Create any game of your choosing in MATLAB that uses at least one if statement and one switch statement. Make sure to print the rules of the game beforehand. You will get points on how fun and how complex your game is with a maximum of 4 points. A game that does not work or does not meet the conditions above will not get any points. Make sure to include the comment section to document what your program is doing. Feel free to organize your code in any way that is suitable and easy to follow.

How to Making assert Failures Start the Debugger?The Problem: A failed assert normally just prints a message and aborts the program. This is not very useful when it comes to finding problems. It would be much better if a failed assert could start the debugger.
Find the error(s) in the following code snippet and explain how to correct it (them): 1 class Example { 2 public: Example(int y = 3 10) : data (y) {} 4 int getIncrementedData() const { return ++data; 7 } 8. 9 private: 10 int data; 11 };
Edit question USING C++ *Please explain in comments in the code of what you are doing and why Implement the GradedActivity class below. class GradedActivity { private: double score; public: GradedActivity() { score = 0.0; } GradedActivity(double s) { score = s; } void setScore(double s) { score = s; } double getScore() { return score; } char getLetterGrade() const; }; Create a new class Assignment which is derived from GradedActivity. It should have three private member ints for 3 different parts of an assignment score: functionality (max 50 points), efficiency (max 25 points), and style (max 25 points). Create member function set() in Assignment which takes three parameter ints and sets the member variables. It should also set its score member, which is inherited from GradedActivity, using the setScore() function, to functionality + efficiency + style. Signature: void Assignment::set(int, int, int) Create a main program which instantiates an Assignment, asks the user for its…
You are tasked to researched about the conditional operator in java. You are to give the meaning, syntax and a sample program. You are also to tasked to compare it with if and switch in terms of functionality and use.
An set plan is beneficial. Give examples of various testing methods.
The Problem: Your program has detected an internal problem that needsdebugging. But the program is not being debugged. How do you let theprogrammer at the problem?
AS PER THE BARTELBY GUIDELINES THERE ARE 3 MULTIPLE CHOICE QUESTIONS. PLEASE ANSWER THEM ALL. 1. Analyze the following code:public class Test { public static void main(String[] args) { double radius; final double PI= 3.15169; double area = radius * radius * PI; System.out.println("Area is " + area); }}a. The program has compile errors because the variable radius is not initialized.b. The program has a compile error because a constant PI is defined inside a method.c. The program has no compile errors but will get a runtime error because radius is not initialized.d. The program compiles and runs fine. 2. Analyze the following code.public class Test { public static void main(String[] args) { int n = 2; xMethod(n); System.out.println("n is " + n); } void xMethod(int n) { n++; }}a. The code has a compile error because xMethod does not return a value.b. The code has a compile error because xMethod is not declared static.c. The code prints n is 1.d. The code prints n is 2.e. The code prints…
5) Let's say you and your friend are trying to predict the outcome of a flip of a coin. In MATLAB, create a random coin flip with heads being 1 and tails being 2. Ask the user to predict what the outcome will be. If the user predicts right, display a winning sentence and vice versa for if the user does not predict right. Afterwards, ask the user if they want to play again or stop playing. If the user elects to play again, the program should run itself from the beginning asking the user for their prediction.

c++ or java or in pseudo code with explaining note: if anything is unclear or seems left out make an assumption and document your assumption Implement an algorithm for assigning seats within a movie theater tofulfill reservation requests. Assume the movie theater has the seatingarrangement of 10 rows x 20 seats, as illustrated to the below.The purpose is to design and write a seat assignmentprogram to maximize both customer satisfaction and customersafety. For the purpose of public safety, assume that a buffer of three seats inbetween Input DescriptionYou will be given a file that contains one line of input for eachreservation request. The order of the lines in the file reflects the order inwhich the reservation requests were received. Each line in the file will becomprised of a reservation identifier, followed by a space, and then thenumber of seats requested. The reservation identifier will have theformat: R####. See the Example Input File Rows section for anexample of the input…
