each book has a name, author, type (paperback, hardback, magazine), integer ID and pageCount. Provide some data validation in the appropriate method to ensure that the ID and pageCount are not negative. Design and implement a Book class with separation, i.e., separate all functions and methods into both the prototype and an implementation below the main. Provide constructor methods for Book(void), Book(name, author), and one for all components Book(name, author, type, ID, pageCount) Provide accessor (get and set) methods for each property as well as a display method. Provide data validation for the ID and pageCount in the appropriate methods. Provide a method to calculate the cost for buying books (with a 7.75% sales tax) according to the following chart: Hardcover: $29.95 per book Paperback:…In your programming project, you are expected to realize the game of chance called Tombala as a C ++ console application. The details of this game played in real life are listed below: Tombala is a game of chance played over 3 sets with a minimum of 2 and a maximum of 5 players. In the tombala game, each player is given a unique (different) tombala card with 15 integers on it at the start of the game. These whole numbers in question are random numbers in the range of 1 (inclusive) to 90 (inclusive). Each set of the game makes use of a bag of stamps with consecutive integers in the range of 1 (included) to 90 (included). A check is randomly drawn from this bag each time, and each player checks if the number on that checker exists on their tombala card. This process continues similarly until the game set is completed. The player with 5 numbers on his card is deemed to have made the first zinc, the player with 10 numbers drawn from the bag, the second zinc, and the…In Java, which data type is used to store the following symbol '<' ?
- Use the following code to perform the following tasks: Show all variables that are visible at POSITION #1 only. Provide their nesting level and offset, using the activation record layout discussed in class.S2how the contents of the call stack at the time when control reaches POSITION #1. Use the layout defined in chapter 10 and used in class for statically scoped languages that allow nested functions. Show values and links. function main() {int w = 1, x = 2; function a(bool flag) {int x = 3; function b() { c(4); } function c(int x) {// POSITION #1 } b(); } a(true); } Provide a leftmost derivation for the string aaabb using the following grammar:<S> → <A><B> <A> → a<A> | a <B> → b<B> | b Identify the shortest possible legal program: <program> → program <ident> ( <ident> { , <ident> } ) <block> <ident> → A | B<block> → begin <stmts> end <stmts> → <ident> = <ident> |…Which concept is used in the following codeCreate an application on C# that has two methods. The first one calculates the area of a rectangle. The second method calculates the area of a triangle. Pass all the parameters from the main method. You must use out to pass from the main method to the first method and the second method.
- This assignment will give you a chance to perform some simple tasks with pointers. The tasks are only loosely related to each other. Start the assignment by copying the code below and pasting it into a .cpp file, then add statements to accomplish each of the tasks listed. Don't delete any of the given code or comments. Some of the tasks will only require a single C++ statement, others will require more than one. No documentation is required for this part of the assignment. /* Type your code after each of the commented instructions below (except that the statements for instructions 11 and 21 should be written where the instructions indicate). I have written the first statement for you. */ #include <iostream> using namespace std; int main() { // 1. Create two integer variables named x and y. int x; // 2. Create an int pointer named p1. // 3. Store the address of x in p1. // 4. Use only p1 (not x) to set the value of x to 99. // 5. Using cout and x (not p1), display the value of x.…What would be the missing line of codes?Application of Linear Algebra in Computer Games Write a Python game(not too long and not too complex) so that it contains attributes from Linear Algebra (matrix, vector, etc.).

- Give solution in C ++ Language with secreenshoot of source code. Part 01In this task, you need to do the following:• Write a function named displayMessage() that takes user name as input in character array and then shows greetings• Now take the name input in main() and pass the name as an argument to displayMessage() function• Change the displayMessage() method such that it returns the number of characters after displaying the greetings part 02Write a function power that takes two parameters a and b. And it returns the power as ab.Implement the Function has_error Implement the function according to the specification. Use the test script testcurrency.py to aid your development before checking your answer below. CANNOT USE IF/CONDITIONAL STATEMENTS Instead, you should use what you know about boolean expressions def has_error(json):"""Returns True if the response to a currency query encountered an error. Given a JSON string provided by the web service, this function returns True if thequery failed and there is an error message. For example, if the json is '{"success":false,"src":"","dst":"","error":"Source currency code is invalid."}' then this function returns True (It does NOT return the error message'Source currency code is invalid'). On the other hand if the json is '{"success": true, "src": "2 United States Dollars", "dst": "1.772814 Euros", "error": ""}' then this function returns False. The web server does NOT specify the number of spaces after the colons. The JSON '{"success":true, "src":"2 United…In C++ The function below, zeroesToFives takes an array of integers and changes any zeroes in the array to fives and returns the count of array elements that were updated. Write at least ten test cases using assertions for zeroesToFives. You should test at least three boundary/edge cases.
