So you can decide who wants to go with "X" and who wants to go with "O". Only one player can play at a time. If any of the players have filled a square then the other player and the same player cannot override that square. There are only two conditions that may match will be a draw or may win. The player that succeeds in placing three respective marks (X or O) in a horizontal, vertical, or diagonal row wins the game. Winning condition Whoever places three respective marks (X or O) horizontally, vertically, or diagonally will be the winner. Submit your code and screenshots of your code in action. Hints : Have a function that draws the board Have a function that checks position if empty or not Have a function that checks player or won or not expected output:
A company of 20 employees wants to find the employee who made the highest commission so he/she can be paid a 10% bonus of the commission he/she earned for that month. The commission an employee makes is calculated by multiplying the sales amount by the commission rate. The commission rates are shown below: Sales Amount Commission Less Than 40000 No commission 40000 to 80000 inclusive 5% Greater than 80000 10% Write a program to: Prompt the user for each employee’s id (an integer value) and the sales amount For each employee, display the commission earned Display the total commission earned by all the employees Display the average commission earned by an employee Display the employee id, the commission and the bonus paid to the employee with the highest commission Must be written in c++, no arrays to be used, only use iostream library
Control Loops: A high school 1000 students and 1000 lockers. The principal plays the following game: She asks dthe first student to open all the lockers. Shen then asks the second student to close all the even-numbered lockers. The third student is asked to check every third locker. If it is open, the student closes it; if it is closed, the student opens it. The remaining students continue this game . In general, the nth student checks every nth locker. If the locker is open, the student closes it; if it is closed, the student opens it. After all the students have taken their turns, some of the lockers are open and some are closed. Write a program thatprompts the user to enter the number of lockers in a school. After the game is over, the program outputs the number of lockers and the locker numbers of the lockers that are open. Test run your program for the following inputs: 1000, 5000, 10,000. Do you see any pattern developing for the locker numbers that are open in the output?…
