Part 2 - OddOrEven ClassIn bluej. Write a program that prompts the user to enter an integer. The program should display “The input is odd" to the screen if the input is odd and displays “The input is even" to the screen if the input is even. Hint: Consider using the mod (%) operator.
Consider the following code segment and answer questions 14 and 15. class Point { public: Point (double x = -99, double y = -99) { this -> xM = x; this -> yM = y;} double getx () {return xM; } double gety () {return yM; } void setx (double x) {this -> xM = x; } void sety (double y) {this -> yM = y; } private: double xM, yM; }; 14. What is the output of the following code snippet: Point pl (100); cout << pl.getx() << " " << pl.gety(); a. The output of the program is: -99 -99 b. The output of the program is: 100 100 c. The output of the program is: -99 100 d. The output of the program is: 100 -99 e. None of the above. It doesn't compile because constructor of Point needs two arguments. 15. How many times does the constructor of class Point get called by the following code snippet: Point a (100, 200); Point b[6]; Point *c = new Point; Point *d = new Point (300, 400); a. Four times b. Three times c. Nine times d. Two times e. None of the above
Language: JAVA Keep Guessing Write a program that plays a number-guessing game to guess a secret number randomly generated within the range 1 and 10. The user will get as many numbers of tries as he/she needs to guess the number. Tell the users if their guess is right or wrong and if their guess is wrong let them try to guess the number again. You must generate the secret number using the Java Random class. When the user guesses a number he/she will have to take an input of his guessed number from the keyboard. The user will have to take as many inputs as needed to guess the correct secret-number. That means the code will keep looping as long as the guess is different from the secret number. Use a while loop to prompt the user to guess again if the guess is wrong. Create a class named NumberGuessingGame which will contain the main method, write all your code in the main method. Sample input and output: Suppose the random number generated is 6. I have chosen a number between 1…
